Purpose To describe a case of bilateral cystoid macular edema in a patient with long-standing Tramadol hydrochloride use. Methods Observational case report. Results and discussion: A 73-year-old female patient was referred for progressive, bilateral decreased visual acuity. The patient was phakic with a best-corrected visual acuity (BCVA) at presentation was 20/50 on the right eye (RE) and 20/64 on the left eye (LE). The patient had a history of low back pain and had been on Tramadol hydrochloride 200 mg/day for 16 years. Bilateral cystoid macular edema (CME) was confirmed by means of multimodal imaging, including OCT angiography. Tramadol intake was progressively reduced over one month and then completely interrupted. At three months follow-up, the cystoid macular edema had completely resolved and BCVA improved in both eyes. Conclusion CME may be associated with longstanding treatment with Tramadol hydrochloride. Tramadol hydrochloride associated CME is described, as well as its resolution on Tramadol cessation.

Cystoid Macular Edema (CME) in its various forms can be considered one of the leading causes of central vision loss in the developed world. It is not a disease itself, It represents a common pathologic sequel of the retina and occurs in a variety of pathological conditions such as, diabetic retinopathy, central or branch retinal vein occlusion, intraocular inflammation and following cataract extraction. This study was done to investigate the pattern of CME in patient attending Erbil Teaching Hospitals. This is a hospital base prospective study that included 61 patients (75 eyes) conducted at Erbil Teaching Hospital and Rigor Teaching Hospital for six months. All patients underwent a comprehensive assessment including medical and ophthalmic history and detailed ophthalmic examination including slit lamp examination, intraocular pressure measurement (IOP), Best corrected visual acuity (BCVA), dilated fundus examination and Optical Coherence Tomography (OCT) examination. It was found that of the 61 patients 32 (52.5%) were females and 29 (47.5%) were males. The mean age (56.4±10.8) years. Out of the 75 eyes included in the study, 41 eyes (54.66%) had diabetic retinopathy, 10 (13.34%) eyes had CME following cataract operation (Irvine-Gass syndrome), 8 eyes (10.67%) had BRVO, 6 eyes (8%) were had CRVO, 5 eyes (6.66%) had Age related Macular Degeneration, 3 eyes (4%) with uveitis, and 2 (2.67%) had Retinitis Pigmentosa. The average macular thickness was (415.6± 107). It was concluded that diabetic retinopathy is the most common predictive factor of CME, followed by cataract surgery. CME is more severe in diabetic retinopathy, CRVO and after cataract surgery.

To report a case of a pituitary macroadenoma that presented with bilateral intraretinal hyporeflective spaces located primarily in the inner nuclear layer on the macular SD-optical coherence tomography.Case report.Based on the findings of a macular SD-optical coherence tomography, a 53-year-old man was considered as having cystoid macular edema secondary to a retinovascular condition. He was treated with intravitreal vascular endothelial growth factor inhibitors and corticosteroids with no improvement. Confrontation visual fields suggested a bitemporal defect. MRI confirmed the presence of a nonsecreting pituitary macroadenoma compressing the optic chiasm.Not all intraretinal hyporeflective spaces in the optical coherence tomography are secondary to a retinal vascular condition. Hyporeflective spaces in the inner nuclear layer on optical coherence tomography imaging that do not leak on fluorescein angiography may be secondary to optic atrophy from chiasmal compression.

Postoperative cystoid macular oedema (CMO) is a recognised complication of cataract surgery, occurring in around 1.5% of cases. It is generally managed with topical steroids or non-steroidal anti-inflammatory medications. We present a case of a patient who developed bilateral sequential CMO following bilateral sequential cataract surgery which was non-responsive to topical therapy and worsened following sub-Tenons administration of steroid. The patient took fingolimod for multiple sclerosis both prior to and during the period of cataract surgery which is known to result in the development of macular oedema in some patients. On fingolimod cessation, the oedema resolved over a period of 5 months with good visual recovery. We present this case to inform cataract surgeons of the risk of fingolimod-associated macular oedema in patients undergoing cataract surgery and to inform neurologists of the potential need to adjust treatment for patients undergoing cataract surgery.

Purpose To report a case of bilateral sequential, CRVO in a man with newly diagnosed hemoglobin C trait. Methods A 67-year-old man presented with a one-month history of declining visual acuity. He was diagnosed with left CRVO. Bilateral temporal retinal ischemia and arteriovenous anastomoses on fluorescein angiography suggestive of sickle cell retinopathy prompted a systemic work-up. Hemoglobin electrophoresis revealed an underlying hemoglobin C trait. Six-months after his initial presentation, the patient developed symptomatic right CRVO. Results The initial left CRVO was complicated by optic disc swelling and macular edema. Intravitreal anti-angiogenic therapy was initiated and the macular edema resolved. The left eye subsequently developed an epiretinal membrane which was surgically removed. Macular edema in the right eye also resolved after intravitreal anti-angiogenic therapy. Conclusion This is the first reported case of bilateral CRVO in a case of hemoglobin C trait. It is possible that erythrocyte inflexibility, caused by hemoglobin C induced dehydration and crystallization, acted concomitantly with hypertension to produce occlusive microangiopathy. This case highlights the need for further investigation in patients presenting with central retinal vein occlusion, especially when bilateral, or when retinal angiography reveals bilateral pathology.

To report a case of nonleaking cystoid macular edema (CME) associated with pentosan polysulfate sodium (PPS)-induced pigmentary maculopathy.Multimodal imaging, including optical coherence tomography, fundus photography, autofluorescence, and fluorescein angiography, was used to substantiate our diagnosis, further characterize the cystoid macular edema showed by our patient and to monitor the response to treatment.A 59-year-old woman was referred for decreased visual acuity and bilateral macular edema. She had been treated for interstitial cystitis with PPS for 10 years. Multimodal imaging showed the characteristic features of PPS-induced pigmentary maculopathy. Moreover, fluorescein angiogram showed nonleaking cystoid macular edema in both eyes. She was treated successfully with intravitreal injections of bevacizumab.To our knowledge, this report is the first to demonstrate that PPS-associated cystoid macular edema can be nonleaking on fluorescein angiography and responds well to intravitreal anti-vascular endothelial growth factor injections.

To present a case of idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome that was successfully managed with serial intravitreal aflibercept injections.Ophthalmic imaging and visual acuity were used to monitor disease state and track treatment methods to determine the most valuable combination of treatment medication and treatment interval.A 28-year-old woman with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome status after panretinal photocoagulation of both eyes presented with bilateral cystoid macular edema. We demonstrate successful management of retinal cystoid macular edema associated with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome using serial intravitreal aflibercept injections.Intravitreal aflibercept has a useful role in managing the potential retinal complications associated with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome and provides further insights into treatment of the later stages of this rare disease.

To describe the occurrence of full-thickness macular hole formation and spontaneous closure in a case of central retinal vein occlusion treated with intravitreal ranibizumab.A 67-year-old hypertensive man presented with acute central retinal vein occlusion with macular edema in his left eye for which he received intravitreal ranibizumab.He developed a FTMH following the second injection, which was kept under observation. Recurrence of intraretinal edema allowed approximation of the MH edges which subsequently achieved closure with further intravitreal RBZ and formation of an epiretinal membrane.Full-thickness macular hole formation in acute central retinal vein occlusion after intravitreal ranibizumab, although rare, can occur in eyes with massive macular edema and absence of posterior vitreous detachment after intravitreal pharmacotherapy. Spontaneous closure of secondary holes can take place with improvement in visual acuity.

To report the clinical course and treatment outcomes of a patient with central retinal vein occlusion with severe macular edema in early pregnancy.Interventional case report.A 39-year-old woman with gestational diabetes mellitus and a 15-pack year smoking history presented at 7 weeks gestation with decreased vision due to central retinal vein occlusion with marked macular edema. One month later, visual acuity had decreased to 20/400, and macular edema had worsened to a central subfield thickness of 1,432 μ m. She was treated with a single intravitreal dexamethasone implant at 16 weeks gestation. She responded well with visual acuity improving to 20/40+ and complete resolution of macular edema. At 33 weeks gestation, the cystoid macular edema recurred, but the patient refused treatment. The cystoid macular edema spontaneously resolved 3 weeks postpartum but recurred 3 months later with visual acuity worsening to 20/50. This macular edema resolved completely after a single 1.25 mg bevacizumab injection. She required no further treatment, and 23 months later, her macula was dry with visual acuity of 20/25. Her baby was healthy.Although pregnancy seems to aggravate central retinal vein occlusion -associated macular edema, the visual loss may be reversible. Intravitreal steroid seems to be effective during pregnancy with no apparent systemic or fetal complications. Young patients with retinal vein occlusion and center-involving macular edema may stabilize with minimal treatment.

Concomitant vitamin D deficiency (VDD) is speculated to aggravate diabetic macular edema (DME). We aimed to determine the effect of hypovitaminosis D correction on the outcome of treatment with intravitreal bevacizumab (IVB) in DME eyes.In this randomized clinical trial, 83 eyes of 83 patients with DME were recruited and divided into three groups: normal vitamin D levels + IVB administration (Group 1), vitamin D insufficient/deficient + IVB administration (Group 2), and vitamin D insufficient/deficient + IVB administration + oral vitamin D supplementation (Group 3). Participants were followed for 6 months after the intervention. Visual (corrected distance visual acuity, CDVA) and anatomical (central macular thickness, CMT) outcomes of intervention were evaluated 1, 3, and 6 months after three monthly loading doses of IVB were given. Serum vitamin D levels were measured 1 and 6 months after the third IVB administration.A total of 29, 26, and 28 eyes were enrolled in groups 1, 2, and 3, respectively. In months 1, 3, and 6, after the three basic loading doses of IVB, visual acuity and CMT improved in all three groups, but improvements (both functional and anatomical) in groups 1 and 3 in month 6 were more significant than in group 2 (mean CDVA LogMAR changes: - 0.18 ± 0.03, - 0.14 ± 0.05, and - 0.2 ± 0.06; mean CMT reductions: - 82.24 ± 11.43, - 66.62 ± 14.34, and - 86.14 ± 18.36, in groups 1, 2, and 3, respectively; p 0.001). The mean number of IVB injections during follow-up was 5.33 (range 4-7), which did not differ between the groups.Correction of vitamin D deficiency in DME patients with type 2 diabetes and vitamin D deficiency, in addition to IVB injections, may play a role in improving CDVA and CMT. However, this beneficial effect seems to be delayed by several months.Iranian Registry of Clinical Trials (IRCT), IRCT20200407046978N1, registered on April 11, 2020, retrospectively registered ( https://en.irct.ir/trial/46999 ).

PURPOSE: To investigate the cost-effectiveness of prophylactic treatments against cystoid macular edema (CME) after cataract surgery in diabetic patients.SETTING: Seven ophthalmology clinics in the Netherlands and Belgium.DESIGN: Prospective trial-based cost-effectiveness analysis using data from a European multicenter randomized clinical trial.METHODS: Diabetic patients (n=163) undergoing uncomplicated cataract surgery were randomized to perioperative subconjunctival triamcinolone acetonide (n=36), perioperative intravitreal bevacizumab (n=36), combination treatment (n=45), or no additional treatment (control group, n=46). The cost analysis was performed from a healthcare perspective within a 12-week postoperative time horizon. The main effectiveness outcome was quality-adjusted life years (QALYs). The main cost-effectiveness outcome was the incremental cost-effectiveness ratio (ICER; cost per QALY).RESULTS: Mean total healthcare costs and QALYs were: Triamcinolone € 1827 (US$ 2295) / 0.166; Bevacizumab € 2050 (US$ 2575) / 0.144; Combination € 2027 (US$ 2546) / 0.166; Control € 2041 (US$ 2564) / 0.156. Bevacizumab and control treatment were most costly and least effective. The ICER was € 321,984 (US$ 404,503) per QALY for the combination group compared to the triamcinolone group. Assuming the willingness-to-pay is € 20,000 (US$ 25,126) per QALY, the cost-effectiveness probability was 70% and 23% in the triamcinolone and combination groups, respectively. No patient that received triamcinolone developed clinically significant macular edema (CSME). A secondary cost-effectiveness analysis based on this outcome showed a clear preference for triamcinolone.CONCLUSIONS: In diabetic patients, subconjunctival triamcinolone was effective in preventing CSME after cataract surgery. The cost-effectiveness analysis showed triamcinolone is also cost-effective.

Objective To analyze the factors associated with response (control of ocular inflammation and corticosteroid sparing effect) to biologics (anti-TNF-α agents and tocilizumab) in patients with refractory uveitic macular edema. Design Multicenter retrospective observational study. Subjects Adult patients with uveitic macular edema refractory to systemic corticosteroids and/or disease modifying anti-rheumatic drugs. Methods Patients received anti-TNF-α agents [IFX 5 mg/kg at weeks 0, 2, 6 and every 4-6 weeks (n=69) and ADA 40 mg/14 days (n=80)] and tocilizumab [8 mg/kg every 4 weeks intravenously (n=39) and 162 mg/week subcutaneously (n=16)]. Main Outcome Measures Analysis of complete and partial response rates, relapse rate, low vision (visual acuity in at least one eye ≥ 1 LogMAR), corticosteroid sparing effect and adverse events at 6 months. Results 204 patients (median age of 40 years [28-58] with 42.2% of men) were included. Main etiologies of uveitis included Behcet’s disease (17.2%), birdshot chorioretinopathy (11.3%) and sarcoidosis (7.4%). The overall response rate at 6 months was of 46.2% (21.8% of complete response) with anti-TNF-α agents and 58.5% (35.8% of complete response) with tocilizumab. In multivariate analysis, treatment with tocilizumab (OR 2.10 [95% CI 1.06–4.06], p=0.03) was independently associated with complete response of uveitic macular edema, compared to anti-TNF-α agents. Anti-TNF-α agents and tocilizumab did not differ significantly in terms of relapse rate (HR=1.00 [0.31-3.18], p=0.99) or occurrence of low vision (OR=1.02 [0.51-2.07], p=0.95) or corticosteroid-sparing effect (p=0.29). Adverse events were reported in 20.6% of patients, including 10.8% of serious adverse events. Conclusions Tocilizumab seems to improve complete response of uveitic macular edema compared to anti-TNF-α agents.

PURPOSE To assess the relationship between best corrected visual acuity (BCVA) and central subfield optical coherence tomography (OCT) features in noninfectious uveitis (NIU)-related macular edema (ME). DESIGN Clinical cohort study from post hoc analysis of two phase 3 clinical trials' data. METHODS Correlation and longitudinal treatment analyses were performed. Of 198 patients with NIU, 134 received suprachoroidally administered CLS-TA (Clearside Biomedical, Inc. proprietary formulation of a triamcinolone acetonide injectable suspension) and 64 received sham, with 12.9% and 72% respectively receiving rescue therapy. RESULTS At baseline, mean BCVA progressively worsened with each ordinal drop in ellipsoid zone (EZ) integrity. Eyes with normal baseline EZ experienced greater 24-week change in BCVA compared to eyes with some degree of baseline EZ disruption (11.9 vs 9.4 letters, P=0.006). In contrast, eyes without central subfield cystoid spaces and/or central subfield SRF at baseline showed less improvement (5.5 letters or 9.5 letters, respectively) at 24 weeks, compared to those eyes with such OCT findings (13.7 letters, P = 0.012 or 17.2 letter, P

Aim To determine the association and the prognostic value of soluble ST2 (sST2) levels in the development of diabetic retinopathy (DR), diabetic macular oedema (DMO) or diabetic nephropathy (DN), in a cohort of patients with type 1 diabetes (T1D). Methods A total of 269 individuals with T1D (154 males and 115 females) were recruited. The overall mean age was 43.2 ± 14.9 years, and the diabetes duration was 17.1 ± 12.1 years. Levels of sST2 in serum were evaluated, and the presence as well as the degree of DR, DMO and DN was recorded. Additionally, other clinical and analytical parameters including demographic variables were recovered from patients’ electronic health record. Ten years later, the presence and stage of DR, DMO and DN were again recorded under the same criteria. The association between previously mentioned parameters with DR and DN was analysed by univariate and multivariate logistic regression. The variables in the final multivariate models were adjusted from complete models via backward elimination and maintained only when significant. Results An increase of 10 ng/ml in the levels of sST2 was associated with a 1.50 (1.02–2.19) and 1.48 (1.05–2.08) prevalence odds ratio (OR) in DMO and DR, respectively. There was no association between sST2 levels and DN. Meanwhile, sST2 levels did not display a prognostic effect in any of the microangiopathic diabetic complications studied. Conclusions Levels of sST2 are associated with the presence of DR and DMO, they do not seem to be predictive for the development or deterioration of DR, DMO or DN.

A 61-year old male was referred to the Ophthalmology department because of decreased bilateral visual acuity. The patient had metastatic pancreatic adenocarcinoma and was being treated with gemcitabine+nab-paclitaxel. On examination, the patient presented best corrected visual acuities of 4/20 and 2/20 in the right and left eye, respectively. The optical coherence tomography revealed bilateral severe macular edema. Macular edema was considered secondary to nab-paclitaxel and the drug was discontinued. Three months after drug discontinuation, the patient presented best corrected visual acuities of 20/20 and 16/20 in the right and left eye, respectively, and normal fundoscopy. Macular edema is a very rare side effect of taxanes, and the etiopathology is still unknown. Edema is usually reversible upon discontinuation of the offending agent. Clinicians should be aware of this adverse effect of taxanes, and a high index of clinical suspicion is essential for diagnosis.Doente do sexo masculino, de 61 anos de idade, foi encaminhado para Oftalmologia por queixas de diminuição da acuidade visual bilateral. Tratava-se de um doente com um adenocarcinoma pancreático metastizado, sob tratamento com gemcitabina+nab-paclitaxel. Ao exame oftalmológico, o doente apresentava melhores acuidades visuais corrigidas de 4/20 e 2/20 do olho direito e esquerdo, respetivamente. A tomografia de coerência ótica revelou a presença de edema macular bilateral grave. O edema macular foi considerado secundário ao uso de nab-paclitaxel, pelo que o fármaco foi suspenso. Três meses após a suspensão do fármaco, o paciente apresentava acuidades visuais de 20/20 e 16/20 do olho direito e esquerdo, respetivamente, e uma fundoscopia normal. O edema macular é um efeito adverso muito raro dos taxanos e a sua etiopatologia ainda não se encontra totalmente esclarecida. O edema é habitualmente reversível após a suspensão do agente causador. Um elevado índice de suspeição é essencial para o diagnóstico desta condição.

To investigate, by means of spectral domain optical coherence tomography, retinal reflectivity changes as an early biomarker anticipating radiation-induced macular edema (ME) in patients treated by iodine-125 (I-125) brachytherapy.Thirty patients planned for I-125 brachytherapy because of uveal melanoma were prospectively included and followed every 4 months for five years. Reflectivity alterations, namely hyperreflective retinal foci, were characterized and counted by two independent masked examiners by means of spectral domain optical coherence tomography imaging. Hyperreflective retinal foci were defined as discrete intraretinal reflectivity changes ≤30 µm, with reflectivity similar to nerve fiber layer and without back shadowing.Macular edema occurred in 17 patients (24.2 ±15.1 months) (group 1) after irradiation. Thirteen patients showed no signs of ME at the 5-year follow-up (group 2). The number of hyperreflective retinal foci was statistically higher in sequential visits until the evidence of ME in group 1 vs group 2 (P0.0001). In group 1, hyperreflective retinal foci at the follow-up before the evidence of ME were significantly related to the OCT central subfield thickness at ME appearance (P = 0.0002, r2=0.6129). The intergrader agreement was almost perfect (intraclass correlation coefficient = 0.80).Hyperreflective retinal foci may be considered as an early in vivo imaging biomarker of retinal inflammatory response to ocular irradiation, anticipating the development of radiation maculopathy.

Purpose To determine if treatment with a photobiomodulation (PBM) device results in greater improvement in central subfield thickness as compared with placebo in eyes with center-involved diabetic macular edema (CI-DME) and good vision Design Phase 2 randomized clinical trial Participants Participants had CI-DME and visual acuity (VA) 20/25 or better in the study eye and were recruited from 23 clinical sites in the US. Methods One eye of each participant was randomly assigned 1:1 to a 670-nm light-emitting PBM eye patch or an identical device emitting broad-spectrum white light at low power. Treatment was applied for 90 seconds twice daily for 4 months. Main Outcome Measure Change in central subfield thickness (CST) on spectral-domain optical coherence tomography (OCT) at 4 months. Results From April 2019 to February 2020, 135 adults were randomly assigned to either PBM (N = 69) or placebo (N = 66); median age was 62, 37% were female and 82% were white. Median device compliance was 92% with PBM and 95% with placebo. OCT CST increased from baseline to 4 months by a mean (SD) of 13 (53) μm in PBM eyes and 15 (57) μm in placebo eyes (mean difference (95% CI) = -2 (-20 to 16) μm; p = .84). CI-DME, based on DRCR Retina Network sex and machine-based thresholds, was present in 61 (90%) of PBM eyes and 57 (86%) of placebo eyes at 4 months (adjusted odds ratio (95% CI) = 1.30 (0.44 to 3.83); p = .63). Visual acuity decreased by a mean (SD) of -0.2 (5.5) letters and -0.6 (4.6) letters in the PBM and placebo groups, respectively (difference (95% CI) = 0.4 (-1.3 to 2.0) letters; p = .64). There were eight adverse events possibly related to the PBM device, and two adverse events possibly related to the placebo device. None were serious. Conclusions PBM as given in this study, while safe and well tolerated, was not found to be effective for the treatment of CI-DME in eyes with good vision.

Purpose To calculate costs required to prevent center-involved diabetic macular edema (CI-DME) or proliferative diabetic retinopathy (PDR), and to improve the diabetic retinopathy severity score (DRSS) with intravitreal anti-VEGF injections as reported for aflibercept in two randomized control trials. Design Cost-effectiveness analysis modeling based on published data Subjects None Methods Results from PANORAMA and the Diabetic Retinopathy Clinical Research Network ( DRCR.net ) Protocol W were analyzed. Parameters collected included DRSS score, risk reduction of PDR, risk reduction of CI-DME, and number of treatments required. Costs were modeled based on 2020 Medicare reimbursement data practice settings of hospital-based facility and non-facility. Main Outcome Measure Cost to prevent case of PDR and CI-DME, and to improve DRSS stage Results Over 2 years in Protocol W, the cost required to prevent 1 case of PDR was $83,000 ($72,400) in the facility (non-facility) setting; in PANORAMA, the corresponding 2 year costs were $89,400 ($75,000) for the 2Q16 arm, and $91,200 ($89,900) for the 2Q8PRN arm. To prevent 1 case of CI-DME with vision loss in Protocol W, the cost was $154,000 ($133,000). For all CI-DME, with and without vision loss; in PANORAMA, the costs to prevent a case were $70,900 ($59,500) for the 2Q16 arm, and $90,000 ($88,800) for the 2Q8PRN arm. In Protocol W, the overall accumulated total for cost /DRSS unit change at the 2 year point for facility (non-facility) setting was $2700 ($2400)/DRSS. In the first year alone, it was $2100 ($1800)/DRSS and in the second year alone, $6100 ($5300)/DRSS. Conclusion There is a considerable cost associated with the prevention of PDR and CI-DME with intravitreal aflibercept injections. A price per unit of change in diabetic retinopathy severity score is a new parameter which might serve as a benchmark in future utility analyses that could be used to bring perspective to cost-utility considerations.

Purpose To present a case of endophthalmitis caused by Abiotrophia defectiva after repeated injections of dexamethasone intravitreal implant (Ozurdex), in a patient already on systemic immunosuppressive therapy, and discuss the management of this challenging situation. Methods Case report and review of literature. Results A 70-year-old female patient with history of idiopathic pulmonary fibrosis presented for urgent evaluation due to left eye vision loss and mild discomfort 12 days after receiving her seventh dexamethasone implant injection. Ocular history was pertinent for recurrent macular edema resulting from a remote branch vein occlusion. Twelve days after her last injection, visual acuity decreased from 20/30 to counting fingers at 5 feet. Slit-lamp examination showed anterior chamber cell without fibrinoid membranes or hypopyon. Within hours, the patient's clinical appearance progressed. A vitreous tap followed by intravitreal injection of vancomycin (1 mg/0.1 mL) and ceftazidime (2.25 mg/0.1 mL) was performed. The culture from the vitreous sample revealed heavy growth of A. defectiva. Owing to limited improvement, patient was taken to the operating room, and the presence of a full-thickness scleral defect at the site of most recent dexamethasone implant injection was confirmed. Vitrectomy with removal of implant, closure of all sclerotomies, including nonhealing full-thickness scleral defect, and repeated intravitreal antibiotic injection were performed. At the 3-month follow-up, no inflammation was observed, but visual acuity remained poor. Conclusion Intravitreal dexamethasone implant-associated endophthalmitis in the setting of systemic immunosuppression is a rare and challenging situation. Both local and systemic immunosuppression may delay wound healing, predisposing to wound leakage and consequent endophthalmitis. Despite repeated intravitreal antimicrobial injection and vitrectomy with implant removal, A. defectiva endophthalmitis carried a poor visual outcome.

Purpose: To determine the magnitude, determinants, and public health issues related to diabetic retinopathy (DR) in India using 2019 data from a for-profit telescreening program. Methods: Digital retinal images were captured using a nonmydriatic fundus camera and transferred via the telescreening program to a reading center. Ophthalmologists trained in DR image reading created the DR status reports. Age/sex-adjusted rates of DR, sight-threatening DR (STDR), and diabetic macular edema (DME) were calculated and correlated with known risk factors. Results: Images of 51,760 Indian diabetic patients (103,520 eyes) were reviewed. The prevalence of DR, STDR, and DME was 19.1% (95% confidence interval [CI]: 18.9-19.5), 5.1% (95% CI: 4.9-5.3), and 3.9% (95% CI: 3.7-4.1), respectively. Based on these data, we projected 14.7 million cases of DR, 3.9 million with STDR, and 3.0 million DME cases in India. Statistically significant risk factors for DR were male gender (odds ratio [OR] = 1.19, p < 0.001), older age (χ2 = 270, df = 3, p < 0.001), history of cataract surgery (OR = 2.0, p < 0.001), longer duration of diabetes (χ2 = 1084, p < 0.001), and type 1 diabetes (OR = 3.9, p = 0.01). There was a statistically significant variation of DR by geographic zones (χ2 = 310, p < 0.001). Laser treatment coverage for STDR was 22%. Duration of diabetes (p < 0.001), cataract surgery in the past (p = 0.02), and females (p = 0.001) were predictors of STDR. Conclusion: This model of telescreening for DR provides an additional pathway for screening and preventing diabetes-related visual morbidity in India. The data from this study can be used for epidemiologic and ophthalmic health policies related to diabetes.

Purpose : To evaluate the effect of loss to follow up (LTFU) on outcomes in eyes with diabetic macular edema (DME) treated with anti-vascular endothelial growth factor (VEGF). Design : Retrospective cohort study Methods : Single-center study of 90 eyes of 73 patients with non-proliferative diabetic retinopathy (NPDR) and DME treated with anti-VEGF injections who were LTFU for >6 months. Main outcomes were the change in mean visual acuity (VA) and central foveal thickness (CFT) at the return and final visits compared to the visit before LTFU. Results : Mean age was 64.5 years, mean LTFU duration was 322 days, and mean follow-up duration after return was 502 days. Compared to the mean VA at the visit before LTFU (0.42, Snellen ∼20/52), mean VA worsened at the return visit (0.54, Snellen ∼20/69, p=0.004). No significant change in the mean VA was noted at the 3-month after return visit (0.50, Snellen ∼20/63), the 6-month after return visit (0.46, Snellen ∼20/57), the 12-month after return visit (0.42, Snellen ∼20/52) and the final follow up (0.47, Snellen ∼20/59). When analyzed by NPDR severity before LTFU, no difference in VA was found from the visit before LTFU to the final visit. Mean CFT increased when comparing the visit before LTFU (270 μm) to the return visit (305 μm, p=0.012), but no difference was found by the final visit [247 μm, p=0.07]. Conclusions : Anti-VEGF treated DME patients who were LTFU for a prolonged period experienced a modest decline in VA that recovered after restarting treatment.

Purpose To report the efficacy of photodynamic therapy (PDT) for management of retinal hemangioblastoma. Design Retrospective case series. Participants Seventeen patients with retinal hemangioblastoma treated with PDT. Methods The medical records of 17 patients with retinal hemangioblastoma treated with PDT were reviewed, and treatment outcomes were assessed. Photodynamic therapy was performed with 6 mg/m2 body surface area of verteporfin infused intravenously over 10 minutes activated by 50 J/cm2 laser light at 689 nm for 83 or 166 seconds. Main Outcome Measures Tumor control, subretinal and intraretinal fluid resolution, and visual outcome. Results Eighteen retinal hemangioblastomas in 17 eyes were treated with PDT. Median patient age was 31 years (mean, 36 years; range, 7–66 years), and median follow-up was 51 months (mean, 61 months; range, 2–144 months). Genetic testing confirmed von Hippel-Lindau disease in 8 of 17 patients (47%). The tumors were unilateral in all patients and unifocal in most patients (n = 13/17 [76%]). The tumor median basal diameter was 3.5 mm (mean, 3.4 mm; range, 1.5–6.0 mm) and median thickness was 2.1 mm (mean, 2.3 mm; range, 1.0–5.0 mm). The tumor location was juxtapapillary in 9 of 18 cases (50%). Associated findings included subretinal fluid (n = 14/17 [82%]) and macular edema (n = 12/17 [71%]). The median number of PDT sessions was 1.5 (mean, 1.8; range, 1.0–4.0). Standard duration of PDT (83 seconds) was used in all cases except 2, in which double duration (166 seconds) was used. Outcomes revealed tumor control in 13 of 18 tumors (72%), partial or complete resolution of subretinal fluid in 10 of 14 eyes (71%), and partial or complete resolution of macular edema in 7 of 12 eyes (58%), and stable or improved visual acuity in 12 of 17 eyes (71%). Photodynamic therapy-related transient exudative response was noted in 4 of 17 eyes (24%). Conclusions Photodynamic therapy is an effective treatment for both juxtapapillary and peripheral retinal hemangioblastomas, providing satisfactory rates of tumor control and visual stabilization and improvement. Patients should be monitored for PDT-related transient exudative response.

Background: Dynamic Contrast-enhanced Magnetic Resonance Imaging (DCE-MRI) technique could not only quantify blood-retinal barrier (BRB) breakdown leading to macular edema associated with diabetes, but also provide a two-dimensional imaging method that is not interfered by refracting media. Objective: The current study was aimed to evaluate the macular change in the patients with diabetic retinopathy using DCE-MRI technique. Methods: Twenty patients with Diabetic Retinopathy (DR) and 20 Normal Controls (NC) were included. The fast spoiled gradient echo sequence was used to perform dynamic contrast T1WI enhancement on 3.0T MR system. The macular region, optic papila and nasal retina were performed with quantitative DCE-MRI evaluation using Omni-Kinetics software. Results: The maximal concentration, the area under the concentration-time curve (AUCconcentration-time) and maximal slope of macular region were significantly higher in DR [0.270(0.03,1.20)mmol/ 100ml, 2.71(0.04,9.91) mmol*min and 0.38(0.06,3.18) mmol/min, respectively] than that [0.169(0.03,0.72) mmol/1.25(0.13,10.41) mmol*min and 0.245(0.06,1.34) mmol/min] in NC (U value = 515.00 and P value = 0.080, U value = 433.00 and P value = 0.000, and U value = 563.00 and P value = 0.023, respectively). The receiver operating characteristic curve (ROC) analysis demonstrated that the area under AUCconcentration-time was 0.729±0.058 with the cut-off value 1.479 mmol*min (sensitivity 80.00% and specificity 62.50%) for macular region. Conclusion: The quantitative DCE-MRI technique could be used to evaluate the maculopathy associated with diabetic retinopathy.

Pentosan polysulfate sodium (PPS), a semisynthetic sulfated polysaccharide, is the only FDA-approved oral therapy for interstitial cystitis. Recent studies have described a progressive, vision-threatening macular condition associated with long-term PPS use. We reviewed all publications concerning PPS maculopathy to consolidate known clinical features and to evaluate the strength of this association. Current literature supports a strong dose-dependent association between PPS exposure and a progressive maculopathy impacting the retinal pigment epithelium (RPE) and RPE-photoreceptor interface that may worsen even after drug cessation. Initial symptoms may include prolonged dark adaptation and difficulty reading with relative visual acuity preservation. Fundus examination often shows macular pigment clumps corresponding to lesions of focal RPE thickening. Fundus autofluorescence most clearly depicts the condition, with a distinctive pattern of hypo- and hyperautofluorescent spots in the posterior pole that sometimes extends to the retinal periphery. Many cases also show a characteristic peripapillary hypoautofluorescent halo. Near infrared reflectance may aid in early detection. RPE atrophy, cystoid macular edema, and macular neovascularization may also occur, potentially resulting in loss of central acuity. This newly described association implies significant public health risk. Ophthalmologists should screen PPS users with multimodal retinal imaging, and prescribers should minimize dose and duration of PPS use.

Background This post hoc analysis compared the efficacy and safety of CLS-TA to other commonly available treatments for noninfectious uveitis (NIU). Methods Results from the PEACHTREE study were compared between subjects randomized to CLS-TA not requiring rescue therapy and those subjects randomized to control and subsequently requiring rescue therapy. Endpoints included best corrected visual acuity (BCVA), central subfield thickness (CST), treatment emergent adverse events (TEAEs), and intraocular pressure (IOP) related safety findings. Results In this analysis, there were 83 unrescued CLS-TA subjects and 46 rescued control subjects. At Week 24, 51.9% of the unrescued CLS-TA subjects gained ≥15 letters in BCVA, compared to 37.0% of the rescued control subjects (P = 0.115). Unrescued CLS-TA subjects showed a mean gain of 15.7 versus 10.9 letters in rescued control subjects (P = 0.080). A significantly greater mean reduction in CST was observed for unrescued CLS-TA subjects versus rescued control subjects (174.0 and 148.5 μm; P = 0.040). Of unrescued CLS-TA subjects, 4.9% experienced IOP elevations ≥ 30 mm Hg at any visit versus 10.9% of rescued control subjects. Further, use of IOP-lowering medications appeared lower in unrescued CLS-TA subjects versus rescued control subjects (7.2% versus 13.0%). There were no IOP-related surgical interventions in either group. Conclusion CLS-TA subjects experienced significantly greater reduction in CST and tended towards greater improvement in BCVA, compared with rescued control subjects. Suprachoroidally administered CLS-TA showed a lower incidence of IOP-related safety findings. This article is protected by copyright. All rights reserved.

PURPOSE To describe uveitis cases after the BNT162b2 mRNA SARS-CoV-2 vaccination. METHODS This is a multicenter, retrospective study. Vaccine-related uveitis diagnosis was supported by the classification of the World Health Organization Adverse Drug Terminology and the Naranjo criteria. RESULTS Twenty-one patients (23 eyes) with a mean age of 51.3 years (23-78 years) were included. Eight of the 21 patients had a known history of uveitis. The median time from previous to current attack was 1 year (0.5-15 years). There were 21 anterior uveitis cases, two with bilateral inflammation. Eight cases occurred after the first vaccination and 13 after the second vaccination. All but three presented as mild to moderate disease. Two patients developed multiple evanescent white dot syndrome after the second vaccination. The mean time from vaccination to uveitis onset was 7.5 ± 7.3 days (1-30 days). At final follow-up, complete resolution was achieved in all but two eyes, which showed significant improvement. One case of severe anterior uveitis developed vitritis and macular edema after the second vaccination, which completely resolved after an intravitreal dexamethasone injection. CONCLUSION Uveitis may develop after the administration of the BNT162b2 mRNA vaccine. The most common complication was mild to moderate anterior uveitis, while multiple evanescent white dot syndrome can also occur less frequently.

To compare changes in optic disc microvascular parameters before and after treatment of patients who received IVD for macular edema secondary to BRVO, using optical coherence tomography angiography (OCT-A).Eighteen BRVO patients who received only IVD treatment and 20 healthy controls were retrospectively reviewed. Patients with moderate or severe IOP spikes (6mmHg) after implantation were excluded from the study. Whole, peripapillary, inside disc capillary density and retinal nerve fiber layer thickness (RNFLT) were recorded at the 2nd and 6th months after implantation.Whole, peripapillary and inside disc capillary densities were significantly lower in BRVO patients before implantation than in the control group (P0.001 for all comparisons). Despite a mild mean IOP increase after IVD, no significant change was observed in whole, peripapillary and inside disc capillary vascular densities in the 2nd and 6th months (P0.05 for all comparisons). The mean RNFLT of BRVO patients before IVD was lower than the control group, but this difference was not statistically significant (110.1±12.3μm and 115.6±10.7μm, P=0.131). The mean RNFLT at the 2nd and 6th months did not show a statistically significant difference after implantation (P=0.239, P=0.459).OCT-A shows the decrease in whole, peripapillary and inside disc microvascular parameters in BRVO patients compared to healthy subjects. No significant change in optic nerve head microvascular parameters was observed in patients without moderate or severe IOP spikes after treatment with IVD.

The purpose of current study was to evaluate different optical coherence tomography angiography (OCTA) metrics in eyes with diabetic retinopathy with and without diabetic macular edema (DME). In this retrospective study, macular OCTA images of eyes with non-proliferative or proliferative diabetic retinopathy were evaluated. Vascular density, vascular complexity and non-perfusion densities were compared between eyes with and without DME. One-hundred-thirty-eight eyes of 92 diabetic patients including 49 eyes with DME were included. In multivariate analysis, the presence of DME was positively associated with geometric perfusion deficit (GPD) in superficial capillary plexus (SCP), capillary non-perfusion (CNP) of SCP, and GPD in deep capillary plexus (DCP) (all P

Purpose To elucidate strategies for and controversies surrounding the use of anti-inflammatory medications after uneventful cataract surgery, with a focus on the prevention of irreversible vision loss due to cystoid macular edema (CME). Design Perspective. Methods Expert commentary on the management of inflammation after cataract surgery. Discussion includes combination therapy with corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs), dosing strategies, and emerging therapies. Results While prescribing both NSAIDs and corticosteroids for cataract surgery is common, these classes have overlapping mechanisms. Combination therapy may speed visual recovery, but there remains little evidence for improved long-term visual outcomes from NSAIDs. The last 2 decades have seen increasing data on potential benefits of pretreatment with NSAIDs 1-3 days prior to cataract surgery. Simultaneously, newly approved “dropless” delivery systems hold promise, and clinical trials are ongoing to assess outcomes of such formulations. Conclusions Optimal pharmacologic treatment for inflammation after cataract surgery remains controversial. A consensus definition for clinically significant CME may facilitate the comparison of anti-inflammatory drugs. And there remains a need for well-designed trials examining both topical and extended-release drug-delivery systems to refine the treatment paradigm.

Objectives To assess the quality of diabetic eye disease clinical practice guidelines. Study design and setting A systematic search of diabetic eye disease guidelines was conducted on six online databases and guideline repositories. Four reviewers independently rated quality using the Appraisal of Guidelines, Research, and Evaluation (AGREE II) instrument. Aggregate scores (%) for six domains and overall quality assessment were calculated. A “good quality” guideline was one with ≥60% score for “rigor of development” and in at least two other domains. Results Eighteen guidelines met the inclusion criteria, of which 13 were evidence-based guidelines (involved systematic search and grading of evidence). The median scores (interquartile range (IQR)) for “scope and purpose,” “stakeholder involvement,” “rigor of development,” “clarity of presentation,” “applicability” and “editorial independence” were 73.6% (54.2%–80.6%), 48.6% (29.2%–71.5%), 60.2% (30.9%–78.1%), 86.6% (76.7%–94.4%), 28.6% (18.0%–37.8%) and 60.2% (30.9%–78.1%), respectively. The median overall score (out of 7) of all guidelines was 5.1 (IQR: 3.7–5.8). Evidence-based guidelines scored significantly higher compared to expert-consensus guidelines. Half (n = 9) of the guidelines (all evidence-based) were of “good quality.” Conclusion A wide variation in methodological quality exists among diabetic eyecare guidelines, with nine demonstrating “good quality.” Future iterations of guidelines could improve by appropriately engaging stakeholders, following a rigorous development process, including support for application in clinical practice and ensuring editorial transparency.

PURPOSE This study examines the relationship between fluctuations in central subfield thickness (CST) and visual acuity (VA) in patients with diabetic macular edema (DME) using data from 2 large clinical trials. DESIGN Clinical cohort study using post hoc analysis of clinical trial databases. METHODS Standard deviation (SD) of all recorded CSTs for each patient during the study period were used to quantify the fluctuations in CST. Patients from each protocol were grouped into quartiles based on the CST SD. Eyes with at least 3 CSTs and VA at 1 year were included. The main outcome measures were VA at 1 and 2 years for each protocol, stratified by SD quartile. RESULTS A total of 1197 eyes were included in the analysis. There were significant VA differences based on CST SD quartile for both protocols while adjusting for mean baseline VA, baseline CST, lens status, hemoglobin A1c, and treatment arm. At week 52 in protocol T, the difference between the first and fourth quartiles was -1.61 Early Treatment Diabetic Retinopathy Study letters (95% confidence interval [CI] -3.52 to 0.30, P = .0986). At week 104, this difference was -3.59 letters (95% CI -6.17 to -1.00, P = .0066). In protocol V, at week 52, the difference between the first and fourth quartiles was -3.04 letters (95% CI -4.18 to -1.91, P < .0001). At week 104, this difference was -2.35 letters (95% CI -3.58 to -1.13, P = .0005). CONCLUSION Large fluctuations in CST may portend worse VA outcomes at the 2-year end point in patients with DME.

Background Solar retinopathy is a disease that causes photochemical toxicity in the retinal fovea tissues, leading to an acute decrease of vision. Case presentation This case report is an interventional case of an asymptomatic 17-year-old Caucasian female with a history of suddenly decreased vision due to solar retinopathy. The patient was managed with a custom-made needle injection of triamcinolone acetonide in the suprachoroidal space. Four months post suprachoroidal injection showed an anatomical and functional improvement in the ellipsoid zone layer through optical coherence tomography signal reappearance. In addition, the best-corrected visual acuity had improved from 0.1 to 1.0 on the Snellen chart with the disappearance of the scotoma. However, there was a mild increase in intraocular pressure after this procedure, controlled with topical hypertensive eye drops. Conclusion Suprachoroidal triamcinolone acetonide injection using a custom-made needle showed both functional and anatomical improvement of macular changes post-solar retinopathy, with acceptable safety outcomes in a young female.

To evaluate macular thickness fluctuations and their association with visual acuity outcome in eyes with macular edema (ME) secondary to central (CRVO) or hemiretinal vein occlusion (HRVO) treated initially with intravitreal aflibercept or bevacizumab. Post hoc analysis of 362 patients with ME secondary to CRVO or HRVO initially randomized to six monthly intravitreal injections of aflibercept or bevacizumab. Three spectral domain optical coherence tomography (SD-OCT) central subfield thickness (CST) fluctuation measures were investigated over Months 1–12: standard deviation (SD), number of turning points (T) for each participant, and a measure denoted as Zigzag reflecting the magnitude of alternating ups and downs in a participant’s CST. Main outcome measure is Month 12 visual acuity letter score (VALS). More fluctuations occurred in eyes randomized to bevacizumab than aflibercept: SD (59.98 vs 32.12; p

To determine the characteristics and appearance rate of epiretinal proliferation (ERP) on SD-OCT after surgery for rhegmatogenous retinal detachment (RRD) repair. One hundred eight eyes of 108 patients who underwent one or more surgeries for RRD were enrolled. The eyes with other maculopathies that were directly related to RRD were excluded. Image acquisition was performed with SD-OCT (Heidelberg Engineering, Germany). Clinical charts were reviewed to assess clinical and surgical findings. Statistical analyses were performed using XLSTAT (Assinsoft, Paris, France). ERP was found in 9.3% eyes (n = 10). The mean initial visual acuity (logMAR) was 1.34 ± 0.82 in the ERP group compared to 0.49 ± 0.70 in the non-ERP group. PVR was present in 70.0% and chronic macular edema was found in 80.0% of eyes which developed ERP. The mean number of vitreoretinal surgeries in eyes with ERP was 3.3 ± 1.19 and only 1.44 ± 1.02 in eyes without. Silicone oil was used in 60.0% of eyes which developed ERP compared to 13.9% in the non-ERP group. ERP is a late-onset postoperative finding in eyes with RRD and can occur in absence of macular holes. Overall, ERP is more frequent in eyes with complicated courses of RRD including multiple operations, PVR, usage of silicone oil, and chronic macular edema.

BACKGROUND/OBJECTIVES This meta-analysis investigates the efficacy and safety of intravitreal anti-VEGF injections (IVI) compared to combination laser photocoagulation and IVI (LPC-IVI) in treating macular oedema secondary to retinal vein occlusion (RVO). SUBJECTS/METHODS A literature search of MEDLINE, EMBASE and Cochrane CENTRAL was conducted from inception until March 2021. Randomized controlled trials that reported relevant efficacy and/or safety parameters following LPC-IVI relative to IVI were included. Meta-analysis was conducted with a random effects model. The primary outcome was best-corrected visual acuity (BCVA), while secondary outcomes were central macular thickness (CMT), central retinal thickness (CRT), central subfield thickness (CST), number of IVIs received, and incidence of adverse events. RESULTS A total of 10 studies were included, for which 362 eyes were randomized to LPC-IVI and 365 to IVI. In comparing macular laser photocoagulation with IVI (MLP-IVI) in BRVO patients, no significant differences were seen in final BCVA (p = 0.78) or change in BCVA (p = 0.09) after treatment. Similarly, no significant differences were seen in final CMT (p = 0.54), change in CMT (p = 0.33), final CRT (p = 0.90), change in CRT (p = 0.97), or number of injections required (p = 0.78). The same results were seen in subgroup analyses for macular laser without peripheral laser in BRVO and CRVO patients. Consistent results were observed when considering peripheral LPC-IVI to IVI in BRVO and CRVO. CONCLUSIONS No significant differences were seen between combination MLP-IVI or peripheral LPC-IVI relative to IVI monotherapy for final BCVA or OCT parameters in macular oedema secondary to RVO.

Purpose To report a case of bilateral occlusive vasculitis associated with retinitis pigmentosa (RP). Method Case report. Case report A 34-year male presented with blurred vision in left eye (OS) for two weeks and right eye (OD) for one day. He had night blindness for five years. His best corrected visual acuity (BCVA) was OD 20/63 and OS 20/200. Ophthalmoscopy revealed bilateral RP with OD inflammatory central retinal vein occlusion (CRVO) and OS occlusive vasculitis with bilateral macular edema. Presumed intraocular tuberculosis (IOTB) was suspected based on clinical features, positive Mantoux and high-resolution computed tomography chest findings. Oral steroids and antitubercular therapy (ATT) were started. OD received six intravitreal ranibizumab injections. At his 7-month follow-up, BCVA improved, OD 20/40 and OS 20/80. Conclusion RP rarely can be associated with presumed IOTB. Oral steroids with ATT are helpful; however, in inflammatory CRVO, intravitreal ranibizumab can give good results.

Objective: to compare outcomes of cataract surgery combined with either anti-Vascular Endothelial Growth Factor (anti-VEGF) therapy or dexamethasone implant (DEX) in patients with diabetic macular oedema (DMO). Methods: Pubmed and Embase databases were searched for studies reporting outcomes of diabetic cataract surgery combined with either anti-VEGF or DEX, with a follow-up ≥3 months. The primary outcome was the mean change in central macular thickness (CMT). Mean change in best corrected visual acuity (BCVA) was considered as a secondary outcome. The mean difference between baseline and post-treatment values (MD) with 95%-Confidence Interval (95%CI) was calculated and meta-analyses were performed. Results: ninteen studies were included, 8 in the DEX group and 11 in the anti-VEGF group. A significant reduction of macular thickness was shown in the DEX group at 3 months (MD = −98.35 µm; 95% CI, −147.15/−49.54), while mean CMT change was non-significant in the anti-VEGF group (MD = −21.61 µm; 95% CI, −59.46/16.24; test of group differences, P < 0.001). At 3 months, no difference in visual gain was found between the two groups (P = 0.13). Conclusions: in DMO patients, cataract surgery combined with DEX seems to provide better anatomical outcomes compared with cataract surgery combined with anti-VEGF therapy. However, our evidence was limited by significant heterogeneity. Randomised trials comparing these two different combined approaches are warranted.

Introduction: The aim of the study was to investigate the outcomes of vitrectomy with fovea-sparing internal limiting membrane (ILM) peeling (FSIP) for epiretinal membrane (ERM) foveoschisis based on new optical coherence tomography definitions. Methods: Twenty-three eyes of 22 patients (69.7 ± 9.9 years old) who underwent vitrectomy with FSIP without gas tamponade for ERM foveoschisis were analyzed. All patients underwent follow-up examinations for at least 12 months. In the FSIP technique, the ILM is peeled off in a donut shape, preserving the foveal ILM. The logarithm of the minimal angle of resolution best-corrected visual acuity (BCVA), central macular thickness (CMT), and surgical complications were examined. Results: The BCVA at 12 months improved significantly from baseline (p < 0.001). Baseline ellipsoid zone defects were found in 2 eyes (9%), and all defective eyes had recovered at 12 months. CMT decreased significantly from baseline (p < 0.001). Acute macular edema, full-thickness macular hole, and recurrence of ERM were not observed during follow-up. Discussion/Conclusion: FSIP achieved good visual outcome and retinal morphological change. Moreover, FSIP might avoid acute macular edema in ERM foveoschisis surgery.

Aims To report the effect of simultaneous intravitreal dexamethasone (DEX) and aflibercept for the treatment of diabetic macular edema (DME). Methods This retrospective analysis of an open-label, multicenter, consecutive case series included 102 eyes of 81 patients with DME. Patients were selected into two groups. The control group consisted of 50 eyes treated with aflibercept alone, and the combination group consisted of 52 eyes treated with simultaneous DEX implant and aflibercept injection. The primary endpoints were changes in best-corrected visual acuity (BCVA) and central retinal thickness (CRT) from baseline to month 6. The secondary endpoint was the interval of retreatment. Results Baseline BCVA increased and CRT decreased at 6 months in both groups. Pseudophakic eyes in the combination group exhibited significantly greater BCVA improvement compared with phakic eyes (p = 0.031). Fewer intravitreal treatments were required for eyes treated with combination therapy than for those treated with aflibercept alone (1.56 ± 0.54 vs. 4.04 ± 1.26, p

Purpose To evaluate whether outcome of bevacizumab treatment in the first treated eye can guide the selection of compound for the second treated eye in patients with bilateral diabetic macular edema. Methods Demographic, clinical, and optical coherence tomography data were retrospectively collected from consecutive patients who underwent bevacizumab therapy for bilateral diabetic macular edema. Change in central subfield thickness and visual acuity were evaluated and compared between the first treated eye and second treated eye. Results A total of 66 eyes of 33 patients were included in the study. The mean ± SD follow-up time was 13 ± 5 months. The mean ± SD central subfield thickness at baseline was 464 ± 30 μm in the first treated eye and 461 ± 29 μm in the second treated eye ( p = 0.91). Final central subfield thickness was reduced to 392 ± 27 μm in the first treated eye ( p = 0.01 compared with baseline) and 416 ± 25 μm in the second treated eye ( p = 0.03 compared with baseline). Using ≥5% or ≥10% reduction of central subfield thickness as diagnostic criteria to predict similar magnitude of thickness reduction in the first treated eye yielded a positive and negative predictive value ranging from 46% to 81%, and sensitivity and specificity ranging from 54% to 84%. Regression models did not show correlation between central subfield thickness reduction in first treated eye and the second treated eye at the end of follow-up. Conclusions Bevacizumab therapy reduced macular thickness in both eyes in bilateral diabetic macular edema. Treatment outcome of the first treated eye could not predict the outcome of the second treated eye. Particularly, failure to reduce central subfield thickness in the first treated eye does not preclude a favorable response to bevacizumab therapy in the second eye.

To identify the eyes with macular edema (ME) due to a branch retinal vein occlusion (BRVO) that have good visual acuity during the continuous anti-vascular endothelial growth factor (anti-VEGF) treatment based on the patients’ clinical information and optical coherence tomography (OCT) images by using machine learning. Sixty-six eyes of 66 patients received 1 anti-VEGF injection followed by repeated injections in the pro re nata (PRN) regimen for 12 months. The patients were divided into two groups: those with and those without good vision during the 1-year experimental period. Handcraft features were defined from the OCT images at the time of the first resolution of the ME. Variables with a significant difference between the groups were used as explanatory variables. A classifier was created with handcrafted features based on a support vector machine (SVM) that adjusted parameters for increasing maximal precision. The age, best-corrected visual acuity (BCVA) at the baseline, BCVA at the first resolution of the ME, integrity and reflectivity of the external limiting membrane (ELM), the ellipsoid zone (EZ), and area of the outer segments of the photoreceptors were selected as explanatory variables. The classification performance was 0.806 for accuracy, 0.768 for precision, 0.772 for recall, and 0.752 for the F-measure. The use of the SVM of the patient’s clinical information and OCT images can be helpful for determining the prognosis of the BCVA during continued pro re nata anti-VEGF treatment in eyes with ME associated with BRVO.

Purpose The intravitreal dexamethasone implant (DEX-I) is an alternative to anti-VEGF for the first-line treatment of diabetic macular oedema (DME). However, several questions remain regarding its routine use and its place in certain situations not always specified in current recommendations. A national consensus approach was, therefore, initiated by French retinal experts. Methods An iterative Delphi consensus approach was used. A steering committee (SC) of seven experts analysed data from the literature to formulate statements divided into five key areas of treatment. These statements were submitted to the independent and anonymous electronic vote of 87 French retina experts among whom 39 expressed their opinion and therefore constituted the voting panel. Results After two rounds of voting, 22 and 7 of 38 statements received a strong consensus and a good consensus, respectively. The consensus level was higher for statements regarding first-line indications and safety of DEX-I compared to those regarding efficacy assessment, reprocessing time or pathophysiological biomarkers. The panellists recommended the preferential use of DEX-I for patients with limited availability for multiple injections, those who needed to undergo cataract surgery or who had a recent cardiovascular history, and as a therapeutic alternative to anti-VEGF in patients with a history of vitrectomy, retinal serous detachment, hyper-reflective points or dry exudates in optical coherence tomography (OCT). However, some statements proposed by SC experts were not validated. Conclusion This study provides some key recommendations to clinicians treating diabetic macular oedema, which may be useful when using intravitreal dexamethasone implants in daily practice.

Purpose To evaluate the microvascular changes in the macular and peripapillary area after intravitreal dexamethasone implant in diabetic macular edema (DME) Material and Methods We included 31 eyes of 31 patients treated with a single dose dexamethasone implant for DME. All subjects underwent swept-source optical coherence tomography (OCT) and OCT angiography imaging before (T0), and one month (T1), two months (T2), and four months (T4) after dexamethasone injection. The foveal avascular zone (FAZ) area of superficial and deep capillary plexus (SCP and DCP) was calculated by delineating the FAZ border using the measurement tool of the device. The vessel density (VD) of SCP and DCP and choriocapillaris (CC) in the macular and peripapillary area were automatically calculated. Results There was an insignificant reduction in FAZ area measurements of SCP after dexamethasone injection in DME patients (p = 0.846). The FAZ area of DCP were significantly smaller compared to T0 measurements at T1, T2, and T4 (p = 0.013, p = 0.031, and p = 0.029, respectively). The mean average parafoveal VD measurements were significantly decreased after dexamethasone injection in SCP and DCP (p = 0.004, p = 0.005). The peripapillary VD in retinal capillary plexuses and choriocapillaris showed no significant difference after dexamethasone injection. Conclusion Intravitreal dexamethasone leads to a significant FAZ area decrease in DCP with a reduction in parafoveal VD measurements. In addition, no significant VD changes were observed in the peripapillary area after dexamethasone. These findings indicate that dexamethasone may improve macular ischemia with no significant effects on peripapillary microvasculature in DME patients.

CLINICAL RELEVANCE Diabetic macular oedema (DME) is a significant cause of visual impairment and inflammation plays an important role in its pathophysiology. BACKGROUND This study evaluates the diagnostic value of systemic immune-inflammation index (SII) in the occurrence of DME in patients with non-proliferative diabetic retinopathy. METHODS In this prospective study, the SII was applied to 150 consecutive patients with non-proliferative diabetic retinopathy. The relationship between the SII and the occurrence of DME was examined. Patients with DME were also divided into two subgroups according to the presence of accompanying sub-retinal fluid. The SII value was calculated as follows: platelet count × (neutrophil/lymphocyte). The risk factors for DME were evaluated using multivariate logistic regression analysis. A receiver operating characteristic (ROC) curve analysis of SII for predicting DME was performed. RESULTS Patients with DME had significantly higher levels of SII than those without DME (599.7 ± 279.2 and 464. 9 ± 172.2, respectively, p

Purpose of review Nearly 20 years ago, vascular endothelial growth factor (VEGF)inhibitors (VEGFi) were adapted from systemic use from antiangiogenesis roles to intravitreal uses. Initially bevacizumab a murine immunoglobulin was injected 'off label' as a treatment for diabetic macular edema and age-related macular degeneration. Throughout the following decade aflibercept and finally ranibizumab were adapted and obtained Food and Drug Administration approval for intravitreal use. Initially systemic absorption was thought to be quite low after intravitreal injections and was quoted as being 200-fold lower than levels postulated to induce significant VEGF inhibition. Pharmacodynamic studies obtained in 2014 and again in 2017 revealed significant systemic absorption and detectable VEGF inhibition, this has since been confirmed in multiple subsequent studies. Recent findings A few case reports of renal dysfunction and glomerular disease related to VEGFi were initially identified. Mixed findings on effects on blood pressure were noted in studies. More recently, 32 cases of de-novo glomerular disease and/or proteinuria exacerbation were identified. New studies have corroborated increased blood pressure, proteinuria exacerbation in patients with pre-existing nephrotic syndrome, and systemic VEGF depletion. Further, the most common lesion of systemic VEGFi nephrotoxicity, thrombotic microangiopathy, has recently been reported by our group. Summary We will review the pharmacokinetic, translational, and epidemiological data that year upon year establish the finite-yet real risk of intravitreal VEGFi.

OBJECTIVE To investigate CYP4V2 gene variants and ocular clinical characteristics of Bietti corneoretinal crystalline dystrophy in China so as to provide more references for genotype and phenotype of BCD. METHODS Sixteen Chinese probands were recruited in Beijing Tongren Hospital in a retrospective study. All patients underwent CYP4V2 gene detection and ophthalmic clinical examinations. RESULTS CYP4V2 gene variants were detected in all patients. Eight variants were identified, and the most common one was c.802-8_810del17bpinsGC. Onset age of BCD was from 12 to 44 years, and the first symptoms mostly were decreased visual acuity or night blindness. Corneal crystalline depositions were observed in all patients and were found not only in epithelium and superficial stroma near the limbus but also in corneal endothelium. OCT showed atrophy of RPE in all patients, outer retinal tubulation in ten patients, macular edema in four patients, macular hole in three patients with one accompanied with retinal detachment, and choroidal neovascularization in one patient. CONCLUSION CYP4V2 gene variants were detected in all patients consistent with the genetic locus homogeneity of BCD, and c.802-8_810del17bpinsGC was the most common mutation. Corneal crystalline depositions were observed in all patients, which may be features of BCD and helpful for the diagnosis of BCD patients, especially those in the advanced stage without typical fundus crystalline depositions or without gene detection. However, considerable phenotypic variability was detected. Corneal crystalline deposits were observed not only in epithelium and superficial stroma but also in endothelium, which has not been reported before. This may provide further evidence for the variable phenotypic expression between affected individuals.

Purpose Estimates of diabetic eye disease in American Indian and Alaska Natives (AI/AN) vary over time, region, and methods. This article reports recent prevalence of diabetic retinopathy (DR) and diabetic macular edema (DME) in AI/AN served by the Indian Health Services' (IHS) teleophthalmology program, as identified using ultrawide field imaging (UWFI). Methods This was a retrospective analysis of 2016-2019 clinical data (n = 53,900). UWF images were acquired by certified imagers using a validated protocol, and graded by licensed, certified optometrists supervised by an ophthalmologist. Graders evaluated the extent/severity of retinal lesions in comparison to standard photographs. DR lesions predominantly in any peripheral field were considered "predominantly peripheral lesions" (PPL). The analyses calculated prevalence of any DR, any DME, DR and DME severity, sight-threatening disease, and PPL. Results Patients averaged 56 years of age with a 68 mmol/mol A1c and 55% had had diabetes for 5+ years. Prevalence of any DR, any DME, and sight-threatening disease was 28.6%, 3.0%, and 3.0%. In patients with mild nonproliferative DR, PPL was seen in 25.3%. PPL suggested a more severe level of DR in 8.7% of patients. DR increased with age. DME decreased with age. Males and patients in the Nashville IHS area had more diabetic eye disease. Conclusion AI/AN have a high burden of diabetes and its complications. The IHS is resource-constrained, making accurate disease estimates necessary for resource allocation and budget justifications to Congress. These data update the estimates of diabetic eye disease in Indian Country and suggest that UWFI identifies early DR.

To distinguish DR retinal one device is utilized called Optical Coherence Tomography (OCT). So to break down hard exudates (HEs) and their antecedents in patients with diabetic retinopathy (DR) by utilizing Optical Coherence Tomography (OCT) pictures is fundamental. Hard Exudates (HEs) are one kind of principle sign of DR. It is the back shaft of an eye with macular edema. Modified acknowledgment of HE from the retinal picture is a critical development for the area of DR. HE is an essential in the eye for those having diabetes. This Hard Exudates can provoke visual weakness if not managed before all else stages. This errand is a piece of the whole pattern of perceiving the hard exudates in their starting stages. Concentrate fundamental features which can help us in the recognizable proof of the HE. Therefore, HE area is indispensable for clinical discoveries. Consequently, HE location is vital for clinical finding.

We present the outcomes of 2 cases of cystoid macular edema, complicating an eccentric macular hole, treated with argon laser therapy to barricade the macular hole., Purpose: To report the outcomes of laser therapy to barricade eccentric full-thickness macular hole with associated cystoid macular edema. Methods: We report two patients who developed an eccentric full-thickness macular hole with persistent cystoid macular edema after pars plan vitrectomy with and without internal limiting membrane peel for epiretinal membrane and the results of argon laser therapy. Results: Barricade argon laser therapy was applied concentric to the full-thickness macular hole. Associated cystoid macular edema was noted to resolve within 1 to 3 months of therapy in both cases. Conclusion: Barricade laser therapy surrounding a macular hole can lead to resolution of associated cystoid macular edema. Pathogenic mechanisms to explain this favorable outcome are discussed.
