The current evidence on whether annual diabetic retinopathy (DR) screening intervals can be extended was reviewed. A systematic review protocol was followed (PROSPERO ID: CRD42022359590). Original longitudinal articles that specifically assessed DR screening intervals were in English and collected data after 2000 were included. Two reviewers independently conducted the search and reviewed the articles for quality and relevant information. The heterogeneity of the data meant that a meta‐analysis was not appropriate. Twelve publications were included. Studies were of good quality and many used data from DR screening programs. Studies fit into three categories; those that assessed specific DR screening intervals, those that determined optimal DR screening intervals and those that developed/assessed DR screening risk equations. For those with type 2 diabetes, extending screening intervals to 3‐ to 4‐yearly in those with no baseline DR appeared safe. DR risk equations considered clinical factors and allocated those at lower risk of DR progression screening intervals of up to five years. Those with baseline DR or type 1 diabetes appeared to have a higher risk of progression to STDR and needed more frequent screening. DR screening intervals can be extended to 3–5 yearly in certain circumstances. These include patients with type 2 diabetes and no current DR, and those who have optimal management of other risk factors such as glucose and blood pressure. [ABSTRACT FROM AUTHOR]

Abstract Background The aim was to study aqueous humour inflammatory mediators’ levels in a cohort of Egyptian patients with diabetic macular oedema (DMO). Methods This was a case-control prospective study conducted on 2 groups: 25 eyes of 22 (11 females) patients seeking treatment for DMO as patients group, and 10 eyes of 10 (4 females) cataract patients as a control group. Aqueous humour was aspirated before intravitreal injection (patients’ group) or cataract surgery (control group). Inflammatory mediators in aqueous humour were measured using a multiplex bead immunoassay kit of 27 pre-mixed cytokines. Results Eotaxin, interferon gamma-induced protein 10 (IP-10), monocyte chemoattractant protein-1 (MCP-1/CCL2) and interleukin-8 (IL-8/CXCL8) were found significantly higher in patients’ group compared to control group (p = 0.043, 0.037, 0.001, 0.015 respectively). On the contrary, interferon-gamma (IFN-gamma) and granulocyte colony-stimulating factor (G-CSF) were found significantly higher in control group than patients’ group (p = 0.003, 0.019 respectively). Basic fibroblast growth factor (Basic-FGF/FGF-2) and interleukin-1 receptor antagonist (IL-1ra) were found higher (but not statistically significant) in controls (p = 0.100 and 0.070 respectively). Additionally, a negative and significant correlation was found between Eotaxin level in aqueous humour and central macular thickness. Conclusions Some mediators might be implicated in the pathogenesis of DMO either augmenting or suppressing role. Eotaxin, IP-10, MCP-1 and IL-8 might have a role in cases not responding to standard anti-vascular endothelial growth factor (VEGF) therapy. IL-1ra might have a protective role; therefore, the effectiveness of intravitreal injection of IL-1ra homologue needs to be studied in future clinical trials.

Se identificaron preguntas clínicas de investigación relevantes para el objetivo del documento, reformuladas en formato PICO (paciente, intervención, comparación, outcome o desenlace) por un panel de expertos seleccionados en base a su experiencia en el área. Se realizó una revisión sistemática de la evidencia, graduándose de acuerdo a los criterios Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Subsecuentemente, se formularon las recomendaciones. Se seleccionaron tres preguntas PICO, referentes a uveítis anteriores, no anteriores y complicadas con edema macular. Se formularon un total de 19 recomendaciones con base en la evidencia encontrada y/o en el consenso de expertos. Se presenta el primer documento oficial de la Sociedad Española de Reumatología de recomendaciones para el tratamiento de las uveítis. Pueden aplicarse directamente al sistema sanitario español como herramienta de ayuda y homogenización terapéutica. To develop evidence-based expert-consensus recommendations for the management of non-infectious, non-neoplastic, non-demyelinating disease associated uveitis. Clinical research questions relevant to the objective of the document were identified, and reformulated into PICO format (patient, intervention, comparison, outcome) by a panel of experts selected based on their experience in the field. A systematic review of the available evidence was conducted, and evidence was graded according to GRADE (Grading of Recommendations Assessment, Development, and Evaluation) criteria. Subsequently, recommendations were developed. Three PICO questions were constructed referring to uveitis anterior, non-anterior and complicated with macular edema. A total of 19 recommendations were formulated, based on the evidence found and/or expert consensus. Here we present the first official recommendations of the Spanish Society of Rheumatology for the treatment of non-infectious and non-demyelinating disease associated uveitis. They can be directly applied to the Spanish healthcare system as a tool for assistance and therapeutic homogenisation. [ABSTRACT FROM AUTHOR]

Purpose: This study assessed the effectiveness of the 0.19-mg fluocinolone acetonide (FAc) implant by multimodal measurements in patients with non-infectious uveitis (NIU) in a real-world setting in Spain. Methods: A prospective study of patients who had NIU including uveitic macular oedema (UME) with ≥ 12 months follow-up was done. Exclusion criteria include infectious uveitis and uncontrolled glaucoma or ocular hypertension requiring more than 2 medications. Effectiveness was assessed using a multicomponent outcome measure that included nine outcomes. Effectiveness was defined as all components being met at every timepoint. Secondary outcome measures were onset or progression of glaucoma and investigator-reported adverse events. Results: Twenty-six eyes from 22 patients were included, with 96.2% having an indication including UME. During the 12-month study, the FAc implant was effective in 15 (57.7%) eyes, reaching effectiveness as soon as 2 weeks post-implantation. Mean best-corrected visual acuity and mean central macular thickness (CMT) were significantly improved vs. baseline at all timepoints (all comparisons p < 0.01). During the 12-month study, inflammation markers (anterior chamber cells and vitreous haze) had also significantly declined. Factors predicting effectiveness at month 12 were systemic corticosteroid dose pre-FAc, higher immunomodulatory therapy (IMT) load at baseline and thicker retinal nerve fibre layer (RNFL) at baseline (all p < 0.05). Factors predicting failure were male gender, thinner RNFL at baseline and treatment ineffectiveness at 1 month (all p < 0.05). In parallel, corticosteroid and IMT use also declined significantly. No significant increase in IOP was detected. Conclusion: The FAc implant is safe and effective at treating NIU over 12 months in a real-world setting in Spain. [ABSTRACT FROM AUTHOR]

Background: Retinal vein occlusion is the second most common retinal vascular disease after diabetic retinopathy. Branch retinal venous occlusion (BRVO) occurs the occlusion of one of the branches of the retinal vein. The occlusion occurs mostly at arteriovenous crossing and more frequent in upper temporal retinal veins. Patients and Methods: In the current study, randomized control study was conducted on 2 groups divided into 27 eyes (Ranibizumab alone), 27 eyes (Ranibizumab and Targeted retinal laser). Results: The BRVO is investigated by FFA and OCT-Macula and macular edema is measured by OCT-Macula. And the current result shows highly statistically significant improvement in visual acuity and reducing macular edema (decrease foveal thickness)with P value

Introduction: Post Fever Retinitis (PFR) is an infectious or parainfectious uveitis presenting with visual impairment after a fever episode. The condition can cause potential visual impairment in these patients. There is no national guideline for treatment of PFR. Hence, there is a need to study the clinical features and visual outcomes with the use of corticosteroid therapy. Aim: To describe the clinical features of patients presenting with PFR and visual outcome with the oral corticosteroid therapy. Materials and Methods: This retrospective study conducted in the Outpatient Department (OPD) of Ophthalmology at SDM College of Medical Sciences and Hospital, Dharwad, Karnataka, India. The duration of the study was 35 months, from January 2019 to December 2021. A total of 23 eyes of 13 patients treated with oral corticosteroids were included. Data collected included patients' demographic details including name, age, sex, hospital identification number, duration of vision loss, detailed ophthalmic examination findings, including visual acuity testing with Snellen's chart, slit lamp examination findings and fundus examination findings including detailed fundus drawings, Optical Coherence Tomogram (OCT) and fundus photographs. Visual Acuity (VA) at the time of presentation and after steroid therapy were recorded. Data was entered in microsoft excel spreadsheet and descriptive analysis was done. Results: Age of the study participants ranged from 15 years to 52 years with an average of 29.6 years. A total of 23 eyes of 13 patients were included in the present study. At the time of presentation, two eyes had visual acuity better than 6/12 on Snellen's chart. Five eyes had mild vision impairment, five eyes had moderate vision impairment and eleven eyes had vision <3/60, according to the visual impairment classification of World Health Organisation (WHO). Macular oedema was the other most common finding seen in 12 (52.17%) eyes. All the patients showed beginning of resolution of retinitis by 2-3 weeks after starting oral corticosteroids. A total of 23 eyes, 8 (34.7%) eyes recovered vision >6/12, out of which 6 eyes (26.08%) recovered with 6/6 vision. Conclusion: PFR affects predominantly young immunocompetent individuals. Treatment outcomes with oral steroids is found to be satisfactory. [ABSTRACT FROM AUTHOR]

Background: Central retinal vein occlusion and branch retinal vein occlusion are common causes of visual loss due to associated macular oedema. The aim of this review was to assess the effectiveness of interventions improving vision and treating macular oedema in central retinal vein occlusion and branch retinal vein occlusion. Methods: Medical search engines and clinical trial registries were systematically searched. Randomised clinical trials with ≥90 eyes and real‐world outcome studies with ≥100 eyes each with ≥6 months follow‐up were included. Results: There were 11 randomised controlled trials evaluating treatments for central retinal vein occlusion which met the inclusion criteria and 10 for branch retinal vein occlusion. There were 10 real world outcome studies of central retinal vein occlusion and 5 real world outcome studies of branch retinal vein occlusion. Meta‐analysis was performed on studies that met the defined inclusion criteria. Main outcomes were change in visual acuity at 6‐, 12‐, 24‐ and 36 months by treatment. Conclusions: Intravitreal anti‐vascular endothelial derived growth factor is recommended as first line treatment over intravitreal corticosteroid due to its effectiveness and lower rate of ocular adverse events. Best outcomes are achieved when intravitreal treatment is started early. Macular laser may have an adjunctive role in branch retina vein occlusion but not central retinal vein occlusion.

To suggest a unique missense variant candidate based on long‐term ophthalmological changes and associated systemic signs described in five patients from two unrelated families affected by an autosomal dominant multi‐systemic disorder including Retinal dystrophy, Optic nerve oedema, Splenomegaly, Anhidrosis and migraine Headaches, called ROSAH syndrome, related to a unique missense variant in ALPK1 gene. Observational longitudinal follow‐up study of unrelated families. Clinical analysis of ophthalmological and systemic examinations was performed, followed by genetic analysis, including targeted Next Generation Sequencing (NGS) and Whole‐Genome Sequencing (WGS). The ophthalmological phenotype showed extensive optic nerve swelling associated with early macular oedema and vascular leakage. The main associated systemic manifestations were recurrent fever, splenomegaly, anhidrosis, mild cytopenia, anicocytosis and hypersegmented polynuclear cells. WGS, shortened in the second family by the gene candidate suggestion, revealed in all patients the heterozygous missense variant c.710C>T; p.(Thr237Met) in ALPK1. The primary morbidity in ROSAH syndrome in this cohort appeared ophthalmological. Comprehensive, detailed phenotype changes aided by the advancement in genetic testing could allow an early genetic diagnosis of ROSAH syndrome and targeted treatment. The unique missense variant may be suggested as a target of gene correction therapy. [ABSTRACT FROM AUTHOR]

Background: The accumulation of fluid between the retinal layers is called retinal or macular oedema, while intraretinal oedema, or macular oedema, refers to fluid accumulation directly within the retina. The purpose of the study was to evaluate the effects of intravitreal injections of bevacizumab on intraocular pressure (IOP) in Non-Glaucomatous patients with Macular Oedema. Methods: A pre-and post-interventional study was conducted. 220 patients were studied utilizing a non-probability, consecutive sampling method. Open Epi software was used to determine the sample size. The Department of Ophthalmology at Islamabad's Tertiary Care Hospital hosted the study, which lasted six months. Results: The study's participants ranged in age from 30 to 60, with a mean age of 50.38±6.53 years. Male to female ratio of these 220 patients was 1:1.6, with 86 (39.09%) men and 134 (60.91%) women. The mean IOP at baseline was 11.57±1.42 mmHg, and the mean IOP one month after the injection was 12.81±1.18 mmHg, with a mean change in IOP of 1.24±0.87 mmHg. Conclusion: This study found that non-glaucomatous patients with macular oedema experienced a high mean change in intraocular pressure (IOP) after intravitreal Avastin. [ABSTRACT FROM AUTHOR]

Diabetic retinopathy (DR) have been taking a leading position among retinal disorders, causing a persistent and significant decrease in visual functions. The base of the disease is a retinal vascular microangiopathy, which induces a tissue ischemia and excessive production of vascular endothelial growth factors. The main method of treatment for this pathology is a laser photocoagulation. However, it is not always possible to perform appropriate laser photocoagulation, by that limiting its efficacy (cases of hard cataract and hemophthalmos). In addition, this type of treatment might have a number of serious complications, such as macular oedema, recurrent vitreous hemorrhages, the occurrence of fibrosis, atrophic changes in the retina, which leads to a decline in visual acuity and contrast sensitivity, worsening the visual field. Over the past 10 years, vascular endothelial growth factor inhibitors have been introduced into clinical practice, and showed their benefits in the treatment of disorders leading to a pathological angiogenesis. But due to the limited number of systematic observations, assessing the impact of these drugs, is necessary to investigate their efficacy and safety in patients with proliferative DR, in order to develop indications for their use. The purpose of the review is evaluation of the effect of vascular endothelial growth factor inhibitors on active neovascularization in patients with proliferative diabetic retinopathy. There is a literature of international clinical guidelines, randomized clinical trials with a varying level of evidence, articles and publications by groups of authors in the article.

Systemic administration of agents that inhibit vascular endothelial growth factor (VEGF) and therefore vascular proliferation is often used to treat various cancers. However, these agents are associated with a number of side effects, including proteinuria and renal injury. Intravitreal injection of anti‐VEGF agents has become the cornerstone of macular disease treatment. Since these agents cross the blood‐retina barrier and enter the circulation, systemic side effects have been reported. We report the novel case of a 57‐year‐old patient who presented with macular oedema secondary to central retinal vein occlusion, underwent three monthly loading‐dose injections with the anti‐VEGF agent ranibizumab, and 2 weeks after the second injection presented with biopsy‐verified membranoproliferative glomerulonephritis. Twelve weeks after presenting with renal failure and 10 weeks after his last anti‐VEGF injection, the patient demonstrated spontaneous recovery of his kidney function. The patient had a history that promoted renal fragility, including hypertension, liver transplantation 6 years earlier for alcohol‐related cirrhosis and new‐onset diabetes mellitus after transplant. Our literature review and case suggest that although adverse renal events after intravitreal anti‐VEGF injections are very rare, ophthalmologists and nephrologists should be aware of this risk.

Purpose: To evaluate treatment efficacy in diabetic macular oedema (DME) comparing a study population receiving combined intravitreal vascular endothelial growth factor (VEGF) inhibition and focal/grid photocoagulation with a matched, real‐world population receiving standard of care treatment. Methods: In an exploratory study, we included 43 eyes from 32 patients from a previously published study as well as 46 eyes from 38 standard‐of‐care patients. The study population had received a loading dose of three monthly aflibercept injections followed by focal/grid photocoagulation and additional aflibercept pro re nata. Principal measurements at 12 months were numbers of intravitreal injections, best corrected visual acuity (BCVA) and central retinal thickness (CRT). Results: At baseline, there were no differences between groups regarding age, sex, body mass index, haemoglobin A1C, systolic pressure or type of diabetes, but the study population had a higher diastolic pressure (81.6 versus 72.1 mmHg, p = 0.03) and a lower duration of diabetes (12.3 versus 23.2 years, p = 0.03). At month 12, patients in the study group had a higher visual acuity (79.6 versus 74.3 ETDRS letters, p = 0.03), despite having received fewer aflibercept injections (4.4 versus 5.9, p < 0.01) with a higher likelihood of having only received the three mandatory injections in the loading phase (39.5% versus 13.0%, p = 0.01). Conclusion: In comparison to a matched, real‐world DME‐population, patients in combined treatment with intravitreal aflibercept and postloading focal/grid photocoagulation obtained a better functional outcome despite having received fewer intravitreal injections. Future randomized studies are needed to evaluate the long‐term efficacy of this combined treatment regimen. [ABSTRACT FROM AUTHOR]

Purpose: Angiostatic agents have proven effective in the treatment of macular oedema in patients with branch retinal vein occlusion (BRVO). However, treatment is inconvenient and expensive, and novel treatment regimens are warranted. We aimed to evaluate if combination treatment of navigated central retinal laser and aflibercept lowered the treatment burden in these patients. Methods: Treatment‐naïve patients with BRVO and macular oedema were included at two centres and randomized 1:1 to three monthly injections of 2.0 mg aflibercept with (Group A) or without (Group B) navigated central laser, followed by aflibercept as needed from month 4 through 12. Re‐treatment need was evaluated, and secondary endpoints included functional and anatomical outcomes and safety evaluated by retinal microperimetry. Results: We evaluated 41 eyes of 41 patients with a mean age of 69.6 years. Baseline median best‐corrected visual acuity (BCVA) was 70.0 letters, and median central retinal thickness (CRT) was 502 μm with no difference between Groups A (n = 21) and B (n = 20). Percentage of patients needing re‐treatment after month three was 71% and 80% (p = 0.72). At month 12, groups did not differ in number of injections after loading (1 versus 2, p = 0.43), change in BCVA (+12.8 versus +15.1 letters, p = 0.48), CRT (−195 versus −181 μm, p = 0.82), or retinal sensitivity (+3.3 versus +4.1 dB, p = 0.67). Conclusion: In treatment‐naïve BRVO patients, addition of navigated central laser to aflibercept did not lower treatment burden or affect functional or anatomical outcomes. A low number of intravitreal injections were needed for successful outcome in both treatment arms. [ABSTRACT FROM AUTHOR]

Peroxisomal biogenesis disorders (PBDs) are a heterogeneous group of genetic diseases. Multiple peroxisomal pathways are impaired, and very long chain fatty acids (VLCFA) are the first line biomarkers for the diagnosis. The clinical presentation of PBDs may range from severe, lethal multisystemic disorders to milder, late-onset disease. The vast majority of PBDs belong to Zellweger Spectrum Disordes (ZSDs) and represents a continuum of overlapping clinical symptoms, with Zellweger syndrome being the most severe and Heimler syndrome the less severe disease. Mild clinical conditions frequently present normal or slight biochemical alterations, making the diagnosis of these patients challenging. In the present study we used a combined WES and RNA-seq strategy to diagnose a patient presenting with retinal dystrophy as the main clinical symptom. Results showed the patient was compound heterozygous for mutations in PEX1. VLCFA were normal, but retrospective analysis of lysosphosphatidylcholines (LPC) containing C22:0–C26:0 species was altered. This simple test could avoid the diagnostic odyssey of patients with mild phenotype, such as the individual described here, who was diagnosed very late in adult life. We provide functional data in cell line models that may explain the mild phenotype of the patient by demonstrating the hypomorphic nature of a deep intronic variant altering PEX1 mRNA processing.

Background and Aim: Macular oedema (ME) occurs in a variety of pathological conditions and accounts for different degrees of vision loss. Early detection of ME is therefore critical for diagnosis and management. Optical Coherence Tomography (OCT) is particularly useful and accurate for measuring retinal nerve fiber layer (RNFL) thickness and macular thickness. This study is undertaken to evaluate the quantitative changes in macular thickness using spectral domain optical coherence tomography in diabetic patients undergoing cataract surgery pre and post operatively and its relation with diabetic retinopathy. Material and Methods: Study participants included 100 diabetic patients irrespective of presence or absence of retinopathy who underwent cataract surgery. Each eye underwent fundus examination with indirect ophthalmoscopy and OCT of macula i.e.,preoperatively and at postoperatively at day 1, 1 week, 4 weeks and at 12 weeks. Best-corrected visual acuity (BCVA) was recorded at each visit. Results: Visual acuity improved postoperatively at 4th and 12th week after small incision cataract surgery to 6/12 and 6/9 in majority of the patients. Post operatively 1 month 75% patients achieved vision of 6/6– 6/12. Mean values of central subfield macular thickness at preoperatively was 268.9 µm which increased to 278.2 µm at postoperative day 1, 281.6 µm at postoperative 1 week, 286.1 µm at postoperative 4 weeks and 297.2 µm at postoperative 12 weeks. Conclusion: There was no difference in median macular thickness between the groups, and no cases in either group had an increase in macular thickness to reach this threshold. diabetic macular edema generally worsens after cataract surgery, and that the worsening of macular edema is more prominent in eyes with DR.

Background: Macular oedema is a final common pathway of a multitude of both ocular and systemic insults. This study was conducted to evaluate the short-term efficacy and safety of intraocular Ranibizumab in patients with macular oedema in a 'real-world' setting in Pakistan. Methods: A prospective multicenter study conducted at Amanat Eye Hospitals in Islamabad and Rawalpindi from 1st August 2018 to 1st November 2019. Forty-four eyes of 34 patients with macular oedema were treated with monthly intravitreal Ranibizumab (Patizra®) injections for three consecutive months. Best-corrected visual acuity (BCVA), and optical coherence tomography (OCT) parameters including central retinal thickness (CRT) and macular volume were assessed prior to the injections and then 4 weeks post the final injection and compared. Results: BCVA improved from logMAR 0.61±0.40 at baseline to 0.27±0.35 four weeks after the third intravitreal injection. CRT decreased from 428.54±187.06µm at baseline to 364.50±170.49 μm. Macular volume showed a non-significant decrease from 9.97±3.19 mm3 at baseline to 9.22±2.68 mm³ four weeks after the third intravitreal injection. No systemic or ocular complications were observed during the course of the study. Conclusion: Treatment with intravitreal Patizra® injections was found safe and resulted in clinically and statistically significant improvement in visual acuity and the SD-OCT parameter of central retinal thickness in patients with macular oedema secondary to various retinal pathologies. There was no significant decrease in the macular volume. [ABSTRACT FROM AUTHOR]

Faricimab is a new drug approved for the treatment of neovascular age-related macular degeneration (AMD) and diabetic macular edema. It is the first bispecific monoclonal antibody for intraocular use. Faricimab inhibits pathological angiogenesis and reduces vascular permeability and inflammation in the eye. Clinical trials have shown that faricimab is noninferior to aflibercept, another VEGF inhibitor, in improving visual acuity in patients with AMD and diabetic macular edema. The drug has a similar safety profile to aflibercept, with mild to moderate ocular adverse events being the most commonly reported. Faricimab has the potential to extend treatment intervals, reducing the burden on patients. [Extracted from the article]

(1) Background: we aimed to evaluate choroidal vascularity change in eyes with central and branch retinal vein occlusion (RVO). (2) Methods: in this retrospective cross-sectional study, we reviewed the records of 47 patients with recent-onset, naïve, unilateral retinal vein occlusion. Enhanced-depth imaging optical coherence tomography scans were binarized using the ImageJ software; luminal area (LA) and total choroidal area (TCA) were measured. The choroidal vascularity index (CVI) was calculated as the proportion of LA to TCA. Depending on the pattern of macular oedema, eyes were classified as having no macular oedema (nME), cystoid macular oedema (CME), cystoid macular oedema with serous retinal detachment (mixed). (3) Results: CVI, TCA and LA were greater in eyes with RVO than in fellow, unaffected eyes. No difference was found between central and branch RVO except for central macular thickness (CMT). When compared with controls, eyes with CME presented a significant increase in subfoveal choroidal thickness, CMT, TCA, LA and CVI; eyes with mixed macular oedema had greater CMT and CVI than contralateral eyes; no significant differences in any of the considered parameters were observed in eyes with nME. (4) Conclusions: The results suggest that RVO alters the vascularity of the choroid that varies according to the type of macular oedema. [ABSTRACT FROM AUTHOR]

Purpose: To determine which demographic and clinical characteristics are predictive of vision‐related quality of life (VrQoL) and quality of life (QoL) in patients with macular oedema receiving intravitreal anti‐vascular endothelial growth factor (VEGF) treatment. Methods: Vision‐related quality of life (VrQoL) and quality of life (QoL) were measured in 712 patients with retinal exudative disease receiving anti‐VEGF treatment at baseline, 6 and 12 months. VrQoL was measured using an item‐response theory based 47‐question item bank (EyeQ), whereas QoL was measured using the EuroQol Five Dimensions (EQ‐5D) questionnaire. The EQ‐5D score was dichotomized into a perfect score of 1 and a suboptimal score of <1. Demographic and clinical patient characteristics were considered as possible predictors of (Vr)QoL. Prediction models for (Vr)QoL were created with linear mixed models and generalised estimating equations, using a forward selection procedure. Results: A worse VrQoL was predicted by poorer LogMAR visual acuity of the better eye, female sex, single civil status, older age, longer length of anti‐VEGF treatment at baseline and the presence of non‐ocular and ocular comorbidities. Suboptimal EQ‐5D scores were predicted by poorer LogMAR visual acuity of the better eye, female sex, single civil status, older age, the presence of non‐ocular comorbidities and a lower educational background. Conclusions: Along with visual acuity of the better eye, which is the main factor used in clinical decision making, other patient characteristics should also be considered for the risk assessment of (Vr)QoL, such as sex, age, civil status, comorbidities and length of anti‐VEGF treatment.

Aims: To evaluate the prevalence and severity of diabetic retinopathy including macular oedema in pregnant women with diabetes and to identify women in whom the frequency of retinal screening can be reduced to minimize the burden of health care visits. Methods: A cohort study of 348 women with pre‐existing diabetes were routinely screened with retinal photo in early (12 weeks) and late pregnancy (27 weeks). Diabetic retinopathy was classified in five stages in accordance with National Danish Guidelines based on the eye with the highest retinopathy level. Sight‐threatening retinopathy was defined as the presence of proliferative retinopathy and/or clinically significant macular oedema (CSMO). Results: Retinopathy was present in 52% (116/223) vs. 14% (17/125), with sight‐threatening retinopathy in 16% (35/223) vs. 6% (7/125) of women with type 1 and type 2, respectively. Women without retinopathy in early and late pregnancy were characterized by shorter diabetes duration (p < 0.0001 and p = 0.008) and predominance of type 2 diabetes. Amongst the 50% (175/348) of the cohort having no retinopathy in early pregnancy and HbA1c<53 mmol/mol (7.0%), none developed sight‐threatening retinopathy and 94% (165/175) remained without any retinopathy during pregnancy. Development of sight‐threatening retinopathy was mainly observed in women with retinopathy in early pregnancy. Treatment for sight‐threatening retinopathy was given to a minority (2.7 and 2.4%, respectively). Conclusion: Good glycaemic control and no retinopathy was seen in a large proportion of women in early pregnancy and none of these women developed sight‐threatening retinopathy. The frequency of retinal screening can probably be safely reduced during pregnancy in these women. [ABSTRACT FROM AUTHOR]

Background: Recent development of cataract surgery has led to the improvement of visual outcomes. However, pseudophakic cystoid macular oedema (CME), which is also known as Irvine–Gass syndrome, remains a usual cause of unexpected visual disturbance after both complicated and uncomplicated cataract surgeries. Optical coherence tomography is an important method in detecting changes prior to clinical presentation. Aim: To assess macular thickness changes after uncomplicated phacoemulsification using spectral domain optical coherence tomography (SD-OCT). Setting: The study assessed healthy patients who had uneventful phacoemulsification and changes in macular thickness in Ibn Al Haitham Teaching Eye Hospital (tertiary eye center), Baghdad, Iraq. Methods: Macular thickness of 86 eyes with uncomplicated phacoemulsification were measured by using four OCT examinations: one preoperatively, which was used as a control, and three in the first week and first and second months. Incidence of macular thickness changes was evaluated in the central and para and perifoveal areas to detect which areas of the macular map will be affected more. Significance was tested by using paired t-test and p 0.05 was considered significant. Results: Significant increase in macular thickness postoperatively during the 2-month period reaching the maximum level in the second month; early significant changes were noticed in paracentral area in the first week whilst significant increase in the central and pericentral area was recorded in the first month. Cystoid macular oedema (CME) was detected in six eyes (7%) in the second month. Conclusion: Significant variation in macular thickness can occur after uneventful phacoemulsification surgery in healthy patients. Cystoid macular oedema was detected in 7% of our patients using SD-OCT. It is rare after uncomplicated phacoemulsification in healthy individuals but should be kept in mind in the follow-up period. A detailed fundus examination with OCT imaging is thus recommended in the first or second month postoperatively for the early detection and treatment of CME.

Purpose: To compare the efficacy of topical nepafenac 0.1% versus intravitreal triamcinolone acetonide (IVTA) at the conclusion of vitrectomy surgery versus no adjuvant therapy (NAT) in improving macular morphology post‐operatively in patients undergoing vitrectomy for epiretinal membrane (ERM), as measured by optical coherence tomography (OCT) imaging and best‐corrected visual acuity (BCVA). Methods: Design: Prospective randomized clinical trial Setting: Multi‐centre 80 patients scheduled to undergo vitrectomy surgery for idiopathic ERM were randomized to receive either IVTA (4 mg/0.1 cc) at the end of surgery, topical nepafenac sodium 0.1% TID for 1 month post‐operation or no adjuvant treatment (NAT). Optical coherence tomography (OCT) imaging, best‐corrected visual acuity and intraocular pressure (IOP) were measured before surgery, and 1 and 2 months post‐operation. Results: Although all three groups showed reduction in macular thickness post‐operation, the NAT group showed the most improvement, with a reduction of 136.18 ± 29.84 μm at two months. There was no statistically significant difference in macular thickness between the groups at each time point, p = 0.158. The NAT group also had the best recovery in BCVA with an improvement of 0.207 logMAR (10.35 letters) at two months post‐operation. There was no statistically significant difference in BCVA between the groups, p = 0.606. There was statistically significant difference in the IOP between the three groups, p = 0.04 only at 1‐month visit. The IVTA group had the highest rise in average IOP at both 1 and 2 months post‐operation (2.72 and 1.58 mmHg, respectively). Conclusion: Our study data suggest there was no advantage in the use of topical nepafenac or IVTA for post‐vitrectomy ERM surgery. [ABSTRACT FROM AUTHOR]

Background: This post hoc analysis compared the efficacy and safety of suprachoroidally administered triamcinolone acetonide (CLS-TA) to other commonly available treatments for non-infectious uveitis. Methods: Results from the PEACHTREE study were compared between subjects randomised to CLS-TA not requiring rescue therapy and those subjects randomised to control, who subsequently required rescue therapy. Endpoints included best corrected visual acuity (BCVA), central subfield thickness (CST), treatment emergent adverse events 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 CLSTA 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% vs. 13.0%). There were no IOP-lowering 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. [ABSTRACT FROM AUTHOR]

Background: Post fever uveoretinal sequelae (PFURS) are the various uveoretinal manifestations seen after a systemic febrile illness in an immunocompetent individual caused by bacteria, viruses, and protozoa. These may be the result of a direct invasion by the pathogen or by indirect mechanism mediated through immune mechanisms. Method: The authors aim to review the ocular manifestations, utility of relevant diagnostic tests, management, and prognosis of PFURS. A comprehensive literature search was conducted on PubMed and Google Scholar databases with the search words “retinitis”, “choroiditis”, “neuroretinitis”, “macular edema”, “maculopathy”, “multifocal retinitis”, “chikungunya”, “dengue”, “West Nile”, “typhoid”, and “rickettsiosis”. Only articles published or translated into English language were considered. The key data were extracted, evaluated, and combined. Results: The authors search yielded 95 articles for the period between 1986 and May 2020. Painless blurring of vision was the most common symptom. Patients can have varied posterior segment manifestations, including vitritis, focal and multifocal patches of retinitis which could be unilateral or bilateral, optic nerve involvement, serous detachment at the macula, macular oedema, and localised involvement of the retinal vessels in the form of beading of the vessel wall, tortuosity, and perivascular sheathing. Conclusion: PFURS presents with a similar morphological pattern irrespective of the aetiology and follows a preset natural course before resolution. Treatment may or may not be required. Treating physicians need to be aware of this important ophthalmic condition even after complete resolution of fever.

Abstract Background Whether they are injected peri- or intraocularly, corticosteroids are still essential tools in the therapeutic arsenal for treating inflammatory macular oedema. A few years ago, however, only triamcinolone acetonide was available to ophthalmologists. While this compound was initially developed for rheumatological or dermatological use, it has been increasingly deployed in ophthalmology, despite still being off-label. In 2011, the system for delivery of dexamethasone from a biodegradable, injectable implant into the vitreous cavity obtained approval for use in inflammatory macular oedema. While the efficacy and safety of triamcinolone in macular oedema, including inflammatory oedema, have already been studied, there are currently no publications on subconjunctival triamcinolone injections, which are simple, effective and well tolerated. To date, the dexamethasone 700 μg implant has been authorized for the treatment of noninfectious intermediate and posterior uveitis, but there have been no studies to evaluate the efficacy and safety of the different peri- and intraocular strategies, including the treatment of inflammatory macular oedema. Methods This protocol is therefore designed to compare the efficacy and safety of peri- and intraocular corticosteroid injections in the treatment of inflammatory macular oedema. In this ongoing study, 142 patients will be included, and the oedematous eye will be randomised to treatment with either subconjunctival triamcinolone injection or an intravitreal implant containing 700 μg dexamethasone. Follow-up is planned for 6 months with monthly visits. Each visit will include visual acuity measurement, a slit lamp examination, fundoscopy, intraocular pressure measurement, laser flare measurement (if available) and spectral domain optical coherence tomography. Discussion The results of this trial will have a real impact on public health if it is shown that a Kenacort retard® (i.e. triamcinolone) injection costing just €2.84 and performed in the physician’s office (with no additional overhead costs) is at least as effective as the dexamethasone 700 μg implant (Ozurdex®; costing approximately €960 with the injection performed in a dedicated room), with no increased side effects. Trial registration ClinicalTrials.gov, NCT02556424. Registered on 22 September 2015.

Purpose: To assess the prevalence of vitreomacular adhesion (VMA) in consecutive naïve eyes diagnosed with macular oedema (ME) secondary to retinal vein occlusion (RVO) and to longitudinally evaluate the incidence of vitreomacular interface changes over time and the influence on response to treatment. Design: Retrospective cross‐sectional analysis and longitudinal cohort study conducted at two Italian tertiary referral centres. Methods: A total of 295 eyes, treated with intravitreal ranibizumab and/or dexamethasone for ME secondary to RVO between June 2008 and May 2018, were enrolled in the study. 280 fellow eyes met the inclusion criteria and were included as control group. The vitreomacular interface status was evaluated by spectral domain optical coherence tomography (OCT) and graded according to the OCT‐based International Classification System developed by the International Vitreomacular Traction Study (IVTS) group. Results: At baseline, VMA was present in 130 (44.07%) RVO eyes and 142 (50.7%) control eyes (no statistically significant difference was found; p = 0.455). Mean follow‐up (FU) was 35.98 months (min 6 – max 112). Throughout the FU, the incidence of spontaneous release of VMA (RVMA) in RVO eyes was significantly higher in comparison with that of the control group [59 (41.84%) RVO eyes versus 18 (12.33%) control eyes; p < 0.0001]. The number of injections in VMA+ eyes was significantly higher when compared with VMA− eyes. No significant difference was found between VMA+ and VMA− eyes regarding their mean best‐corrected visual acuity (BCVA) at baseline and at each annual time point (p = 0.2). Differences in central macular thickness (CMT) were significant only at the baseline evaluation (p = 0.0303). Conclusions: Vitreomacular adhesion (VMA) was not found to be more prevalent in eyes with RVO compared to healthy fellow eyes, and RVO, in turn, did not result in a higher persistence of VMA over time. This suggests that VMA and RVO might be two independent retinal phenomena, with no mutual pathogenetic influence. Vitreomacular adhesion (VMA) might have an impact on the response to treatment, since it was found to result in a more intensive treatment regimen; however, it did not affect visual and anatomic outcomes. These results do not support vitrectomy or PVD induction in the prevention, nor the treatment, of RVO. [ABSTRACT FROM AUTHOR]

Thus, it is essential that practitioners appreciate the impending effect that increasing incidence of diabetes has on patients and the wider community. Accordingly, this study examines the humanistic burden of intravitreal injections for the treatment of diabetic macular oedema (DMO) among several health variables.Methods: Survey data from a representative sample of Australian adults undergoing treatment for DMO were examined. Respondents participated via an online survey recruited by means of a national online consumer panel and the New South Wales and Victorian Diabetes Foundations. The online survey included questions relating to the humanistic burden of disease, such as the emotional and physical impact of intravitreal injection therapy; the practical impacts of injection therapy; and to identify potential improvements to treatment regimens.Results: Sixty-five participants took part in the online survey. Of these, 49% had their most recent injection

Background: Licensed ranibizumab (0.5 mg/0.05 ml Lucentis®; Novartis International AG, Basel, Switzerland) and aflibercept (2 mg/0.05 ml Eylea®; Bayer AG, Leverkusen, Germany) and unlicensed bevacizumab (1.25 mg/0.05 ml Avastin®; F. Hoffmann-La Roche AG, Basel, Switzerland) are used to treat macula oedema due to central retinal vein occlusion, but their relative clinical effectiveness, cost-effectiveness and impact on the UK NHS and Personal Social Services have never been directly compared over the typical disease treatment period. Objective: The objective was to compare the clinical effectiveness and cost-effectiveness of three intravitreal antivascular endothelial growth factor agents for the management of macula oedema due to central retinal vein occlusion. Design: This was a three-arm, double-masked, randomised controlled non-inferiority trial. Setting: The trial was set in 44 UK NHS ophthalmology departments, between 2014 and 2018. Participants: A total of 463 patients with visual impairment due to macula oedema secondary to central retinal vein occlusion were included in the trial. Interventions: The participants were treated with repeated intravitreal injections of ranibizumab (n = 155), aflibercept (n = 154) or bevacizumab (n = 154). Main outcome measures: The primary outcome was an increase in the best corrected visual acuity letter score from baseline to 100 weeks in the trial eye. The null hypothesis that aflibercept and bevacizumab are each inferior to ranibizumab was tested with a non-inferiority margin of –5 visual acuity letters over 100 weeks. Secondary outcomes included additional visual acuity, and imaging outcomes, Visual Function Questionnaire-25, EuroQol-5 Dimensions with and without a vision bolt-on, and drug side effects. Cost-effectiveness was estimated using treatment costs and Visual Function Questionnaire-Utility Index to measure quality-adjusted life-years. Results: The adjusted mean changes at 100 weeks in the best corrected visual acuity letter scores were as follows – ranibizumab, 12.5 letters (standard deviation 21.1 letters); aflibercept, 15.1 letters (standard deviation 18.7 letters); and bevacizumab, 9.8 letters (standard deviation 21.4 letters). Aflibercept was non-inferior to ranibizumab in the intention-to-treat population (adjusted mean best corrected visual acuity difference 2.23 letters, 95% confidence interval –2.17 to 6.63 letters; p = 0.0006), but not superior. The study was unable to demonstrate that bevacizumab was non-inferior to ranibizumab in the intention-to-treat population (adjusted mean best corrected visual acuity difference –1.73 letters, 95% confidence interval –6.12 to 2.67 letters; p = 0.071). A post hoc analysis was unable to demonstrate that bevacizumab was non-inferior to aflibercept in the intention-to-treat population (adjusted mean best corrected visual acuity difference was –3.96 letters, 95% confidence interval –8.34 to 0.42 letters; p = 0.32). All per-protocol population results were the same. Fewer injections were required with aflibercept (10.0) than with ranibizumab (11.8) (difference in means –1.8, 95% confidence interval –2.9 to –0.8). A post hoc analysis showed that more bevacizumab than aflibercept injections were required (difference in means 1.6, 95% confidence interval 0.5 to 2.7). There were no new safety concerns. The model- and trial-based cost-effectiveness analyses estimated that bevacizumab was the most cost-effective treatment at a threshold of £20,000–30,000 per quality-adjusted life-year. Limitations: The comparison of aflibercept and bevacizumab was a post hoc analysis. Conclusion: The study showed aflibercept to be non-inferior to ranibizumab. However, the possibility that bevacizumab is worse than ranibizumab and aflibercept by 5 visual acuity letters cannot be ruled out. Bevacizumab is an economically attractive treatment alternative and would lead to substantial cost savings to the NHS and other health-care systems. However, uncertainty about its relative effectiveness should be discussed comprehensively with patients, their representatives and funders before treatment is considered. Future work: To obtain extensive patient feedback and discuss with all stakeholders future bevacizumab NHS use. Trial registration: Current Controlled Trials ISRCTN13623634.

Background: Anti-VEGF agents have been proven to be effective in treating macular oedema secondary to a multitude of pathological conditions. However, in large clinical trial settings, the results may be overstated. This study aimed to evaluate the short-term efficacy of intraocular Bevacizumab in consecutive patients with macular oedema being treated in a 'real-world' setting in Pakistan. Methods: A prospective study was conducted at Amanat Eye Hospital, Rawalpindi from August 2018 to November 2019. Thirty-five eyes of 29 patients with macular oedema were treated with monthly intravitreal Bevacizumab injections for three consecutive months. Best-corrected visual acuity (BCVA), and OCT parameters including central retinal thickness (CRT) and macular volume were assessed prior to the injections and then 4 weeks post the final injection and compared. Results: BCVA improved from 1.00±0.44 at baseline to 0.83±0.48 four weeks after the third intravitreal injection. CRT decreased significantly from 492.77±192.31 at baseline to 362.91±126.11 (p<0.05), and macular volume decreased significantly from 11.61±2.39 at baseline to 9.87±1.68 (p<0.05) four weeks after the third intravitreal injection. No systemic or ocular complications were observed during the course of the study. Conclusion: Treatment with intravitreal Bevacizumab injections was found safe and resulted in clinically and statistically significant improvement in SD-OCT parameters and visual acuity in patients with macular oedema secondary to various retinal pathologies. However, the improvement in a real-world setting was sub-optimal in comparison to larger clinical trials for specific diseases in the developed world. [ABSTRACT FROM AUTHOR]

The prevalence of diabetes is rapidly increasing, and it is now the leading cause of blindness worldwide. Although early detection of diabetic retinopathy is key to preventing vision loss, many patients do not receive appropriate examinations. Using a multidisciplinary approach, primary care physicians and eye care providers should follow evidence‐based recommendations for screening and monitoring diabetic patients while working to improve patients' glycaemic index, blood pressure, and metabolic risk factors. Anti‐vascular endothelial growth factor intravitreal injections in combination with panretinal photocoagulation and focal laser treatment remain the cornerstones of modern therapy. The many landmark studies for diabetic eye disease management should guide counselling and decision making for treating diabetic macular oedema, proliferative retinopathy and other diabetes‐related eye diseases.

Macular oedema is a rare complication of fingolimod treatment. It usually presents within 3–4 months, but occasionally presents later. It can resolve without treatment despite continuation of fingolimod treatment. Herein we report a case of very late onset macular oedema in a 49-year-old woman with multiple sclerosis treated with fingolimod for 7 years. The patient presented with blurred vision in both eyes with visual acuities of 20/32 in her right eye and 20/25 in her left eye. She had macular oedema, that without discontinuing fingolimod treatment, resolved after 1 month. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the efficacy of a treat-and-extend (T&E) regimen of ranibizumab as the first-choice treatment in macular oedema (MO) secondary to branch retinal vein occlusion (BRVO). We conducted a retrospective study of 20 patients who developed MO due to BRVO treated with intravitreal ranibizumab in a T&E regimen between 2016 and 2017 with a minimum follow-up of two years. Patients were classified as complete responders if treated with ranibizumab alone or incomplete responders if salvage treatment with other medications or laser was needed. Data on best corrected visual acuity (BCVA) and central macular thickness (CMT) every 6 months were recorded. The mean BCVA (logMAR) improved from 0.60 ± 0.36 to 0.29 ± 0.44 and the CMT decreased from 559.85 ± 198.61 to 305.85 ± 11.78 μm. We found statistically significant differences between complete and incomplete responders on the average number of injections during the second year (2.46 ± 2.18 compared to 5.43 ± 1.27; p = 0.007) and change of the BCVA and CMT between both groups (p < 0.001) at 6, 12, 18 and 24 months. T&E seems to be effective in MO secondary to BRVO, improving visual function and decreasing CMT, with less need for injections.

Ricardo Alexandre Stock, Daiane Karen Galvan, Rafael Godoy, Elcio Luiz Bonamigo Universidade do Oeste de Santa Catarina, Joaçaba, Santa Catarina, Brazil Purpose: To analyze, using optical coherence tomography, the macular thickness values of patient groups using nonsteroidal anti-inflammatory drug (NSAID) eye drops or artificial tears during uncomplicated cataract surgery.Methods: A total of 77 eyes from 42 patients were analyzed. The patients were divided into three groups, each using one of the following ophthalmic sterile suspensions: nepafenac (21 eyes), propylene glycol (24 eyes), or ketorolac tromethamine (32 eyes).Results: The mean macular thicknesses of the nepafenac group, preoperatively as well as at 1, 7, and 45 days postoperatively, were 216.42, 216.61, 222.47, and 218.28, respectively; those of the propylene glycol control group were 218.29, 214.50, 219.37, and 228.45, respectively; and those of the ketorolac tromethamine group were 217.46, 220.71, 225.25, and 228.46, respectively. There were no significant differences between groups at any time, with p-values of 0.971, 0.6742, 0.6711, and 0.327, respectively.Conclusion: During the study period, no significant differences in macular thickness were observed between the patient groups using two types of NSAIDs or between those groups and the control group that used propylene glycol, indicating that neither drug was superior to the other or the placebo. However, a slight macular thickening, without reduction of visual acuity, was observed in all groups.

Background: The current article is a short review of an Alimera Sciences-sponsored symposium held during The 15th International Ocular Inflammation Society Congress in Taiwan on the 14th November 2019 entitled, 'Preventing relapse of non-infectious uveitis effecting the posterior segment of the eye – evaluating the 0.2 μg/day fluocinolone acetonide intravitreal implant.' Main text: The fluocinolone acetonide intravitreal implant was approved in Europe for the prevention of relapse in recurrent non-infectious uveitis affecting the posterior segment of the eye and offers a systemic therapy-sparing treatment option by providing low daily dose of corticosteroid into the vitreous for up to 3 years. In the symposium, the presenters reported clinical outcomes from patients with non-infectious uveitis effecting the posterior segment of the eye to support the effectiveness and safety of the implant for up to 3 years in both randomised controlled trials and real-world practices. Conclusions: Data showed that over a 36 month period, treatment with the fluocinolone acetonide intravitreal implant was associated with significantly fewer episodes of uveitic recurrence, a significantly longer time to uveitic recurrence, greater improvement in visual acuity, a lower need for adjunctive therapy, and an acceptable safety profile.

Purpose: To investigate clinical baseline characteristics and optical coherence tomography biomarkers predicting visual loss during observation in eyes with diabetic macular oedema (DMO) and good baseline visual acuity (VA). Methods: A sub‐analysis of a 12‐month, retrospective study, including patients with baseline VA ≤0.1 logMAR (≥20/25 Snellen) and centre‐involving DMO. The primary outcome measure was the correlation between baseline characteristics and VA loss ≥10 letters during follow‐up. Results: A total of 249 eyes were included in the initial study, of which 147 eyes were observed and 80 eyes received anti‐vascular endothelial growth factor (VEGF) treatment at baseline. Visual acuity (VA) loss ≥10 letters occurred in 21.8% (observed cohort) and in 24.3% (treated cohort), respectively. Within observed eyes, presence of hyperreflective foci [HRF; odds ratio (OR): 3.18, p = 0.046], and disorganization of inner retina layers (DRIL; OR: 2.71, p = 0.026) were associated with a higher risk of VA loss ≥10 letters. In observed eyes with a combined presence of HRF, DRIL and ellipsoid zone (EZ) disruption, the risk of VA loss was further increased (OR: 3.86, p = 0.034). In eyes with combined presence of DRIL, HRF and EZ disruption, risk of VA loss was 46.7% (7/15 eyes) in the observed cohort, and 26.3% (5/19 eyes) in the treated cohort (p = 0.26). Conclusion: Patients with DMO and good baseline VA, managed by observation, are of increased risk for VA loss if DRIL, HRF and EZ disruption are present at baseline. Earlier treatment with anti‐VEGF in these patients may potentially decrease the risk of VA loss at 12 months. [ABSTRACT FROM AUTHOR]

Purpose: To report on the prevalence of diabetes, diabetic macula oedema (DME) and retinopathy and their respective grading in a large cohort of patients undergoing cataract surgery. Methods: Data on previous diagnosis of diabetes, fasting glucose, glycated haemoglobin, presence and type of retinopathy and other maculopathy of 3657 patients over 55 years of age undergoing cataract surgery in 13 centres scattered throughout Italy were analysed. Results: A total of 20.4% of patients were known diabetics and 27.9% of diabetics showed signs of retinopathy. Haemoglobin A1C was higher than 48 mmol/L (6.5%) in 32% of diabetics and 2.4% non-diabetics. Fasting blood glucose level was higher than 120 mg/dL in 4.3% non-diabetics and 50% diabetics. Duration of diabetes did not significantly correlate with either fasting glucose or glycated haemoglobin, while higher grades of diabetic retinopathy were significantly more prevalent as duration of disease increased. DME was present in almost 40% of diabetics and 22% of patients showed non-diabetic maculopathy. Discussion: Diabetic retinopathy and DME worsen after cataract extraction thus complicating long-term prognosis and requiring expensive injective therapy. Since unknown diabetics represent 2–4% of the many million cataract candidates and even known diabetics show poor metabolic control and high rates of DME, preoperative medical testing and accurate retinopathy screening may prove both ethically necessary and cost-effective.

Macular oedema is a known side effect to fingolimod, but changes in specific areas of the retina are only sparsely described. Our aim was to investigate the prevalence of macular oedema and characterize macular changes after initiation of fingolimod based on routine ophthalmological examinations in all consecutive patients treated at our hospital. We evaluated macular thickness change from baseline to 3‐4 months after initiation of treatment. Central retinal thickness, total macular volume, total macular thickness, average thickness and inner‐/outer macular thickness were automatically measured using optical coherence tomography (OCT). A total of 190 eyes completed the study, and none of those developed visible macular oedema. All macular areas showed a small, but statistically significant increase in thickness. Total macular volume increased by a mean of 0.05 mm3 (P = <.001). Mean best‐corrected visual acuity only changed by.03 (P =.074). We observed a minimal change in macular thickness and no clinically relevant affection on visual acuity after 3‐4 months of fingolimod treatment. Thus, our results do not underpin the need for routine screening for macular oedema in asymptomatic MS patients without diabetes or uveitis receiving 0.5 mg fingolimod daily. [ABSTRACT FROM AUTHOR]

Purpose: To investigate the efficacy and safety of intravitreal dexamethasone implant as initial and only treatment for macular oedema after pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD). Methods: This study included 14 patients, who were diagnosed with macular oedema after PPV for RRD and who were treated with intravitreal dexamethasone implant. Patients were examined at the time of macular oedema diagnosis (baseline) and 1, 6 and 12 months after treatment, using best corrected visual acuity (BCVA) measurement and optical coherence tomography (OCT). Results: The mean BCVA at baseline was 0.72 ± 0.29 logMAR and improved significantly to 0.37 ± 0.21, 0.42 ± 0.19 and 0.35 ± 0.22 logMAR at month 1, 6 and 12 after treatment with dexamethasone implant. The mean central retinal thickness (CRT) was 623 ± 142 μm at baseline and decreased significantly to 339 ± 163 μm, 428 ± 131 μm and 356 ± 147 μm at month 1, 6 and 12 after treatment. Total resolution of macular oedema was observed in 10 out of 14 patients (71.4%) at month 12. Ellipsoid zone was intact in 71.4% of patients at the end of the follow-up, while 71.4% of patients received only one implant until the end of the 12-month follow-up. No adverse events were observed. Conclusions: Intravitreal dexamethasone implant was found to be effective and safe as initial treatment for macular oedema after PPV for RRD. [ABSTRACT FROM AUTHOR]

Follow-up is planned for 6 months with monthly visits. Each visit will include visual acuity measurement, a slit lamp examination, fundoscopy, intraocular pressure measurement, laser flare measurement (if available) and spectral domain optical coherence tomography.Discussion: The results of this trial will have a real impact on public health if it is shown that a Kenacort retard® (i.e. triamcinolone) injection costing just €2.84 and performed in the physician's office (with no additional overhead costs) is at least as effective as the dexamethasone 700 μg implant (Ozurdex®; costing approximately €960 with the injection performed in a dedicated room), with no increased side effects.Trial Registration: ClinicalTrials.gov, NCT02556424.

We aimed to evaluate whether macular laser still has a role in the treatment of macular oedema (MO) caused by branch retinal vein occlusion (BRVO) and provide an overview of recent studies on commonly available treatment options. A literature search was last conducted in PubMed on 26 February 2019, limited to human randomized controlled trials published in English since 2008. Seventeen articles addressing 13 trials were included in this assessment. In trials evaluating intravitreal corticosteroid and macular laser, triamcinolone was non‐inferior to laser in regard to visual acuity (VA) and central retinal thickness (CRT) outcomes. Combination treatment of dexamethasone and laser resulted in better VA and lower CRT after 6 months. In trials evaluating vascular endothelial growth factor (VEGF) inhibitors versus macular laser treatment, or sham and rescue laser, better VA and CRT of VEGF inhibition treatment was consistently reported. Results of combination treatment versus VEGF inhibition monotherapy were inconsistent, with four of six studies reporting comparable outcomes and injection burden. Study comparison was affected by considerable differences in study design and inadequate reporting of laser protocol and rescue laser. Studies evaluating angiostatic treatment as monotherapy largely report the use of rescue laser, indicating that some patients would benefit from supplemental laser treatment even in the era of intravitreal therapy. Thus, we suggest further studies on optimal design of combination therapy prioritizing longer follow‐up time to sufficiently evaluate the delayed effect of laser. [ABSTRACT FROM AUTHOR]

Purpose: To compare the efficacy, safety and tolerability of a single perioperative subconjunctival injection of triamcinolone acetonide (TA) with steroid drops for the prevention of macular oedema and ocular inflammation after cataract surgery. Methods: This prospective non‐randomized controlled clinical trial analysed 101 eyes of 101 patients having an elective cataract surgery at Kymenlaakso Central Hospital, Kotka, Finland. Fifty eyes received conventional postoperative care with dexamethasone 1 mg/ml eye drops (DEX), and 51 eyes received a perioperative 20 mg subconjunctival injection of TA. None of the eyes received postoperative topical antibiotic prophylaxis. The main outcome measures were aqueous flare, central retinal thickness (CRT), corrected distance visual acuity (CDVA) and intraocular pressure (IOP) measured at 7, 28 and 90 days after surgery. Results: Central retinal thickness (CRT) increased in DEX but not in TA‐treated eyes at 7 days (+1.2 ± 20.1 μm and −9.2 ± 24.8 μm, p = 0.031), at 28 days (+23.8 ± 62.6 μm and −3.3 ± 27.7 μm, p = 0.008) and at 90 days (+8.5 ± 24.4 μm and −5.5 ± 33.4 μm, p = 0.026). Aqueous flare increased from baseline in both groups but remained higher in DEX eyes at 90 days (+3.3 ± 9.9 photons/ms and −0.2 ± 6.6 photons/ms, p = 0.021). Corrected distance visual acuity (CDVA) and IOP changes were similar, and ocular tolerance was good in both groups. No serious adverse events were observed. Conclusions: Perioperative subconjunctival TA was effective in preventing ocular inflammation and macular oedema after cataract surgery. Subconjunctival TA combined with intracameral cefuroxime provides a noteworthy option for dropless postoperative care in modern cataract surgery. [ABSTRACT FROM AUTHOR]
