- Abstract
Purpose: The purpose of this study was to highlight a potential alternative to additional surgery for management of retinal redetachment through the use of additional facedown positioning with silicone oil tamponade., Methods: Retrospective case series of two patients evaluated with examination, multimodal imaging, including fundus photography, optical coherence tomography, and fluorescein angiography., Results: In Case 1, a 70-year-old female patient underwent surgery for a full-thickness macular hole with associated macula-off retinal detachment, but experienced a recurrent detachment and underwent a second surgery with silicone oil placement. Another recurrent detachment was found. The case was managed conservatively with facedown positioning, resulting in resolution of subretinal fluid and improvement in vision. At follow-up, the retina remained attached with stable vision. In Case 2, a 25-year-old male patient underwent a surgical repair for proliferative vitreoretinopathy retinal detachment with a scleral buckle, cryotherapy, and external drainage. After multiple redetachment surgeries with retinectomy and oil placement, another tractional redetachment of the fovea was noted. Management was with facedown positioning, and follow-up evaluation showed resolution of the subretinal fluid and improvement in vision with stability for greater than 2 months., Conclusion: For recurrent retinal redetachments with silicone oil in place, an additional week of facedown positioning can result in anatomical success and be a viable alternative or bridge to invasive surgical interventions. This approach may have greatest utility for patients who are poor surgical candidates without new peripheral pathology.

- Abstract
Purpose: Pentosan polysulfate (PPS), a drug used for interstitial cystitis, has recently been detected to cause maculopathy in a dose-dependent manner. Outer retinal atrophy is the hallmark of this condition., Methods: History, examination, and multimodal imaging were used to guide diagnosis and management., Results: We report a case of PPS-related maculopathy in a 77-year-old lady, who presented with florid retinal atrophy at the posterior pole in both eyes, and a concurrent macular hole in the left eye. She had been diagnosed with interstitial cystitis several years before for which she was prescribed PPS (Elmiron). She had noticed a drop in vision 5 years after initiation of PPS and self-discontinued the drug after 24 years of use. A diagnosis of PPS-related maculopathy with a macular hole was made. She was counselled regarding the prognosis and was advised to avoid PPS. Surgery for macular hole was deferred in view of the severe retinal atrophy., Conclusion: Pentosan polysulfate-related maculopathy can lead to severe retinal atrophy and a subsequent degenerative macular hole. A high index of suspicion is required for early detection and cessation of drug to prevent this irreversible vision loss.

- Abstract
Topic: This systematic review and meta-analysis investigates the efficacy and safety of anti-VEGF injections compared with surgical intervention in improving visual acuity (VA) and reducing complications for patients with submacular hemorrhage (SMH) due to neovascular age-related macular degeneration (AMD)., Clinical Relevance: Determining the optimal intervention for SMH in AMD is crucial for patient care., Methods: We included studies on anti-VEGF injections or surgical interventions for SMH in AMD from 7 databases, searched up to May 2024. Data extraction and quality assessment were done by 2 independent reviewers. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Meta-analysis employed random-effects models. Primary outcomes were pooled mean logarithm of the minimum angle of resolution VA difference (initial examination minus last follow-up VA) and adverse events rates., Results: A total of 43 observational studies were included: 21 (960 eyes) on anti-VEGF and 22 (455 eyes) on surgery. Comparisons were made across separate studies due to lack of head-to-head studies. Meta-analysis included 11 anti-VEGF studies (444 eyes) and 12 surgical studies (195 eyes) for VA outcomes. The mean difference in VA was -0.16 (95% confidence interval (CI), -0.24 to -0.08) for anti-VEGF and -0.36 (95% CI, -0.68 to -0.04) for surgery, with no significant difference between groups (chi-square = 1.70, df = 1, P = 0.19). Heterogeneity was high in surgical studies (I
2 = 96.2%, τ2 = 0.23, P < 0.01) and negligible in anti-VEGF studies (I2 = 7%, τ2 = 0.003, P = 0.38). The GRADE certainty was moderate for anti-VEGF and low for surgery. Anti-VEGF had lower rates of cataract (0% vs. 4.6%), proliferative vitreoretinopathy (0.1% vs. 2.0%), and retinal detachment (0.1% vs. 10.6%), but similar rates of recurrent hemorrhage (5.4% vs. 5.3%). Complications were summarized descriptively due to zero-cell problem., Conclusion: Both anti-VEGF and surgery treat SMH in AMD with similar VA outcomes but different safety profiles. Anti-VEGF is preferred for less severe hemorrhage, whereas surgery is suited for extensive hemorrhage. Despite uncertain comparative VA outcomes, treatment should be guided by clinical judgment and patient factors., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024 American Academy of Ophthalmology.

Strand E, Meshkin RS, Hoyek S, Miller JB, and Patel NA
- Abstract
Vitreous hemorrhage involves blood leakage into or around the vitreous cavity, which presents complex management decisions. Treatment options for nondiabetic vitreous hemorrhage (NDVH) traditionally include observation or early vitrectomy. Traditional guidelines have long emphasized an initial period of cautious observation. This systematic review shows that a significant portion (∼62% to 75%) of NDVH patients present a retinal tear and/or detachment upon initial presentation. B-scan ultrasonography, the primary diagnostic tool, exhibits variable sensitivities and may miss approximately half (46.4%) of underlying tears or detachments. Only 25% of observed NDVH cases clear spontaneously, while the remaining will ultimately require vitrectomy due to nonclearance (45%) or sight-threatening complications (30%). Patients under observation experience visual deficits as hemorrhage clears slowly, challenging the efficacy of traditional guidelines favoring observation. While there is no clear guideline concerning the management of NDVH, our findings suggest that early vitrectomy for severe NDVH may be the safest and most appropriate approach, provided the patient accepts procedural risks like cataract development.

Forati R, Hoyek S, Romano F, Miller JB, and Patel NA
- Abstract
A 17-year-old boy presented with a full-thickness macular hole, with 20/20 vision with eccentric fixation in the left eye. Examination of the left eye showed a large macular hole with a base diameter measuring 1,680 μm and temporal macular and mid-peripheral retinal atrophy on ultra-high-definition optical coherence tomography (OCT) scans. Microperimetry showed eccentric fixation with good nasal sensitivity. A 12x12-mm extended-field swept-source OCT angiogram showed flow loss in the temporal macula, with slight reduction noted in the choriocapillaris. Given excellent visual acuity, good tolerance by the patient, and large atrophic hole, the decision was made for observation rather than surgery.

- Abstract
Purpose: We aim to validate the previously published TWO-ROP algorithm on an external data set., Design: Retrospective consecutive study., Subjects: Infants screened for retinopathy of prematurity (ROP) between January 2013 and August 2023 at a tertiary referral multi-site., Methods: Infants with higher birth weight (BW) and greater gestational age (GA) were included and stratified into 3 groups as follows: group 1 (BW <1500 g, GA ≥30 weeks), group 2 (BW ≥1500 g, GA <30 weeks), and group 3 (BW ≥1500 g, GA ≥30 weeks)., Main Outcome Measures: The rate of ROP, treatment-warranted ROP (TW-ROP), and number of inpatient examinations were evaluated in the 3 groups., Results: In total, 1095 (33.8%) patients met the inclusion criteria. The number of patients in groups 1, 2, and 3 was 837 (76.4%), 72 (6.6%), and 186 (17.0%), respectively. Retinopathy of prematurity was detected in 120 (11.0%) patients; the rate was 9.8% in group 1, 20.8% in group 2, and 12.4% in group 3 (P = 0.013). The overall mean number of inpatient examinations for patients undergoing traditional, TWO-ROP 36-week, and TWO-ROP 40-week screening systems was 1.95, 1.43, and 0.99, respectively (P < 0.001). Stage 3 was found in 9 eyes of 5 patients (0.5%, all zone II). Three eyes of 2 patients (0.2%) had plus disease. Two patients had bilateral laser treatment at 44 and 39.4 weeks postconceptional age (PCA); 3 out of 4 of these eyes met type 1 treatment criteria. Overall, the ROP screening burden saved was 9.0% and 16.7% for the TWO-ROP 36-week and 40-week systems, respectively. The sensitivity for TW-ROP was 100% for TWO-ROP 36-week system and 99.4% for TWO-ROP 40-week system., Conclusion: The TWO-ROP algorithm can reduce the number of inpatient examinations while maintaining safety. To ensure timely management, we recommend that the single first ROP examination occur at 38 to 39 weeks PCA., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024.

- Abstract
Purpose: To identify clinical characteristics of injured eyes associated with visual recovery in patients with open globe injuries (OGIs) and presenting with no light perception (NLP) vision., Design: Retrospective chart review., Subjects: All patients presenting to Massachusetts Eye and Ear with OGI and NLP vision from January 1999 to March 2022., Methods: Manual data extraction to collect patient demographic characteristics, preoperative, intraoperative, and postoperative characteristics of OGI injury, laceration versus rupture, history of intraocular surgery, time from injury to repair, timing of vitrectomy, lensectomy, choroidal drainage, and silicone oil placement, visual acuity (VA) at last follow-up, and subsequent B-scan ultrasound findings of retinal detachment, choroidal hemorrhage, vitreous hemorrhage, and disorganized intraocular contents. Patients with >1 week of follow-up and a documented VA at most recent follow-up were included. Exclusion criteria included age <10 years. Multivariable regression was performed., Main Outcome Measures: Visual acuity recovery defined as light perception or better in patients with OGI and initial NLP vision., Results: One hundred forty-seven eyes with NLP vision after OGI were included. Twenty-five (17%) eyes regained vision at last follow-up. The majority of patients recovered light perception vision (n = 15, 60%) followed by 20/500 or better (n = 5, 20%), hand motions (n = 3, 12%), and counting fingers (n = 2, 8%). Most injuries were zone III (n = 102, 69%) and presented with rupture (n = 127, 86%). The mean time from OGI to surgical repair was 0.85 ± 1.7 days. B-scan was obtained in 104 (71%) cases. Pars plana vitrectomy was performed in 9 eyes (6%) with NLP at time of vitrectomy. Disorganized intraocular contents on B-scan (odd ratio, 0.170; 95% confidence interval, 0.042-0.681; P = 0.012) was the only clinical variable significantly associated with visual recovery, corresponding to a lack of visual improvement., Conclusions: Recovery of vision in OGI with NLP vision at presentation cannot be predicted based on presenting clinical features. B-scan findings of disorganized intraocular contents after initial OGI repair was the only factor negatively associated with vision recovery in this patient population. Therefore, all eyes presenting with an OGI and NLP vision should undergo primary repair in hopes of subsequent visual recovery., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024 American Academy of Ophthalmology.

- Abstract
We report a 23-year-old female patient with ophthalmic features of albinism, including refractive errors, nystagmus, depigmented fundus, and foveal hypoplasia. She presented for a rhegmatogenous retinal detachment, which was surgically reattached with no complications. Further genetic testing revealed the presence of a heterozygous pathogenic oculocutaneous albinism OCA2 gene mutation, conferring carrier status. To the best of our knowledge, this is the first reported case of typical ocular phenotype of albinism, specifically nystagmus, in a patient who is carrier for oculo-cutaneous albinism. Further research is required to expand the genotype-phenotype relationship in carriers of oculocutaneous albinism. [ Ophthalmic Surg Lasers Imaging Retina 2024;55:349-353.] .

- Abstract
Purpose: To describe fluorescein angiography (FA) parameters observed in premature neonates with retinopathy of prematurity (ROP)., Design: Retrospective case series., Subjects: Patients with ROP who underwent FA imaging using Retcam at Holtz Children's Hospital from November 2014 to October 2022., Methods: Fluorescein angiography images of the included patients were analyzed with a focus on the timing of angiography phases, including choroidal flush, retinal, and recirculation phases. Gestational age, birth weight (BW), age at imaging, treatment choice, and any FA complications were documented., Main Outcome Measures: Dose of fluorescein administered, onset and duration of each angiography phase, and FA findings in ROP-treated patients., Results: A total of 72 images of 72 eyes were reviewed. Image quality was deemed suitable for inclusion in 64 eyes (88.9%) of 43 patients. The mean gestational age and BW at birth were 24.4 ± 1.9 weeks and 607.8 ± 141.3 g, respectively. The mean postmenstrual age at FA imaging was 50.5 ± 40.8 weeks. All eyes (100%) received treatment with intravitreal injection of anti-VEGF at a mean age of 35.5 ± 2.4 weeks. The onset and duration of angiography phases were relatively variable within the cohort. Choroidal flush occurred at a mean time of 12.2 seconds (range: 6-22 seconds). A subsequent retinal phase was documented at a mean time of 11.96 seconds (range: 3-22 seconds). Recirculation phase was complete at an average time of 2.15 minutes (range: 1-5.45 minutes) postfluorescein injection. None of patients developed allergic reactions to fluorescein injection, such as rash, respiratory distress, tachycardia, fever, or local injection site reactions., Conclusions: Angiographic phases on FA in preterm infants with ROP are variable and may occur earlier than the established references for adults., Financial Disclosures: Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (© 2024 Published by Elsevier Inc. on behalf of the American Academy of Ophthalmology.)

Martinez-Velazquez L, Begaj T, Garg I, Zhou P, Hoyek S, Wai KM, Miller JB, and Patel NA
- Abstract
Purpose: Pre-eclampsia, eclampsia, and hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome have been previously implicated with ophthalmic complications including serous retinal detachments and disorders of the choroidal vasculature. Herein, we report a case of macular serous detachment associated with HELLP syndrome in which wide field swept-source optical coherence tomography angiography (WF SS-OCTA) was used., Methods: Retrospective case report of a patient who developed HELLP syndrome. The patient underwent multimodal retinal imaging and wide field swept-source OCT angiography (WF SS-OCTA) (PLEX® Elite 9000, Carl Zeiss Meditec Inc.)., Results: A 36-year-old female patient diagnosed with HELLP syndrome presented with bilateral blurry vision. At presentation, dilated fundus exam revealed localized subretinal fluid in the macula. WF SS-OCTA showed areas of peripapillary and subfoveal flow signal attenuation in the choroid OD, consistent with choroidal infarction., Conclusions: These findings support the hypothesis that HELLP syndrome is associated with vascular changes that lead to choroidal dysfunction and subsequent serous retinal detachments. Furthermore, this case highlights a role for the non-invasive WF SS-OCTA technology in diagnosing and further characterizing the pathophysiology without the use of dye-based angiography.

- Abstract
Purpose: The purpose of this study was to evaluate the cost effectiveness of the treatment of geographic atrophy (GA) with intravitreal avacincaptad pegol (ACP) and to compare it with pegcetacoplan (PEG)., Design: Cost analysis based on data from published studies., Subjects: None; based on data from published sham control compared with 2 treatment groups in each of the index studies., Methods: Costs were based on 2022 Medicare reimbursement data for both facility (hospital-based) and nonfacility settings in Miami. Specific usage and outcomes were derived from the GATHER2 study as well as DERBY and OAKS trials. For ACP, all patients were treated every month (EM) in year 1 then randomized to every other month (EOM) or EM in year 2. Two-year models were created for patients in the facility setting for extrafoveal (ACP and PEG) and all patients (PEG)., Main Outcome Measures: Cost, cost utility, and cost per area of GA (in United States dollars)., Results: The cost to treat GA with ACP in EM and EOM treatment groups over the 2 years as reported was $67 400 and $40 600, respectively. With ACP treatment over 2 years, the daily cost of delaying GA 3.4 months (EM) and 4.5 months (EOM) was $649 (EM) and $356 (EOM). The (facility-based) costs per unit area of retinal pigment epithelium saved for patients with extrafoveal GA over the 2-year period were $119 000/mm
2 (EM ACP) versus $54 000/mm2 (EM PEG) (P < 0.001), $57 100/mm2 (EOM ACP) versus $31 400/mm2 (EOM PEG) (P < 0.001), and $45 300/mm2 (hypothetical EOM from outset ACP)., Conclusion: Treatment of GA with intravitreal ACP EOM was more cost effective than EM. When assessing extrafoveal lesions, ACP was less cost effective than PEG for both EM and EOM treatment., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024 American Academy of Ophthalmology.

- Abstract
Background and Objective: We describe an in-office lens repositioning technique for anterior crystalline lens dislocation., Patients and Methods: We present a case series of four patients with spontaneous or traumatic anterior crystalline lens dislocation., Results: The technique included supine patient positioning, gentle pressure with a cotton swab on the peripheral cornea to guide the lens into the posterior chamber, and the use of a miotic agent afterward to prevent subsequent subluxation. In the four cases described, the in-office technique successfully restored the lens to the posterior chamber, improved vision, and decreased intraocular pressure in most instances by resolving the angle closure secondary to pupillary block., Conclusions: The in-office lens repositioning technique is appropriate as an acute non-surgical intervention or temporizing measure for anterior crystalline lens dislocation.

- Abstract
Purpose: To compare operative time and case characteristics of primary rhegmatogenous retinal detachment (RRD) repairs between academic and community vitreoretinal surgeons., Design: A retrospective, observational clinical study., Subjects: Patients who underwent primary RRD repair surgeries at Massachusetts Eye and Ear between 2019 and 2021., Methods: A random sample of 20 vitreoretinal surgeons distributed evenly among the academic or community setting was selected. Fifteen consecutive cases of primary RRD repair surgeries were included from each surgeon. A cost analysis was performed for the teaching modifier for the physician fee and for hospital costs., Main Outcome Measures: Length of surgery., Results: Of 300 primary RRD repairs, fellows were present in 75%, which comprised all academic surgeon cases and 50% of community surgeon cases, P < 0.001. Mean operation length was shorter for community surgeon cases without fellows (55.0 ± 24.1) than either academic (73.0 ± 30.8) or community surgeon cases with fellows (75.7 ± 32.5) (P < 0.001). There was a higher percentage of macula-off RRDs in academic versus community surgeon cases (52.7% vs. 38.0%, P = 0.002) and higher rates of combined scleral buckle (SB)/pars plana vitrectomy (PPV) repairs (14% vs. 3%, P < 0.001). When excluding combined SB/PPV cases, there was no difference in operative time between academic and community surgeon cases. Among RRDs repaired by PPV only, there was a 31.4% (16.6 minutes) greater procedure duration in cases with fellows compared with cases without fellows (P < 0.001). Covariates associated with greater surgery time: addition of an SB (β = 32.6), membrane peel (β = 18.5), presence of a fellow (β = 14.5), proliferative vitreoretinopathy (β = 12.8), and greater number of retinal breaks (β = 2.4). The teaching modifier adds 16% extra reimbursement ($184.16) to the physician fee, which is 50.9% of what is necessary to cover the percentage increase in surgeon time (31.4%). Using a time-driven activity-based costing for hospital costs, the extra 16.6 minutes leads to an additional $1038.00, which is 5.6 times more than the reimbursement for the modifier., Conclusions: Retinal detachment repair cases performed by academic surgeons are more likely to be macula-off and include the addition of an SB, which drive longer operative times. Medicare's reimbursement of the assistant modifier in a teaching facility significantly undercompensates the time-driven activity-based costing of trainee participation., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024 American Academy of Ophthalmology.

- Abstract
A 37-week-old girl underwent ophthalmic examination. Born at 32 weeks, the infant weighed 680 grams and received high-flow nasal cannula for respiratory distress of the newborn. Dilated fundus examination of the right eye revealed an atypical chorioretinal coloboma; the left eye revealed hyperpigmentary changes in the macula. Fluorescein angiography of both eyes showed retinal vascularization to zone II. Genetic testing revealed a heterozygous variant of uncertain significance in the catenin Alpha 1 (CTNNA1) gene. CTNNA1 gene abnormalities have been implicated as causes of familial exudative vitreoretinopathy (FEVR). It is important to recognize possible simultaneous retinopathy of prematurity and FEVR.

- Abstract
Purpose: Kearns-Sayre syndrome (KSS) is a mitochondrial DNA deletion syndrome that is characterized by the triad of onset commonly before age 20, pigmentary retinopathy, and chronic progressive external ophthalmoplegia. Here, we present a case of KSS masquerading as myasthenia gravis., Methods: Case report., Results: A 15-year-old boy with a presumed diagnosis of myasthenia gravis presented with blurry vision, ophthalmoplegia, and ptosis. He was found to have a mitochondrial pigmentary retinopathy and was eventually diagnosed with KSS after mitochondrial DNA sequencing revealed a novel large-scale deletion of 7.9 kb of mitochondrial DNA from nucleotides 6,578 to 14,460., Conclusion: We report a case of KSS found to have a novel large-scale mitochondrial DNA deletion. The presence of a mitochondrial pigmentary retinopathy found on dilated examination led to reconsideration of the previous diagnosis of myasthenia gravis and ultimately led to the correct diagnosis of KSS.

- Abstract
Purpose: To report the clinical and imaging characteristics, including optical coherence tomography angiography (OCTA), and treatment outcomes of choroidal neovascular membranes (CNVMs) in children., Design: Retrospective clinical cohort study., Methods: Thirty eyes from 25 children (56% girls) with CNVM from 2 centers were examined from 2005 to 2022. Clinical features, imaging findings, treatment regimens, and outcomes are described., Results: The most common causes of CNVM were idiopathic (48%) and inflammatory (20%). At diagnosis, most CNVMs were unilateral (80%), active (83.3%), and juxtafoveal (46.7%). Twenty-five eyes (83.3%) of 21 patients (84%) were treated. The most common first-line treatment was intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) (92%), with a retreatment rate of 52.2% at an average of 237 days. The average number of total injections per eye was 2.3. Injections were safely administered in the clinic (52.2%). A gain of 3 lines or 15 ETDRS (Early Treatment Diabetic Retinopathy Study) letters was observed at final visit. The average duration of follow-up was 56.46 ± 42.51 months. No ocular or systemic complication related to treatment was reported. Sixteen eyes (64%) had OCTA images at both presentation and final visit, which showed a decrease in CNVM vessel density and vessel-length density, and in the height of retinal pigment epithelium detachment (RPED)., Conclusions: There are a variety of underlying etiologies for pediatric CNVMs, which are most often unilateral. Treatment with intravitreal anti-VEGF can be beneficial and does not often require frequent or chronic dosing. OCTA demonstrated a decrease in the CNVM vessel density and vessel-length density as well as in the height of RPED., (Copyright © 2024 Elsevier Inc. All rights reserved.)

- Abstract
A 13-year-old Black male patient with a history of Kikuchi-Fujimoto disease (KFD) and sickle cell trait presented with acute painless vision loss and no light perception vision (NLP) in his left eye. The examination was indicative of occlusive retinal vasculitis with near total central retinal artery occlusion (CRAO). He was started on oral steroids with dramatic reperfusion and improvement of the retinal hemorrhages. However, his vision remained at NLP. Oral steroids were tapered, and rituximab infusion was initiated. While ocular involvement is uncommon in KFD, vision-limiting complications, such as occlusive retinal vasculitis, ophthalmic artery occlusion, and CRAO can occur. Early systemic immunosuppression is key in achieving rapid remission. [ Ophthalmic Surg Lasers Imaging Retina 2024;55:235-239.] .

- Abstract
Purpose: Multifocal choroiditis (MFC) is a rare inflammatory condition characterized by retinal and choroidal lesions that may present similarly to ocular pathology of various etiologies. Here we present a case of MFC mimicking syphilitic uveitis with unique en face optical coherence tomography angiography (OCTA) imaging characteristics., Methods: Case report., Results: A 61-year-old woman presented with blurry vision, floaters and multiple whitish subretinal deposits on en face swept-source OCTA in the left eye. Fluorescent treponemal antibody test absorption was positive which led to the initial diagnosis of syphilitic uveitis and subsequent treatment with intravenous penicillin. During follow-up, OCTA of the left eye revealed the development of new choroidal neovascular membrane and new punched-out lesions in the posterior pole. The patient was eventually diagnosed with MFC and treated with aflibercept injections., Conclusions: Immune-mediated uveitis can simulate infectious and neoplastic uveitis. En face OCTA is unique imaging modality that allowed for the complete characterization and monitoring of the sub-macular deposits. This expands the clinical spectrum of multifocal choroiditis.

- Abstract
Participants: This article includes 7293 infants (14 586 eyes) screened for ROP across 5 centers in the United States (Austin Retina Associates, Austin, TX; Bascom Palmer Eye Institute, Miami, FL; Beaumont Eye Institute, Royal Oak, MI; Massachusetts Eye and Ear, Boston, MA; and Stanford Byers Eye Institute, Stanford, CA)., Purpose: To analyze the incidence and timing of treatment requiring retinopathy of prematurity (ROP) in extremely small premature infants. We hypothesize that the smaller the infant by gestational age and birthweight, the higher their likelihood of requiring treatment for ROP., Design: Premature infants screened for Retinopathy of Prematurity from 2002-2022 were divided into cohorts based on the following criteria based on gestational age (GA) and birth weight (BW). "Micropremature infants" are infants born between 24-26 weeks GA and between 600-799 g BW. "Nanopremature infants" are born ≤ 24 weeks GA and ≤ 600 g BW., Methods: Retrospective chart review., Main Outcome Measures: The incidence and timing of treatment-requiring ROP., Results: We found that infants defined as nanopremature had a ∼63% chance of requiring treatment at an average postmenstrual age (PMA) of 36.6 weeks, whereas those defined as micropremature had a 30% chance of requiring treatment at an average PMA of 36.3 weeks. This significantly contrasts with the risk of all screened babies for ROP where the risk of requiring treatment was 8.5%., Conclusion: Micropremature and nanopremature infants are significantly more likely to require treatment for ROP. With demographic data matched to all 5 major US regions spanning the last decade, these results have the potential to inform neonatologists, pediatricians, and ophthalmologists of an important shift in the landscape of prematurity in the United States., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2023 American Academy of Ophthalmology.

- Abstract
Purpose: To longitudinally assess macular thickness and microvascular changes in children with sickle cell disease (SCD)., Design: A retrospective consecutive series., Subjects: Children with SCD aged ≤ 18 years who had an ophthalmic examination at Boston Children's Hospital between January 1998 and August 2022., Methods: Qualitative and quantitative analyses of both OCT and OCT angiography (OCTA) images were performed., Main Outcome Measures: Total retinal thickness measured on macular OCT, superficial capillary plexus and deep capillary plexus (DCP) vessel density (VD), and foveal avascular zone (FAZ) area measured on 6- × 6-mm OCTA scans., Results: International Classification of Diseases, 10th Revision, code search identified 303 pediatric SCD patients who underwent ophthalmic examination during the study period. OCT and OCTA images were acquired on 104 (17.2%) and 60 (9.9%) eyes at presentation and on 159 (26.2%) and 100 (16.5%) eyes at final visit, respectively. Overall, temporal retinal thinning was noted qualitatively in 35.6% of SCD patients at presentation and 39.6% at final visit. Of those patients with macular thinning, 94.6% and 90.5% had peripheral sickle cell retinopathy (SCR) at presentation and final visit. On quantitative OCT analysis, HbSS eyes had a lower retinal thickness in the fovea and temporal parafovea compared with HbSC (P < 0.05). Eyes with peripheral SCR had a larger FAZ at presentation compared with eyes without peripheral SCR (P = 0.004), a lower DCP VD at final visit in the inferior temporal macula (P = 0.03), and a higher DCP VD at final visit in the superior nasal macula (P = 0.01). Eighty eyes of 40 patients had OCT, and 34 eyes of 20 patients had both OCT and OCTA images acquired at both initial and final visits. At final visit, retinal thickness decreased at the fovea, inferior perifovea, and temporal perifovea compared with presentation (P < 0.05). In parallel, VD DCP in the superonasal quadrant increased at final visit (P = 0.03)., Conclusions: Macular retinal thinning was progressive and observed in eyes with and without peripheral SCR. Over time, there was a compensatory increase in DCP VD in the nasal macula on OCTA., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2023 American Academy of Ophthalmology.

- Abstract
Purpose: To describe novel clinical and angiographic findings in Wagner syndrome., Methods: A retrospective case series of three related patients with Wagner syndrome. Patients underwent standard optical coherence tomography (OCT), B-scan ultrasonography, and fluorescein angiography in addition to wide field swept-source OCT angiography (WF SS-OCTA) (PLEX Elite 9000, Carl Zeiss Meditec Inc). Patients underwent genetic testing for a panel of hereditary vitreoretinopathies., Results: Three related patients with Wagner syndrome were identified. All were found to have prominent vitreous strands, abnormal vitreoretinal adhesions, peripheral retinal holes, and varying degrees of myopia. A mid-peripheral tractional ridge was identified in all six eyes. All patients were positive for a known pathologic intron variant in the VCAN gene (4004-5T-A). Wide field swept-source OCT angiography (12 mm × 12 mm) was performed in two patients and demonstrated perivascular capillary loss in the superficial capillary plexus along the arcades bilaterally. One patient demonstrated associated retinal atrophy within the area of capillary loss. The capillary loss extended beyond the margin of retinal atrophy., Conclusion: The unusual finding of a mid-peripheral tractional ridge of the retina associated with myopia led to a genetic diagnosis of Wagner syndrome. Widefield swept-source OCT angiography demonstrated a novel feature of perivascular loss of the superficial retinal capillary plexus. This result suggests that vitreous traction may cause localized microvasculature dysfunction and subsequent retinal atrophy in Wagner syndrome. This is the first known evaluation of Wagner syndrome using OCT angiography.

- Abstract
Background: Aicardi syndrome is a neurodevelopmental disorder characterized by a triad of partial or complete agenesis of the corpus callosum, infantile spasms, and pathognomonic chorioretinal lacunae., Methods: Examination, multimodal imaging, and genetic testing were used to guide diagnosis., Results: We report a case of a pediatric patient who was initially diagnosed with refractory infantile spasms. The patient was unresponsive to conventional antiepileptic therapy, and genetic testing with whole exome and mitochondrial genome sequencing could not identify the underlying cause, so vigabatrin was initiated. The ophthalmic examination under anesthesia for vigabatrin toxicity screening revealed chorioretinal atrophy in the retinal periphery of both eyes, with two 3-disc diameter chorioretinal lacunae superotemporal and inferonasal to the optic nerve in the left eye. Given the neuroimaging findings of corpus callosum hypoplasia with polymicrogyria and ocular findings, the patient was diagnosed with Aicardi syndrome. Genetic testing revealed a novel duplication event at the Xp22 locus., Conclusions: Aicardi syndrome, albeit a rare condition, should always be considered in the differential diagnosis when investigating a female child with refractory seizures in early childhood. Genetic testing may help further our understanding of AIS and the search for a genetic etiology.

- Abstract
Retinopathy of prematurity (ROP) is a leading cause of preventable vision loss in preterm infants. While appropriate screening is crucial for early identification and treatment of ROP, current screening guidelines remain limited by inter-examiner variability in screening modalities, absence of local protocol for ROP screening in some settings, a paucity of resources and an increased survival of younger and smaller infants. This review summarizes the advancements and challenges of current innovative technologies, artificial intelligence (AI), and predictive biomarkers for the diagnosis and management of ROP. We provide a contemporary overview of AI-based models for detection of ROP, its severity, progression, and response to treatment. To address the transition from experimental settings to real-world clinical practice, challenges to the clinical implementation of AI for ROP are reviewed and potential solutions are proposed. The use of optical coherence tomography (OCT) and OCT angiography (OCTA) technology is also explored, providing evaluation of subclinical ROP characteristics that are often imperceptible on fundus examination. Furthermore, we explore several potential biomarkers to reduce the need for invasive procedures, to enhance diagnostic accuracy and treatment efficacy. Finally, we emphasize the need of a symbiotic integration of biologic and imaging biomarkers and AI in ROP screening, where the robustness of biomarkers in early disease detection is complemented by the predictive precision of AI algorithms., (Copyright © 2023 Elsevier Ltd.

- Abstract
We report the case of a 28-year-old man with X-linked retinoschisis (XLRS) and type I diabetes mellitus. The patient had bilateral foveoschisis with a tractional retinal fold in the right eye. Optical coherence tomography (OCT) revealed hyperreflective material within the inner nuclear and outer plexiform layers, photoreceptor atrophy, and retinal pigment epithelium irregularities in both eyes. Fluorescein angiography showed hyperfluorescent foveal spots corresponding to the hyperreflective material observed on OCT. This is a unique presentation of XLRS, with concurrent foveoschisis and photoreceptor atrophy in both eyes. The hyperreflective material on OCT serves as a distinctive feature of XLRS.

- Abstract
Background and Objective: Inducing a posterior vitreous detachment (PVD) may be challenging, especially in pediatric patients with firm vitreo-retinal adherence. This case report will present an alternative method of PVD induction using adjunctive perfluorooctane (PFO)., Materials and Methods: An 11-year-old boy underwent scleral buckle placement and 23-gauge pars plana vitrectomy for macula-off retinal detachment. Triamcinolone acetonide was used for vitreous staining. A flexible loop was used to peel the hyaloid membrane from attached retina nasal to the optic nerve. A small hole was created in the posterior hyaloid, and a small PFO bubble was injected under the detached vitreous to further dissect it from the retina and propagate the vitreous detachment anteriorly. The vitrector was used to lift and complete the PVD peripherally., Results: PVD induction was obtained with no iatrogenic retinal breaks or postoperative complications., Conclusion: PVD induction using a stepwise PFO approach is a safe and effective alternative to conventional techniques.

- Abstract
Purpose: To assess the rates of retinopathy of prematurity (ROP) and treatment-warranted ROP in a modern set of patients meeting 0 or 1 of the current ROP screening criteria., Design: Retrospective cohort study., Methods: Single-center study of 9350 infants screened for ROP from 2009 to 2019. Rates of ROP and treatment-warranted ROP were evaluated in group 1 (birth weight [BW] <1500 g and gestational age [GA] ≥30 weeks), group 2 (BW ≥1500 g and GA <30 weeks), and group 3 (BW ≥1500 g and GA ≥30 weeks)., Results: Of 7520 patients with reported BW and GA, 1612 (21.4%) patients met the inclusion criteria. The number of patients in groups 1, 2, and 3 was 466 (6.19%), 23 (0.31%), and 1123 (14.93%), respectively. The number of patients diagnosed with ROP was 20 (4.29%) in group 1, 1 (4.35%) in group 2, and 12 (1.07%) in group 3 (P < .001). The mean interval between birth and ROP diagnosis was 36.25 days (range 12-75 days) in group 1, 47 days in group 2, and 23.33 days (range 10-39 days) in group 3 (P = .05). No cases of stage 3, zone 1, or plus disease were recorded. No patients met the treatment criteria., Conclusions: Patients meeting 1 screening criterion had a low rate of ROP (<5%), with no stage 3, zone 1, or plus disease. No patients required treatment. We propose a possible algorithm (TWO-ROP) in appropriate neonatal intensive care units, with an amendment in screening protocol for this low-risk population to include only an outpatient screening examination within 1 week of discharge, or at 40 weeks if inpatient, to decrease the inpatient ROP screening burden while maintaining safety. Further external validation of this protocol would be required., (Copyright © 2023 Elsevier Inc. All rights reserved.)

- Abstract
Non-fungible tokens (NFTs) are cryptographic assets recorded on the blockchain that can certify authenticity and ownership, and they can be used to monetize health data, optimize the process of receiving a hematopoietic stem cell transplant, and improve the distribution of solid organs for transplantation. Blockchain technology, including NFTs, provides equitable access to wealth, increases transparency, eliminates personal or institutional biases of intermediaries, reduces inefficiencies, and ensures accountability. Blockchain architecture is ideal for ensuring security and privacy while granting individuals jurisdiction over their own information, making it a unique solution to the current limitations of existing health information systems. NFTs can be used to give patients the option to monetize their health data and provide valuable data to researchers. Wearable technology companies can also give their customers the option to monetize their data while providing data necessary to improve their products. Additionally, the process of receiving a hematopoietic stem cell transplant and the distribution of solid organs for transplantation could benefit from the integration of NFTs into the allocation process. However, there are limitations to the technology, including high energy consumption and the need for regulatory guidance. Further research is necessary to fully understand the potential of NFTs in healthcare and how it can be integrated with existing health information technology. Overall, NFTs have the potential to revolutionize the healthcare sector, providing benefits such as improved access to health information and increased efficiency in the distribution of organs for transplantation., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Yaghy et al.

- Abstract
Purpose: Postoperative endophthalmitis is a relatively uncommon, but potentially visually devastating, complication associated with cataract surgery. Specific microbial causes of endophthalmitis are characteristically associated with particular disease time courses. Though Cutibacterium acnes is typically associated with an indolent course of inflammation, we report a case of C. acnes endophthalmitis with onset on postoperative day (POD) 1 and a positive culture from POD 2., Methods: Case report., Results: A 56-year-old man underwent cataract extraction and posterior chamber intraocular lens placement in his left eye. On POD 1, he presented with severe discomfort, reduced visual acuity, and significant inflammation. On POD 2, his anterior chamber was tapped and injected with broad-spectrum antibiotics and steroids. The inflammation ultimately resolved, and his visual acuity improved to 20/20., Conclusions: C. acnes is a rare cause of hyperacute onset postoperative endophthalmitis. Maintaining a high clinical suspicion and initiating prompt treatment can help to optimize long-term visual outcomes., Competing Interests: The following authors report no conflict of interest: BMH, SH, and SHG

- Abstract
Purpose: To report 2 cases of persistent inflammation associated with human leukocyte antigen-B27 (HLA-B27) after pars plana vitrectomy (PPV) with scleral buckling. Methods: Two cases were analyzed. Results: A 47-year-old man had pars plana vitrectomy (PPV), scleral buckle (SB) placement, and endolaser for a macula-on rhegmatogenous retinal detachment (RRD). A 61-year-old man also had uneventful PPV, SB placement, and endolaser for a macula-off RRD. Postoperatively, both patients reported eye pain and had persistent intraocular inflammation. Both were found to be HLA-B27 positive despite having no previous signs or symptoms that would warrant HLA-B27 testing. Conclusions: Discovering the source of prolonged postoperative inflammation is critical in initiating the correct treatment and removing suspicion of infection. Although intraocular inflammation associated with HLA-B27 does not often present initially after surgery, HLA-B27 testing should be considered in cases of persistent, unexpected postoperative inflammation., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Dr. Patel is a consultant to Atheneum, Alcon, Allergan, Alimera, Eyepoint, Lifesciences, Genentech, Guidepoint, and Regeneron.

Fairbanks AM, Hoyek S, and Patel NA
- Abstract
Purpose: To describe cases of asymptomatic peripheral retinal hemorrhage attributed to presumed vitreous base traction seen on ultra-widefield (UWF) imaging. Methods: This retrospective consecutive series comprised asymptomatic patients with peripheral retinal hemorrhages, microaneurysms, or both. Imaging included UWF fundus photography, fundus autofluorescence, fluorescein angiography (FA), optical coherence tomography (OCT), or a combination. Results: The series included 9 adult patients. The findings were observed on a routine eye examination or as an incidental finding in the contralateral eye of patients presenting with a retinal break or detachment. On UWF imaging, the distinguishing features of the peripheral retinal hemorrhages and microaneurysms presumably caused by vitreous base traction were their pinpoint shape and location at the vitreous base, in particular in the far temporal and superior retinal periphery. UWF FA showed punctate hyperfluorescent spots with no leakage. OCT showed signs of evolving posterior vitreous detachment. Management was limited to observation; with time, the microaneurysms were stable and the hemorrhages resolved. Conclusions: UWF imaging has led to the identification of presumed vitreous base vasculopathy. After a targeted workup is unrevealing, observation is appropriate., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

- Abstract
Purpose: To describe the clinical features and visual outcomes of eyes with conjunctival haptic erosion after sutureless intrascleral (SIS) fixated intraocular lens (IOL) placement., Design: Retrospective case series., Subjects: Patients experiencing haptic erosion after SIS fixation between January 1, 2013, and March 1, 2022., Methods: A multicenter, multisurgeon, retrospective review., Main Outcome Measures: Clinical features, visual outcomes, and treatment options following haptic erosions after SIS fixation., Results: Nineteen eyes with haptic erosion were identified. The mean age at initial SIS fixation was 64 ± 12 years (range, 38-81 years). There were 5 (26%) eyes with a history of conjunctiva involving ocular surgery, including scleral buckle surgery and tube shunt surgery. Trocar-assisted fixation was performed in 15 (79%) eyes, whereas needle fixation was used in 4 (21%) eyes. Eighteen (95%) sets of haptics were flanged with a low temperature cautery. Seventeen (90%) sets of haptics were externalized superiorly and inferiorly, and 2 (10%) sets of haptics were externalized nasally and temporally. Haptics were covered by conjunctiva in 14 (74%) eyes and by scleral flap in 5 (26%) eyes. All patients experienced a single haptic erosion, of which 8 (43%) were located superiorly, 9 (47%) inferiorly, and 2 (10%) temporally. The mean interval between the initial SIS fixation and haptic erosion was 278 ± 437 days. After correction of the erosion, 18 (95%) eyes had a stable IOL at the last follow-up, with no recurrence of haptic erosion. In this series, there were no cases of endophthalmitis., Conclusions: Haptic erosion is a notable complication after SIS fixated IOL surgery but may be repaired with favorable visual outcomes. Careful evaluation of the conjunctiva should be considered before the surgery., Financial Disclosure(s): Proprietary or commercial disclosure may be found after the references., (Copyright © 2022 American Academy of Ophthalmology.

- Abstract
Purpose: To compare the types and dosages of anti-vascular endothelial growth factors (VEGFs) to ascertain whether specific dosages or types of injection were associated with retreatment in clinical practice in the United States., Design: Multicenter, retrospective, consecutive series., Participants: Patients with retinopathy of prematurity (ROP) treated with anti-VEGF injections from 2007 to 2021., Methods: Sixteen sites from the United States participated. Data collected included demographics, birth characteristics, examination findings, type and dose of anti-VEGF treatment, retreatment rates, and time to retreatment. Comparisons of retreatment rates between bevacizumab and ranibizumab intravitreal injections were made., Main Outcome Measures: Relative rate of retreatment between varying types of anti-VEGF therapy, including bevacizumab and ranibizumab, and the various dosages used for each., Results: Data from 873 eyes of 661 patients (61% male and 39% female) were collected. After exclusion of 40 eyes treated with laser before anti-VEGF injection and 266 eyes re-treated with laser at or beyond 8 weeks after the initial anti-VEGF treatment, 567 eyes of 307 patients (63% male and 37% female) remained and were included in the primary analysis. There was no difference between the no retreatment and retreatment groups in terms of birthweight, gestational age, age at first injection, ROP stages, or number of involved clock hours. The retreatment group had a larger percentage of aggressive ROP (34% vs. 18%, P < 0.001) and greater percentage of zone 1 ROP (49 vs. 34%, P = 0.001) than the no retreatment group. Ranibizumab use was associated with a higher rate of retreatment than bevacizumab use (58% vs. 37%, P < 0.001), whereas the rate of retreatment was not associated with a specific dose of ranibizumab (R2 = 0.67, P = 0.32). Meanwhile, lower doses of bevacizumab were associated with higher rates of retreatment compared with the higher doses (R2 = 0.84, P = 0.01). There was a dose-specific trend with higher doses trending toward lower retreatments for bevacizumab., Conclusions: In a multicenter study of ROP patients initially treated with anti-VEGF therapy, ranibizumab and lower-dose bevacizumab use were associated with an increased rate of retreatment when compared with higher-dose bevacizumab., Financial Disclosure(s): Proprietary or commercial disclosure may be found after the references., (Copyright © 2022.

- Abstract
Background: Retinopathy of prematurity (ROP) and familial exudative vitreoretinopathy (FEVR) are two distinct pathologies of retinal angiogenesis with overlapping clinical features., Methods: Examination, multimodal imaging, and genetic testing were used to guide diagnosis and treatment., Results: We report a combined phenotype of X-linked FEVR and ROP in a 4-month-old girl with mosaic Turner syndrome with ring X chromosome born at 26 weeks gestational age. She was initially diagnosed with atypical ROP with a vitreous band causing a localized traction retinal detachment, inferotemporal to the macula in the right eye, vessels to posterior zone 2 with no clear ridge temporally in the left eye, and fluorescein leakage in both eyes. Due to the suspicion of concurrent FEVR, genetic testing using a vitreoretinopathy panel was performed which revealed a mosaic Turner syndrome associated with 45,X/46,X,r(X), subsequently confirmed by chromosome analysis. The deleted region in the ring X chromosome included the NDP and RS1 genes. The patient was treated with laser photocoagulation of the peripheral avascular retina and sub-Tenon's triamcinolone injection in both eyes, intravitreal injection of bevacizumab in the left eye, and pars plicata vitrectomy in the right eye., Conclusions: In premature neonates with atypical ROP, a clinical suspicion of concurrent FEVR or similar vasculopathy is important and genetic testing may elucidate a genetic etiology, which could influence management and prognosis. Turner syndrome can be connected with co-occurring Mendelian gene disorders, particularly in individuals with mosaicism. The concurrence of FEVR and ROP appears to result in atypical and possibly more severe phenotypes.

- Abstract
Purpose: To provide an overview of the impact of retinopathy of prematurity (ROP), and the challenges in the screening, diagnosis, and treatment of ROP worldwide., Methods: A comprehensive search was conducted using the PubMed database from January 2011 to October 2021 using the following keywords: retinopathy of prematurity, laser, and anti-vascular endothelial growth factor (VEGF). Data on patient characteristics, ROP treatment type, and recurrence rates were collected. The countries included in these studies were classified based on 2021-2022 World Bank definitions of high, upper-middle, lower-middle, and low-income groups. Moreover, a search for surgical outcomes for ROP and screening algorithms and artificial intelligence for ROP was conducted., Results: Thirty-nine studies met the inclusion criteria. ROP treatment and outcomes showed a trend towards intravitreal anti-VEGF injections as the initial treatment for ROP globally and the treatment of recurrent ROP in high-income countries. However, laser remains the treatment of choice for ROP recurrence in middle-income countries. Surgical outcomes for ROP stage 4A, 4B and 5 are similar worldwide. The incidence of ROP and ROP-related visual impairment continue to increase globally. Although telemedicine and artificial intelligence offer potential solutions to ROP screening in resource-limited areas, the current models require further optimization to reflect the global diversity of ROP patients., Conclusion: ROP screening and treatment paradigms vary widely based on country income group due to disparities in resources, limited access to care, and lack of universal guidelines.

- Abstract
Purpose: To report practice patterns of intravitreal injections of anti-VEGF for retinopathy of prematurity (ROP) and outcomes data with a focus on retreatments and complications., Design: Multicenter, international, retrospective, consecutive series., Subjects: Patients with ROP treated with anti-VEGF injections from 2007 to 2021., Methods: Twenfty-three sites (16 United States [US] and 7 non-US) participated. Data collected included demographics, birth characteristics, examination findings, and methods of injections. Comparisons between US and non-US sites were made., Main Outcome Measures: Primary outcomes included number and types of retreatments as well as complications. Secondary outcomes included specifics of the injection protocols, including types of medication, doses, distance from limbus, use of antibiotics, and quadrants where injections were delivered., Results: A total of 1677 eyes of 918 patients (43% female, 57% male) were included. Mean gestational age was 25.7 weeks (range, 21.2-41.5 weeks), and mean birth weight was 787 g (range, 300-2700 g). Overall, a 30-gauge needle was most commonly used (51%), and the quadrant injected was most frequently the inferior-temporal (51.3%). The distance from the limbus ranged from 0.75 to 2 mm, with 1 mm being the most common (65%). Bevacizumab was the most common anti-VEGF (71.4%), with a dose of 0.625 mg in 64% of cases. Overall, 604 (36%) eyes required retreatment. Of those, 79.8% were retreated with laser alone, 10.6% with anti-VEGF injection alone, and 9.6% with combined laser and injection. Complications after anti-VEGF injections occurred in 15 (0.9%) eyes, and no cases of endophthalmitis were reported. Patients in the United States had lower birth weights and gestational ages (665.6 g and 24.5 weeks, respectively) compared with non-US patients (912.7 g and 26.9 weeks, respectively) (P < 0.0001). Retreatment with reinjection and laser was significantly more common in the US compared with the non-US group (8.5% vs. 4.7% [P = 0.0016] and 55% vs. 7.2% [P < 0.001], respectively). There was no difference in the incidence of complications between the 2 geographic subgroups., Conclusions: Anti-VEGF injections for ROP were safe and well tolerated despite a variance in practice patterns. Infants with ROP receiving injections in the US tended to be younger and smaller, and they were treated earlier with more retreatments than non-US neonates with ROP., (Copyright © 2022 American Academy of Ophthalmology.

- Abstract
Purpose: To report a case of bilateral occlusive retinal vasculitis in a patient with autoimmunity., Methods: A case was analyzed and a literature review performed., Results: A 55-year-old woman with autoimmune diagnoses of Isaacs syndrome and inclusion body myositis (IBM) reported decreased vision for 3 months. A fundus examination showed peripheral intraretinal hemorrhages in the right eye and an inferotemporal subhyaloid hemorrhage with adjacent intraretinal hemorrhages and preretinal fibrosis in the left eye. Fluorescein angiography showed temporal peripheral leakage and capillary dropout in both eyes, consistent with occlusive vasculitis. Scatter laser treatment to peripheral areas of retinal nonperfusion was followed by an intravitreal bevacizumab injection. Four months later, vision had stabilized at 20/15 in both eyes and the peripheral leakage had resolved., Conclusions: This patient developed retinal vasculitis associated with the rare autoimmune neuromuscular disorders of Isaacs syndrome and IBM. An extensive workup showed the most plausible mechanism for the vasculitis was autoimmunity with a history of previously elevated antibodies levels associated with the antiphospholipid syndrome., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

- Abstract
Importance: Literature and anecdotal evidence suggest a relationship between male sex and retinopathy of prematurity (ROP). It is not known whether a difference, if present, is sex-related pathophysiologic predisposition or sex difference in meeting ROP screening criteria., Objective: To evaluate the association of sex with the development of treatment-warranted ROP., Data Sources: PubMed, Embase, and Web of Science databases were searched from 2000 to 2022. The search strategy used keywords including retinopathy of prematurity or ROP or retrolental fibroplasia and treatment or anti-VEGF or bevacizumab or ranibizumab or aflibercept or conbercept or laser or cryotherapy and gender or sex or male or female and medical subject headings terms., Study Selection: All studies reporting on treatment with anti-vascular endothelial growth factor, laser photocoagulation, and/or cryotherapy for ROP were identified. Studies reporting sex distribution in the treatment group were included in the meta-analysis. Exclusion criteria included case reports, case series of fewer than 10 treated patients, systematic reviews, conference abstracts, letters to the editor, animal studies, and non-English records., Data Extraction and Synthesis: Two reviewers independently screened and extracted the data following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The proportions of treated male and female infants were combined using random-effects meta-analysis., Main Outcomes and Measures: Numbers and percentages of male and female infants treated for ROP., Results: Of 11 368 identified studies, 316 met inclusion criteria, yielding a total of 31 026 treated patients. A higher percentage of male infants were treated for ROP (55% [95% CI, 0.54%-0.55%]), with low heterogeneity between studies (I2 = 34%; P < .001). Thirty-eight studies reported sex distribution in the screened population (170 053 patients; 92 612 [53%] male vs 77 441 [47%] female). There was no significant difference in the odds of receiving treatment between screened male and female infants (pooled odds ratio, 1.04 [95% CI, 0.91-1.18]; P = .67)., Conclusions and Relevance: More male infants are treated for ROP than female infants. This could be due to a known relative pathophysiological fragility of preterm male infants in addition to a difference in ROP screening rates, with more male infants meeting the criteria than female infants. These findings have implications for future studies and may prompt more careful clinical monitoring of male neonates.

Hoyek S, Lin LY, Kozek LK, Gonzalez E, Rajabi F, and Patel NA
- Abstract
Best vitelliform macular dystrophy (BVMD) is a slowly progressive macular disease caused by a pathogenic variant of the Bestrophin ( BEST1 ) gene. Examination coupled with multimodal imaging and genetic testing are used to guide diagnosis and treatment. A 12-year-old girl was examined for decreased vision in the left eye and showed bilateral "egg-yolk"-like macular lesions with choroidal neovascularization (CNV) in the left eye. Six months later, she experienced decreased vision with appearance of CNV on optical coherence tomography angiography in the right eye. Injections of anti-vascular endothelial growth factor helped restore vision from 20/125 to 20/20 in the right eye with stabilization of her left eye (vision 20/40). Genetic testing revealed c.851A > G (p.Tyr284Cys), a heterozygous variant of the BEST1 gene. The same variant was found in her father, who was initially misdiagnosed with toxoplasmosis due to a peripheral retinal lesion in the left eye. This is the first report of bilateral consecutive CNV secondary to BVMD. Additionally, it highlights the likely pathogenic role of a novel variant of the BEST1 gene., (Copyright © 2022 Baylor University Medical Center.)

- Abstract
Purpose: To study the corneal flattening effect of cross-linking (CXL) overtime and to look for a potential association with preoperative topographic variables and the central depth of demarcation line (DDL)., Methods: 201 eyes of 146 patients (mean age of 31.2 ± 7.3 years) with progressive keratoconus who underwent CXL between June 2007 and December 2012 were enrolled in this retrospective study. Follow-up visits were performed at different time intervals for at least 5 years. Preoperative parameters and depth of demarcation line were collected from LaserVision ophthalmology center in Lebanon. Corneal flattening was defined by a change in postoperative Kmax (ΔKmax) greater than 1.00 D., Results: ΔKmax increased from 50.25% to 61.69%, from first to last follow-up visits. The only factor significantly correlated to ΔKmax during all follow-up visits was preoperative maximum keratometry (Kmax) especially when greater than 50.00 D (OR, 1.92; 95% CI, 1.10-3.34). All eyes showed a corneal demarcation line (mean central depth (DDL): 217.11 ± 26.54 μm), with no statistically significant correlation between DDL and ΔKmax., Conclusion: CXL effect on cornea can be cumulative overtime and delayed flattening occurs in some cases. ΔKmax is positively correlated with preoperative Kmax and no association was found between ΔKmax and DDL. Therefore, DDL may not be a valid measure for the efficacy of CXL.

- Abstract
ALK inhibitors are a new group of tyrosine kinase inhibitors, highly efficient in the treatment of non-small-cell lung carcinoma. However, these targeted therapies can induce various adverse effects, including ocular toxicity. To date, few articles reporting ophthalmological side effects of ALK inhibitors have been published. In this review, we aim to describe the different side effects and to collect information regarding the causes behind the discrepancy between the reported rates of visual disorders. Frequent ocular side effects of ALK inhibitors included flashes, post-flashbulb effect, stripes, photopsia, accommodation disorder, presbyopia, reduced visual acuity and blurred vision. Optic neuropathy, vitreous floaters, diplopia, cataract and macular edema were also reported.
