Background/Objectives To assess the safety and efficacy of avacincaptad pegol (ACP), a C5 inhibitor, for geographic atrophy (GA) secondary to age-related macular degeneration (AMD) over an 18-month treatment course. Subjects/Methods This study was an international, prospective, randomized, double-masked, sham-controlled, phase 2/3 clinical trial that consisted of 2 parts. In part 1, 77 participants were randomized 1:1:1 to receive monthly intravitreal injections of ACP 1 mg, ACP 2 mg, or sham. In part 2, 209 participants were randomized 1:2:2 to receive monthly ACP 2 mg, ACP 4 mg, or sham. The mean rate of change of GA over 18 months was measured by fundus autofluorescence. Results Compared with their respective sham cohorts, monthly ACP treatment reduced the mean GA growth (square root transformation) over 18 months by 28.1% (0.168 mm, 95% CI [0.066, 0.271]) for the 2 mg cohort and 30.0% (0.167 mm, 95% CI [0.062, 0.273]) for the 4 mg cohort. ACP treatment was generally well tolerated over 18 months, with most ocular adverse events (AEs) related to the injection procedure. Macular neovascularization (MNV) was more frequent in both 2 mg (11.9%) and 4 mg (15.7%) cohorts than their respective sham control groups (2.7% and 2.4%). Conclusions Over this 18-month study, ACP 2 mg and 4 mg showed continued reductions in the progression of GA growth compared to sham and continued to be generally well tolerated. A pivotal phase 3 GATHER2 trial is currently underway to support the efficacy and safety of ACP as a potential treatment for GA.

Objective Post-hoc analysis to compare the outcomes of brolucizumab 6 mg vs. aflibercept 2 mg in neovascular age-related macular degeneration (nAMD) patients with early persistent retinal fluid in HAWK and HARRIER. Methods After 3 monthly loading doses, brolucizumab-treated eyes (N = 730) received injections every 12 weeks (q12w) or q8w if disease activity was detected. Aflibercept-treated eyes (N = 729) received fixed q8w dosing. Early persistent fluid was defined as the presence of subretinal fluid and/or intraretinal fluid up to Week 12. Results A lower proportion of brolucizumab patients had early persistent retinal fluid compared with aflibercept (11.2% (n = 82) vs. 19.2% (n = 140)). In these patients, 34.1% of the brolucizumab-treated group achieved a ≥ 15 ETDRS letter gain in best corrected visual acuity (BCVA) from baseline at Week 96 compared with 20.7% of the aflibercept-treated group. Brolucizumab achieved numerically better BCVA outcomes (Week 96: brolucizumab, +6.4 letters; aflibercept, +3.7 letters) and significantly greater central subfield thickness reductions versus aflibercept from baseline through Week 96 (Week 96: −202 µm vs. −145 µm; p = 0.0206). Brolucizumab demonstrated an overall favourable benefit/risk profile in this patient cohort. In their unmasked, post-hoc review, the Safety Review Committee identified two cases of retinal vasculitis and no cases of retinal vascular occlusion in the brolucizumab arm; no cases of retinal vasculitis or retinal vascular occlusion were identified in the aflibercept arm. Conclusion In this analysis, anatomical and visual outcomes were better with brolucizumab compared with aflibercept. Brolucizumab may therefore achieve greater disease control than aflibercept in nAMD patients with early persistent retinal fluid.

Neoplasms of the retinal pigment epithelium (RPE) are rare tumors that can simulate choroidal melanoma, but clinical and imaging characteristics often differentiate these lesions. We report a 70-year-old male with an abruptly elevated pigmented lesion that arose at the site of congenital hypertrophy of the RPE and demonstrated associated exudation, as well as feeding and draining vessels, suggestive of RPE adenoma. Optical coherence tomography showed retinal elevation with serous retinal detachment adjacent to the mass, and ultrasonography revealed an abruptly elevated, moderately echodense mass of 6.4-mm thickness. Fluorescein ­angiography showed early tumor hypofluorescence, late ­tumor hyperfluorescence with staining and leakage, and ­retinal vessels buried under the mass, suggestive of a retinal tumor. The patient was monitored with the presumed diagnosis of RPE adenoma, but 3 months later, the growth was documented and fine-needle aspiration biopsy revealed choroidal melanoma. Management with I-125 plaque radiotherapy was performed leading to tumor regression and a thickness of 4.6 mm.

Importance Outcome data are limited regarding early experience with brolucizumab, the most recently approved anti–vascular endothelial growth factor (VEGF) agent for the treatment of neovascular age-related macular degeneration (nAMD). Objective To report clinical outcomes after intravitreous injection (IVI) of brolucizumab, 6 mg, for nAMD. Design, Setting, and Participants This retrospective case series conducted at 15 private or academic ophthalmological centers in the United States included all consecutive patients with eyes treated with brolucizumab by 6 retina specialists between October 17, 2019, and April 1, 2020. Exposures Treatment with brolucizumab IVI, 6 mg. Main Outcomes and Measures Change in mean visual acuity (VA) and optical coherence tomography parameters, including mean central subfield thickness and presence or absence of subretinal and/or intraretinal fluid. Secondary outcomes included ocular and systemic safety. Results A total of 172 eyes from 152 patients (87 women [57.2%]; mean [SD] age, 80.0 [8.0] years) were included. Most eyes (166 [96.5%]) were not treatment naive, and 65.7% of these eyes (109 of 166) were switched from the prior anti-VEGF agent because of persistent fluid detected on optical coherence tomography scans. Study eyes received a mean (SD) of 1.46 (0.62) brolucizumab IVIs. The mean (SD) VA prior to starting brolucizumab was a 64.1 (15.9) Early Treatment Diabetic Retinopathy Study (ETDRS) letter score (Snellen equivalent, 20/50) and was a 63.3 (17.2) ETDRS letter score (Snellen equivalent, 20/63) at the last study evaluation (mean difference, 0.8; 95% CI, −2.7 to 4.3;P = .65). When analyzed by number of brolucizumab IVIs, the presence or absence of fluid prior to starting brolucizumab, or the presence or absence of intraocular inflammation after receiving brolucizumab, there was no difference in mean VA prior to starting brolucizumab compared with after brolucizumab IVIs or at the final study evaluation. The mean (SD) central subfield thickness in all eyes prior to starting brolucizumab was 296.7 (88.0) μm and was 269.8 (66.5) μm at the last study examination (mean difference, 26.9 µm; 95% CI, 9.0-44.7 µm;P = .003). Intraocular inflammation was reported in 14 eyes (8.1%) and was self-limited and resolved without treatment in almost half those eyes (n = 6). One previously reported eye (0.6%) had occlusive retinal vasculitis and severe loss of vision. Conclusions and Relevance In this analysis of brolucizumab IVI for nAMD, VA remained stable, with a reduction in central subfield thickness. Intraocular inflammation events ranged from mild with spontaneous resolution to severe occlusive retinal vasculitis in 1 eye.

PurposeTo investigate the progression characteristics of ellipsoid zone (EZ) loss in eyes with macular telangiectasia type 2 (MacTel) as reflected by area and linear measurements, and their relevance for visual acuity.MethodsParticipants were selected from the MacTel Study cohort. Linear and area measurements of EZ loss were performed in Spectral-Domain Optical Coherence Tomograph (SD-OCT) volume scans. Progression characteristics and correlations between linear and area measurements were analysed using linear mixed effects models.ResultsA total of 134 eyes of 70 patients were included (85 eyes with follow-up, mean 4.7years, range: 1.4-8years). Ellipsoid zone (EZ) loss significantly progressed at a mean annual increment of 0.057mm2 (p=0.005). The progression rate was non-linear and interacted significantly with initial EZ lesion size indicating an exponential growth before reaching a plateau. There was a strong heterogeneity in area sizes between fellow eyes. EZ break length had a significant linear effect on EZ break area (b=1.06, p&nbsp

Purpose To report expanded SD-OCT findings of HCQ retinopathy that may assist the clinician in earlier diagnosis. To characterize structural changes of HCQ retinopathy with SD-OCT after drug cessation. Methods Setting: Private practice and academic institution. Patient Population: Patients at New England Eye Center and Ophthalmic Consultants of Boston in Boston, MA diagnosed with HCQ retinopathy and followed after drug cessation. Retrospective clinical data review by the Boston Image Reading Center. Main Outcome Measures: SD-OCT findings suggestive of HCQ retinopathy before parafoveal ellipsoid disruption. Change in SD-OCT morphological appearance and retinal thickness of each of the nine subfields corresponding to the Early Treatment of Diabetic Retinopathy Study areas. Results Thirty eyes with HCQ retinopathy were followed with SD-OCT after drug cessation. Findings before disruption of the parafoveal EZ included parafoveal outer nuclear layer (ONL) thinning, disruption of the parafoveal interdigitation zone, and reduced reflectivity of the parafoveal EZ. In early toxicity, 75 % developed progression after drug cessation, including disruption of the parafoveal EZ and retinal pigment epithelium and thinning of the ONL. Eyes with obvious toxicity had greater inferior outer ring thinning 12 months after drug cessation compared to early toxicity (p = 0.002, 95 % CI −2 to −8 μm). In obvious toxicity, the nasal inner subfield showed more thinning than the temporal inner subfield at 12 months after drug cessation (p = 0.018, 95 % CI −1 to −8 μm). Conclusions Once HCQ retinopathy is diagnosed and the medication is discontinued, structural retinal changes commonly occur.

Objective To determine the rate of metastasis of uveal melanoma on the basis of tumor thickness in millimeters. Methods Retrospective medical record review. Results The mean (median) patient age was 58 (59) years. A total of 8033 eyes were examined. Of the 285 eyes with iris melanoma, the mean tumor thickness was 2.7 mm and metastasis occurred in 0.5%, 4%, and 7% at 3, 5, and 10 years, respectively. Of the 492 eyes with ciliary body melanoma, the mean tumor thickness was 6.6 mm and metastasis occurred in 12%, 19%, and 33% at 3, 5, and 10 years, respectively. Of the 7256 eyes with choroidal melanoma, the mean tumor thickness was 5.5 mm and metastasis occurred in 8%, 15%, and 25% at 3, 5, and 10 years, respectively. For all uveal melanoma, metastasis at 5, 10, and 20 years was 6%, 12%, and 20% for small melanoma (0-3.0 mm thickness), 14%, 26%, and 37% for medium melanoma (3.1-8.0 mm), and 35%, 49%, and 67% for large melanoma (>8.0 mm). More specifically, metastasis per millimeter increment at 10 years was 6% (0-1.0 mm thickness), 12% (1.1-2.0 mm), 12% (2.1-3.0 mm), 16% (3.1-4.0 mm), 27% (4.1-5.0 mm), 28% (5.1-6.0 mm), 29% (6.1-7.0 mm), 41% (7.1-8.0 mm), 50% (8.1-9.0 mm), 44% (9.1-10.0 mm), and 51% (>10.0 mm). Clinical factors predictive of metastasis by multivariate analysis included increasing patient age, ciliary body location, increasing tumor diameter, increasing tumor thickness, having a brown tumor, and the presence of subretinal fluid, intraocular hemorrhage, or extraocular extension. Conclusion Increasing millimeter thickness of uveal melanoma is associated with increasing risk for metastasis.
