Faricimab in Neovascular AMD Complicated by Pigment Epithelium Detachment: An AI-Assisted Evaluation of Early Morphological Changes.

INTRODUCTION: This study investigates the early temporal changes in pigment epithelial detachment (PED) morphology following treatment with faricimab in patients with neovascular age-related macular degeneration (nAMD). Utilizing an artificial intelligence (AI)-assisted approach, we provide a detailed quantification and characterization of the dynamics of these morphological changes. METHODS: A prospective observational study was conducted on 22 eyes from 22 treatment-naïve patients with nAMD-associated PED (presenting either type 1 or type 3 macular neovascularization). Participants were administered intravitreal faricimab (6 mg) at baseline and at days 30, 60, and 90. Comprehensive ophthalmic evaluations and spectral-domain optical coherence tomography (SD-OCT) imaging were conducted at baseline and at seven additional follow-up visits on days 1, 7, 14, 30, 60, 90, and 120. An AI-based automated segmentation algorithm was utilized to precisely quantify changes in PED volume, alongside intraretinal (IRF) and subretinal fluid (SRF) volumes, at each time point. RESULTS: Treatment with faricimab resulted in a significant reduction in mean PED volume, with an average decrease of 12% at day 1, 29% at day 7, 51% at day 14, 68% at day 30, 72% at day 60, 79% at day 90, and 84% at day 120 (p < 0.0001 for all time points). Similarly rapid and marked reductions were noted in both mean IRF (23.5% at day 1, 90.7% at day 14) and SRF (14.4% at day 1, 91.2% at day 14) volumes. The study also showed a statistically significant improvement in best-corrected visual acuity (BCVA) over the follow-up period, correlating with the reduction in PED volume. CONCLUSION: Faricimab demonstrates early and significant efficacy in improving PED architecture in patients with nAMD. The rapid morphological improvements observed in this study suggest faricimab may represent a valid therapeutic option for PEDs associated with nAMD.

Submacular hemorrhage during neovascular age-related macular degeneration: a meta-analysis and meta-regression on the use of tPA and anti-VEGFs.

BACKGROUND: Submacular hemorrhage (SMH) associated with neovascular age-related macular degeneration (nAMD) precipitates rapid visual decline and impacts quality of life. Treatments vary, but combined recombinant tissue plasminogen activator (tPA) and anti-vascular endothelial growth factor (anti-VEGF) therapy has gained prominence as a viable treatment option. OBJECTIVES: This study aims to evaluate the efficacy of the combination of tPA and anti-VEGF. METHODS: We conducted a systematic review meta-analysis following PRISMA guidelines, focusing on studies examining tPA and anti-VEGF therapy in SMH secondary to nAMD. Outcomes measured were change in best-corrected visual acuity (BCVA) and success rate of SMH displacement. Meta-regression assessed the relative efficacy of intravitreal and subretinal delivery. RESULTS: Out of 257 initial reports, 22 studies involving 29 patient populations met inclusion criteria. Our analysis showed significant improvement in BCVA and a high rate of successful SMH displacement with combined tPA and anti-VEGF therapy. No significant differences were found between subretinal and intravitreal tPA administration. Furthermore, when evaluating the effects of subretinal versus intravitreal anti-VEGF administration in patients treated with subretinal tPA, the results indicated similar efficacy. CONCLUSIONS: Combined tPA and anti-VEGF therapy is effective in managing SMH in nAMD patients, significantly improving visual acuity and SMH displacement. The location of tPA and anti-VEGF delivery did not significantly impact outcomes.

Update on coronavirus disease 2019: Ophthalmic Manifestations and Adverse Reactions to Vaccination.

The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 was one of the most devastating public health issues in recent decades. The ophthalmology community is as concerned about the COVID-19 pandemic as the global public health community is, as COVID-19 was recognized to affect multiple organs in the human body, including the eyes, early in the course of the outbreak. Ophthalmic manifestations of COVID-19 are highly variable and could range from mild ocular surface abnormalities to potentially sight and life-threatening orbital and neuro-ophthalmic diseases. Furthermore, ophthalmic manifestations may also be the presenting or the only findings in COVID-19 infections. Meanwhile, global vaccination campaigns to attain herd immunity in different populations are the major strategy to mitigate the pandemic. As novel vaccinations against COVID-19 emerged, so were reports on adverse ophthalmic reactions potentially related to such. As the world enters a post-pandemic state where COVID-19 continues to exist and evolve as an endemic globally, the ophthalmology community ought to be aware of and keep abreast of the latest knowledge of ophthalmic associations with COVID-19 and its vaccinations. This review is a summary of the latest literature on the ophthalmic manifestations of COVID-19 and the adverse ophthalmic reactions related to its vaccinations.
