Twenty-seven eyes with pachychoroid neovasculopathy and sixty-three eyes with neovascular AMD. All patients received three initial monthly, followed by bimonthly, IVA injections.Results: Twelve months after initial treatment, the mean best-corrected visual acuity (BCVA) had improved both in pachychoroid neovasculopathy (from 0.28 to 0.14 logMAR; P = 0.001) and neovascular AMD (from 0.40 to 0.29 logMAR; P < 0.001). Twelve months after initial treatment, eyes with pachychoroid neovasculopathy exhibited decreased mean central retinal thickness (CRT) and subfoveal choroidal thickness (both, P < 0.001) and presence of polyps (P = 0.039) and improved integrity of external limiting membrane (ELM) (P = 0.008) and ellipsoid zone band (P = 0.001). At the 12-month follow-up, 77% and 68% of eyes with pachychoroid neovasculopathy and neovascular AMD, respectively, exhibited dry macula (P = 0.30). Baseline CRT was correlated with 12-month BCVA in eyes with pachychoroid neovasculopathy (P = 0.02). In eyes with neovascular AMD, CRT (P = 0.005) and presence of intact ELM (P = 0.007) were significant predictors of 12-month BCVA.Conclusion: Periodic IVA injection leads to anatomical and functional improvement in eyes with pachychoroid neovasculopathy and in eyes with neovascular AMD.Keywords: age-related macular degeneration, aflibercept, pachychoroid neovasculopathy, choroidal thickness |
