Development of Age-Related Macular Degeneration (AMD) in the Fellow Eye of Patients with AMD Treated by Treat-and-Extend Intravitreal Therapy with Aflibercept

摘要

Purpose: To evaluate the development of neovascular age-related macular degeneration (nAMD) in the fellow eye in patients with unilateral nAMD treated by a treat-and-extend (TAE) regimen with intravitreal aflibercept injections. Methods: We retrospectively studied 104 patients with treatment-na?ve unilateral nAMD. We assessed best-corrected visual acuity (BCVA) and exudative changes in the treated eyes and development of nAMD in the fellow eye for 2 years. Results: The subjects included 46 patients with typical AMD (tAMD), 44 with polypoidal choroidal vasculopathy (PCV), and 14 with retinal angiomatous proliferation (RAP). BCVA was significantly improved after the loading phase in all subtypes. Forty-six patients (44.2%) had no recurrence within 2 years after the loading phase, including 12 (26.1%) with tAMD, 23 (52.2%) with PCV, and 11 (78.6%) with RAP ( p p Conclusions: Patients with RAP had significantly more frequent development of nAMD in the fellow eye compared to other subtypes, while they showed significantly less recurrence during the TAE regimen with intravitreal aflibercept injections. Development of nAMD in the fellow eye should be monitored in RAP when the injection interval is extended.
