Abstract

Purpose: We compared 1-year outcomes of 1 + pro re nata (PRN) versus 3 + PRN of intravitreal aflibercept injection (IAI) for age-related macular degeneration (AMD). Methods: Forty-two eyes with naïve AMD received 3 + PRN IAI treatment and 47 eyes with naïve AMD received 1 + PRN IAI treatment. Visual acuity (VA), central retinal thickness (CRT), and central choroidal thickness (CCT) and number of administered IAIs during 12 months were compared. Results: VAs improved, and CRTs reduced significantly at any given month from baseline in both groups (p < 0.01, respectively). CCT reduced significantly at 3 months in the 3 + PRN group (p = 0.024) but not in the 1 + PRN group. The 1 + PRN group received fewer injections than the 3 + PRN group (p < 0.01). Conclusions: Aflibercept leads to equivalent VA and morphologic retinal improvement without administering 3 injections.
