Abstract

Purpose: The aim of this study was clarify the efficacy of combination therapy of intravitreal ranibizumab (IVR) injections and photodynamic therapy (PDT) in patients with symptomatic retinal angiomatous proliferation (RAP) over 24 months.

Methods: We retrospectively reviewed 37 naïve eyes of 31 patients treated with three consecutive monthly IVR injections (0.5 mg/0.05 ml) and PDT and followed for at least 24 months.

Results: The mean logarithm of the minimum angle of resolution best-corrected visual acuity levels improved significantly (P < 0.0001) from 0.63 at baseline to 0.39 at 24 months. Geographic atrophy (GA) involving the fovea developed in nine (24%) eyes, with a significant (P = 0.036) decrease in VA at 24 months and a high (100%) prevalence of reticular pseudodrusen (RPD) at baseline. Complete occlusion of the retinal–retinal anastomosis seen in 35 eyes was achieved in 33 eyes at month 24. The central retinal thickness decreased significantly (P < 0.0001) from 415 to 129 μm at 24 months. The mean number of treatments during 24 months was 2.5 PDT and 5.5 IVR injections.

Conclusions: Combination therapy comprising IVR injections and PDT is generally effective in maintaining or improving VA and retinal morphology within 2 years in eyes with RAP, except for eyes with baseline RPD, which are likely to develop GA in the fovea resulting in reduced VA.
