Abstract

Purpose: To evaluate the safety and efficacy of intravitreal ranibizumab with or without photodynamic therapy (PDT) in the treatment of polypoidal choroidal vasculopathy (PCV) in Korean patients. Methods: A retrospective chart review of 22 patients (24 eyes) with PCV was conducted. Nine eyes were treated with intravitreal ranibizumab combined with a single session of PDT (group 1), and 15 eyes were treated only with ranibizumab (group 2). Such clinical evaluations as best-corrected Snellen visual acuity, central retinal thickness (CRT) by optical coherence tomography (OCT), fluorescein angiography (FA) and indocyanine green angiography (ICGA) were done at baseline, 1, 3, 6, 9 and 12 months after the first injections. Ranibizumab was reinjected on an as-needed basis guided by OCT, FA and ICGA, or at the doctor’s discretion. Results: The mean follow-up duration was 22.5 months (range 12–37). The mean best-corrected visual acuity (logMAR) improved, and the mean CRT decreased throughout 12 months in both groups; no statistically significant difference between the groups was found (p = 0.327, p = 0.073, respectively). The number of ranibizumab injections was not significantly different either (p = 0.555). Conclusions: Intravitreal ranibizumab with or without PDT for PCV in Korean patients resulted in visual and anatomical improvement over the 1-year follow-up period.
