Abstract

PurposeTo evaluate the functional outcomes of patients with polypoidal choroidal vasculopathy (PCV) who underwent intravitreal ranibizumab (IVR) treatment, compared with photodynamic therapy (PDT), after at least 2 years.MethodsWe retrospectively studied all the treatment-naïve patients with PCV who were scheduled to undergo IVR or PDT between August 2005 and June 2010. All the patients who had a 2-year or longer follow-up period were included in the study. The best-corrected visual acuity (BCVA) in the two groups was compared before treatment and at 3, 6, 12, 18 and 24 months after the initial treatment. The regression of the polyps was also assessed using indocyanine green angiography.ResultsA total of 77 patients were included in this study. Thirty-three eyes were treated with IVR, and 44 eyes were treated with PDT. Although no significant differences between the two groups were observed at baseline or at 3, 6, and 12 months after treatment, a significantly better BCVA was seen in the IVR group, compared with the PDT group, at 18 and 24 months after treatment (P=0.035 and P=0.021, respectively). No significant difference in the rate of polyp regression was observed between the two groups (P=0.092).ConclusionIVR was well tolerated and maintained or improved the vision of patients with PCV, compared with PDT, as evaluated at 2-year follow-up examinations. PDT for the treatment of PCV might result in unfavorable outcomes, with no superiority to achieving the involution of polyps. © 2013 Macmillan Publishers Limited All rights reserved.
