Abstract

The aim of the present study was to evaluate the efficacy of combination treatment with intravitreal ranibizumab (IVR) injection and photodynamic therapy (PDT) for polypoidal choroidal vasculopathy (PCV). A total of 64 patients with PCV were included in the present study, which were divided into the IVR monotherapy group (Group A) and combination treatment groups (Groups B‑D) with different treatment intervals. All subjects were followed‑up at 1, 3, 6 and 12 months following treatment, and subjected to the detection of best‑corrected visual acuity (BCVA) and central foveal thickness (CFT). Compared with the monotherapy group, more significant BCVA improvement was observed for the combination treatment groups, with the most evident effect exhibited in Group C. At the end of the follow‑up period, visual acuity improvement rates were markedly elevated in the combination treatment groups, as compared with the monotherapy group. According to optical coherence tomography, the CFT for the combination treatment groups was thinner than the monotherapy group. Among the combination groups, CFT improvement for Group C was superior to other groups. Fundus angiography demonstrated that, compared with monotherapy, combination treatment may significantly promote the regression and prevent the recurrence of polyps and BVN. The most efficient effectiveness was observed for Group C. In addition, combination treatment may significantly reduce the IVR injection numbers required to treat PCV. Patients receiving combination treatment with IVR injection and PDT have greater vision improvements, reduced macular degeneration and decreased injection numbers. Combination therapy may therefore, represent an effective and safe therapeutic strategy for PCV clinical treatment.
