Purpose: The purpose of this study was to compare photodynamic therapy (PDT), ranibizumab, and ranibizumab with PDT in polypoidal choroidal vasculopathy.

Methods: In this retrospective comparative study, 30 eyes of 30 patients with polypoidal choroidal vasculopathy were assigned to 1 of the 3 groups. The patients in Group 1 (n = 11) received 1 session of PDT. The patients in Group 2 (n = 10) received 3 monthly intravitreal injections of 0.5 mg ranibizumab, and the patients in Group 3 (n = 9) received 1 session of PDT and 3 injections of 0.5 mg ranibizumab. Retreatment, with the same therapeutic scheme in each group, was considered in case of leaking polyps on the indocyanine green angiography in Groups 1 and 3 and persistence or recurrence of subretinal fluid, intraretinal fluid, and/or hemorrhages in Group 2.

Results: All the patients completed 12 months of follow-up. The visual acuity in the patients of Group 1 improved by 0.25 logarithm of the minimum angle of resolution units (P < 0.001), whereas the differences in the visual acuity in the other 2 groups were not statistically significant (0.04 logarithm of the minimum angle of resolution, P = 0.8118 in Group 2 and 0.18 logarithm of the minimum angle of resolution, P > 0.05 in Group 3). Of the patients in Group 1, 45.45% gained more than 3 lines (P = 0.0056), whereas no patient in Groups 2 and 3 experienced such a difference. No patient in Group 1 and 11.1% (n = 1) in Group 3 had angiographically evident polyps at 12 months, whereas 90% (n = 9) of the patients in Group 2 had persistent leakage. No extensive submacular hemorrhage or other complications were noted during the follow-up period.

Conclusion: Photodynamic therapy resulted in a significantly better outcome at the end of the follow-up, whereas the patients who received ranibizumab or PDT and ranibizumab experienced a stabilization of the disease.

In this retrospective study, ranibizumab alone and with photodynamic therapy resulted in stabilization of polypoidal choroidal vasculopathy, whereas photodynamic therapy resulted in a significantly better outcome at the end of the follow-up.
