Purpose: To evaluate retreatment indications/morphologic responses to ranibizumab monotherapy and combination with verteporfin photodynamic therapy (PDT). Methods: A total of 40 patients received 3 monthly intravitreal ranibizumab 0.3 mg injections combined with either PDT or sham PDT at baseline (1:1) followed by as-needed ranibizumab based on predetermined vision/anatomical criteria. Results: Retreatment criteria were visual acuity (VA) loss (59%/58%), central retinal thickness (CRT) increase (27%/26%), or both (14%/16%). One month before retreatment, intraretinal cysts (IRC) were present in 84%/74%, subretinal fluid (SRF) in 70%/63%, and at least one of them in 84%/89% of eyes. A significant decrease in mean leakage area, IRC, and SRF as well as a reduction in presence of hemorrhages and hard exudates occurred in both treatment groups at 12 months (compared to baseline). Conclusions: Retreatment indications were mostly based on VA loss, probably due to the quantitative optical coherence tomography criterion. Intraretinal cysts and SRF were earlier predictors for recurring choroidal neovascularization (CNV) activity than CRT/VA changes. Both treatment strategies were equally potent in reducing CNV activity.
