Purpose: To compare efficacy and safety of a more intense regimen versus a standard one for retreatment of neovascular age-related macular degeneration (AMD) during the early period of verteporfin therapy (VT).Design: Prospective, randomized, multicenter clinical trial.Participants: Two hundred three patients with predominantly classic choroidal neovascularization (CNV) secondary to AMD.Methods: During the first 6 months of VT, patients underwent retreatment every 2 (group A) or 3 (group B) months. After 6 months, both groups underwent retreatment every 3 months for as long as CNV activity was documented.Main Outcome Measures: Best-corrected visual acuity (BCVA) measured every 6 months, mean number of treatments per patient during 24 months' follow-up, proportions of patients in each group losing at least 3 lines of vision or gaining at least 1 line, greatest linear dimension (GLD) of the lesion as documented by fluorescein angiography every 6 months, and relationship between initial lesion size and BCVA.Results: At all follow-up times, mean BCVAs were similar for groups A and B. Mean numbers of photodynamic therapy treatments were similar for both groups (4.07 vs. 4.36; P = 0.451, paired t test). A lower proportion (51.9% vs. 56.7%) of patients in group A had lost at least 3 lines of vision at 24 months. Groups A and B had similar increases in mean lesion size from baseline to 24 months (2104-3056 mu m and 2179-3020 mu m). At 24 months, patients in group A with a baseline lesion GLD of :2000 mu m (P = 0.032); differences also were significant for group A with GLD of
