PURPOSE: To evaluate early changes after photodynamic therapy (PDT) in patients with age-related macular degeneration (AMD) by optical coherence tomography (OCT). DESIGN: Prospective interventional case series. METHODS: PDT was performed on 20 eyes of 20 patients who presented with subfoveal choroidal neovascularization (CNV) attributable to AMD. OCT was used to evaluate changes at 2,12,and 24 hours and at 3,7,15,and 30 days after therapy. RESULTS: In the first 24 hours,OCT showed an increase in the subretinal fluid (SF) in all eyes and an increase in intraretinal fluid (IF) in 13 eyes. On the 15th day and the 30th day after therapy,reduction of SF and IF was observed in almost all eyes. CONCLUSIONS: Serial OCT evaluation of patients with subfoveal CNV attributable to AMD suggests that the initial response after PDT is an increase in SF and IF.

METHODS: PDT was performed on 20 eyes of 20 patients who OCT was used to evaluate changes at 2, 12, and 24 hours and at 3, 7, 15, and 30 days after therapy. RESULTS: OCT was used to evaluate changes at 2, 12 and 24 hours and at 3, an increase in the subretinal fluid (SF) in all eyes and an increase in intraretinal fluid (IF) in 13 eyes. On the 15th day and the 30th day after therapy, reduction of SF and IF was observed in almost all eyes. CONCLUSIONS: Serial OCT evaluation of patients with subfoveal CNV attributable to AMD suggests that the initial response after PDT is an increase in SF and IF.
