We performed laser photocoagulation for choroidal neovascularization (CNV) in 40 eyes of 40 patients of age-related macular degeneration with retinal pigment epithelial detachment, guided by indocyanine green angiography (IA) . During the follow-up period of more than 6 months, visual acuity was unchanged or improved in 32 eyes (80%) . Exudative lesion was resolved in 26 eyes (65%) with or without additional laser treatment. IA was repeated after initial treatment in 28 of the 40 eyes. IA showed resolution of the focal spot in 13 eyes (46%) but residual or recurrent focal spot in 15 eyes (54%) . In these 15 eyes, the focal spot was detected at foveal side of laser scar in 11 eyes but developed apart from the initial focal spot in 4 eyes. These focal spots occurred within the plaque. We performed additional laser photocoagulation in 11 of the 15 eyes except 4 eyes with subfoveal focal spots and achieved resolution of focal spots. IA improved success rate in laser treatment for CNV with retinal pigment epithelial detachment. Because residual or recurrent CNV often occur, repeated IA is necessary after initial laser photocoagulation.
