We treated 42 eyes of age-related macular degeneration by dye-enhanced laser photocoagulation. All the eyes had subfoveal choroidal neovascularization (CNV) by fluorescein and indocyanine green (ICG) angiography. Eyes were treated by diode laser at wavelength of 810nm 5 minutes after injection of 40 mg of ICG into the antecubital vein. An attempt was made to ablate the whole CNV at the power output of 300 to 500mW, spot size of 300 to 500 u m and duration of 0.5 seconds. At 3 months after treatment, the visual acuity improved by 2 lines or more in 10 eyes (24%), remained unchanged in 20 eyes (47%) and decreased by 2 lines or more in 12 eyes (29%) . At 6 months after treatment, visual acuity improved in 10 of 32 eyes (31%), remained unchanged in 15 eyes (47%) and decreased in 7 eyes (22%). The findings show the efficacy of dye-enhanced diode laser photocoagulation for subfoveal choroidal neovascularization in age-related macular degeneration.
