Abstract
PURPOSE: To determine visual acuity outcome after indocyanine green angiography-guided laser photocoagulation of choroidal neovascularization associated with pigment epithelial detachment in eyes with age-related macular degeneration. METHODS: We retrospectively reviewed pretreatment and posttreatment visual acuity after laser photocoagulation to well-demarcated hyperfluorescent areas seen with indocyanine green angiography adjacent to or within pigment epithelial detachments in 20 eyes of 20 patients with age-related macular degeneration and suspected choroidal neovascularization. RESULTS: Visual acuity before and after laser photocoagulation was followed up for 3 to 24 months (median, 9 months). At 3 months after laser photocoagulation, visual acuity had improved 2 or more Snellen lines in two eyes (10%), worsened by 2 or more lines in 10 (50%), and remained unchanged in eight of 20 (40%). By 6 months after laser photocoagulation, visual acuity had improved by 2 or more lines in two eyes (12%), worsened by 2 or more lines in nine (53%), and remained unchanged in six of 17 (35%). At 9 months after laser photocoagulation, visual acuity had improved by 2 or more lines in one eye (9%), worsened by 2 or more lines in nine (82%), and remained unchanged in one of 11 (9%). CONCLUSIONS: Indocyanine green angiography-guided laser photocoagulation may temporarily stabilize visual acuity in some eyes with choroidal neovascularization associated with pigment epithelial detachments, but final visual acuity decreases with time.
