title: Laser photocoagulation of choroidal neovascularization in pathologic myopia: long-term results.
abstract: Direct laser photocoagulation of macular choroidal neovascularization (CNV) in pathologic myopia is still controversial. However, previous studies have reported encouraging results. One-hundred and thirty-three consecutively treated eyes were followed, in a prospective manner, for at least 12 months (108 of these were followed for 24 months, 84 for 36 months, 63 for 48 months, and 47 for 60 months) to evaluate the potential benefits and complications of laser treatment of extra-foveal macular CNV in pathologically myopic eyes. Pre-treatment mean visual acuity was 0.36. Post-treatment mean visual acuity was 0.33 at 1-year examination, 0.31 at 2 years, 0.32 at 3 years, 0.34 at 4 years, and 0.33 at 5 years. During the total follow-up period mean visual acuity did not change. Neovascular recurrences occurred in 58% of treated eyes by the end of the five-year follow-up. At final examination, complete destruction of CNV was achieved in 100 eyes (75%). These findings suggest that laser photocoagulation of macular choroidal neovascularization in pathologic myopia may be effective in preventing or limiting severe and irreversible loss of vision.
