Choroidal neovascularization in fellow eyes of patients with advanced senile macular degeneration. Role of laser photocoagulation.
Choroidal neovascularization in fellow eyes of patients with advanced disciform macular scars usually has an unfavorable prognosis. Fifty-two such fellow eyes were treated, using the monochromatic green argon laser. The neovascular membranes were foveal in 24 eyes, juxtafoveal in ten eyes, and perifoveal in 18 eyes. Complete closure of the choroidal new vessels after treatment was seen in 46 eyes. Only one eye in the foveal group and five eyes in the juxtafoveal group had residual new vessels. After an average follow-up period of 16 months, improvement or stabilization of vision was seen in 36 eyes--18 eyes in the foveal group, four in the juxtafoveal group, and 14 in the perifoveal group. In view of the rewarding anatomical and functional results, photocoagulation, using the monochromatic green argon laser, should be considered in these high-risk eyes. Treatment of foveal neovascular membranes seems to be indicated if the visual acuity is 20/70 or worse.
