[Therapy of parapapillary subretinal neovascularization]

A large variety of diseases may cause a subretinal neovascularization originating from choroidal vessels. Four cases of parapillary choroidal neovascularisation are described, including neovascularization caused by senile and myopic degeneration, by drusen of the optic nerve head, and by angioid streaks. Obliteration of the neovascular membrane with confluent argon laser coagulation reduced metamorphopsia and prevented a progredient loss of visual acuity in all four patients.
