Subretinal and disc neovascularisation in serpiginous choroiditis.

Three out of 15 patients with serpiginous choroiditis who have been followed up for 1 to 10 years (mean 4.9 years) developed subretinal neovascularisation in the macula. In one eye new vessels were treated with argon laser without attaining permanent obliteration, in the second eye the neovascular membrane was regarded as untreatable because it was under the fovea, and in the third eye new vessels became obliterated spontaneously after atrophy of the surrounding choriocapillaris and the pigment epithelium of the retina. In a furth patient disc new vessels were seen at the active stage of serpiginous choroiditis; these new vessels disappeared after scarring of the initial chorioretinal lesions.
