A 40-year-old women with a 17-year-history of glaucomatocyclitic crises in 1 eye developed idiopathic foveal subretinal neovascularization in the other eye. The subretinal neovascular membrane spontaneously regressed over a 2-month period, and useful reading vision was subsequently maintained for more than 6 years. This favorable outcome is discussed in relation to the previously reported cases of idiopathic macular subretinal neovascularization.
