Subretinal neovascular membranes associated with choroidal nonperfusion and retinal ischemia.

This is the first well-documented case of co-existent underlying choroidal nonperfusion in an eye with a subretinal neovascular membrane that was subsequently treated with krypton red laser photocoagulation by the senior author (LEM). The possible role of chronic macular ischemia secondary to choroidal circulatory impairment is discussed in relationship to other well-established risk factors. Perhaps treatment to improve macular oxygenation would be a reasonable alternative to eradication of the neovascularization by direct laser photocoagulation.
