Subretinal choroidal neovascularization in birdshot retinochoroidopathy.

We studied four eyes of two patients with bilateral birdshot retinochoroidopathy which developed subretinal choroidal neovascular membranes involving the macula. The subretinal choroidal neovascular membranes in our patients developed six months to five years after the onset of the disease. Both patients described decreasing visual acuities at the time when the choroidal neovascular membranes were identified. Adjacent to the classic depigmented areas of birdshot retinochoroidopathy were increased pigmentation, hemorrhage, or fluid indicative of subretinal neovascularization. Fluorescein angiography confirmed the presence and demonstrated the location of these membranes.
