Abstract
Two Hispanic patients with Vogt-Koyanagi-Harada (VKH) syndrome each developed a disciform lesion involving the macula of one eye several months after the onset of symptoms. Each had extraocular manifestations which included pleocytosis of the cerebrospinal fluid. The disciform lesions were associated with retinochoroidal anastomoses, a finding not previously reported in VKH syndrome. Each patient had a separate extramacular disciform lesion in the same eye. Two other Hispanic patients with diffuse bilateral intraocular inflammation had ocular findings consistent with VKH syndrome. One of these patients developed bilateral peripapillary disciform lesions and the other developed a disciform macular scar in one eye. Fluorescein angiography in each patient showed early irregular hyperfluorescence with late intense staining. The disciform detachments occurred in areas of reactive proliferation of the retinal pigment epithelium, and we postulate that growth of subretinal new vessels occurred through areas of Bruch's membrane that were damaged by the inflammation.
