Retinal arteriovenous anastomoses in the Vogt-Koyanagi-Harada syndrome.

A 15-year-old black girl had acute bilateral uveitis and other features of the Vogt-Koyanagi-Harada syndrome. Several months after the onset of her illness, she developed acquired retinal arteriovenous anastomoses in both eyes. By using fluorescein angiography, we documented that the anastomoses were collateral vessels developing in areas of damaged retinal pigment epithelium and retinal capillaries.
