Rubeosis iridis in "pseudogliomas"

Abstract

A total of 85 eyes (75 patients) with pseudogliomas (i.e., certain conditions which simulate retinoblastoma, were examined histopathologically to determine the incidence of rubeosis iridis. Neovascularization of the anterior surface of the iris was found in 70 eyes (82%). The principal associated changes in these eyes were moderate to severe inflammation of the uveal tract and retinal detachment. These findings are interpreted as indicating that inflammation, retinal detachment, and/or ischemia are effective stimulants in producing iris neovascularization, and rubeosis is not a significant factor in differentiating eyes with retinoblastoma from those eyes with pseudogliomas.
