Severe occlusive disease of the carotid artery may produce a rare syndrome of chronic ocular ischemia. Prolonged retinal hypoxia is associated with characteristic funduscopic changes and neovascularization of the iris, with subsequent obstruction of aqueous humor resorption. A case of neovascular glaucoma as a result of severe bilateral carotid occlusive disease and the pathophysiology involved are discussed. Definitive treatment consisted of carotid endarterectomy and aggressive control of intraocular pressure, including operative placement of a drainage implant in the anterior chamber of the eye. Seizure activity and an exacerbation of glaucoma developed after successful revascularization, exemplifying the derangements in cerebral and ocular function that may result from chronic hypoperfusion.
A choroidal metastasis from a primary breast carcinoma in a 32-year-old woman underwent clinically complete regression during a course of five-drug combined chemotherapy for widespread metastases. The need for radiation therapy to the eye was thus obviated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
