Abstract
A novel method of treating ischemic retinopathy is disclosed. After diagnosis of ischemic retinopathy, as for example as a result of retinal infarction, the ocular globe is penetrated with two small cannulae. An inflow and outflow perfusion is then established with an oxygenated perfluorochemical emulsion or other physiologically compatible oxygenated liquid. A sufficient perfusion rate is established and maintained to provide the metabolic needs of the retina for the 3 to 5 day period necessary to permit the natural healing process to occur. The method comprises removing at least a portion of vitreous body to create an intraocular perfusion space and establishing a perfusion of physiologically compatible oxygenated fluid through that perfusion space at a rate and for a duration sufficient to permit the natural healing process to occur. Alternatively, a method of diagnosing the condition of retinal tissue suspected of being ischemic is disclosed.
