Ocular masquerade syndrome was diagnosted in two patients with chronic uveitis. The patients presented non-Hodgkin's lymphoma as the final diagnosis two forms of intraocular retinal pigment epithelium involvement was seen. One case was flecks of the retinal pigment epithelium and another case was a solid retinal pigment epithelium detachment. These unusual presentations of non-Hodgkin's lymphom...

PURPOSE Pigment epithelium derived factor (PEDF) is a secreted protein with demonstrated anti-angiogenic properties, and with potential application for the treatment of neovascular disease. Delivery of pigment epithelium derived factor to the retina via virus mediated gene transfer has been shown to inhibit neovascularization in a number of experimental models. While pigment epithelium derived ...

Integrity of retinal pigment epithelial cells is necessary for photoreceptor survival and vision. The essential omega-3 fatty acid, docosahexaenoic acid, attains its highest concentration in the human body in photoreceptors and is assumed to be a target for lipid peroxidation during cell damage. We have previously shown, in contrast, that docosahexaenoic acid is also the precursor of neuroprote...

Organ culture of human choroid and retinal pigment epithelium was maintained in medium RPMI 1640 with Millipore filter as support for various periods up to six weeks. The tissues were obtained from autopsy and surgical materials. The cultures were studied by light and electron microscopy. The tissues maintained by this culture method appeared to be in a relatively normal active state, without o...
