01
Overview
Photoreceptor support via retinal pigment epithelium (RPE) restoration is a therapeutic strategy aimed at preserving or restoring vision in degenerative retinal diseases by replacing or repairing dysfunctional RPE cells. The RPE provides critical support functions for photoreceptors, including visual pigment recycling, phagocytosis of shed outer segments, metabolic support, and maintenance of the blood-retina barrier. RPE restoration strategies involve transplantation of healthy RPE cells or sheets derived from various sources to re-establish photoreceptor support and prevent further vision loss.
