Loss of vision caused by apoptotic cell death is a feature ofage-related macular degeneration, retinitis pigmentosa, glaucoma,and other degenerative retinal diseases. Degeneration of photoreceptors cells that transduce the light is involved inmacular degeneration and retinitis pigmentosa, whereas lossof retinal ganglion cells, the output neurons of the retinathat project through the optic nerve, results in glaucoma.
It has long been known that exposure to intense light causesthe degeneration and death of photoreceptors. Recently, Grimmet al.1 used mouse models of photochemical retinal injury todecipher the process of apoptosis in photoreceptor cells. They. . . [Full Text of this Article]
