- Finally, the retina and retinal pigment epithelium differentiate from the optic cup, and the optic nerve develops from the optic stalk.
- The retina is composed of two layers, including the stratified inner sensory layer, which is closest to the vitreous, and a single outer layer of retinal pigment epithelium, which is attached to the choroid by Bruch's membrane.
- Some investigators believe that the disease resides in the neural retina (rods and cones), whereas others are studying the retinal pigment epithelium (the layer of cells that provide nutrition to the rods and cones).
