Layers of the retina

Download

The retina consists of 10 anatomically and physiologically distinct layers. The outermost layer is the retinal pigment epithelium, and the innermost is the nerve fiber layer, which is made of the axons of the ganglion cells. The outer layers in the retina derive their oxygen by diffusion from the vascular choroid, and the inner layers are nourished by capillaries derived from the branches of the central retinal artery.
