The fovea contains the densest concentration of cone cells in this structure.
Mutations in FZD4, LRP5, or NDP can cause a genetic disease in which this structure shows exudates. Occlusion of its namesake vein creates a "blood and thunder" appearance. Atherosclerotic patients can have Hollenhorst plaques in the vessels found in this structure, which can cause amaurosis fugax. Ischemia (is-KEE-mi-a) in this structure shows up as cotton-wool spots. A lack of red reflex, or leukocoria, in children is indicative of a (*) tumor of this structure, caused by mutations in RB. The choroid provides oxygen to the outer layers of this structure, which contains glia called Mueller cells. In this structure, bipolar cells communicate with ganglion cells. The fovea contains the densest concentration of cone cells in this structure. For 10 points, name this thin layer of photoreceptors at the back of the eye.
