Study Notes
Retina Layers
- The pigmented epithelium layer is responsible for absorbing stray light and preventing back-reflection.
- The pigmented epithelium also recycles photoreceptor components.
Retina Layers and Function
- The nerve fiber layer contains axons that travel through the optic nerve.
Light Path Through Retina Layers
- Light must travel through one layer (pigmented epithelium) before reaching the photoreceptor layer.
Retina Layers and Eyeball Structure
- The pigmented epithelium layer is the closest to the outside (sclera) of the eyeball.
