    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.
