Weakening of the orbital septum and herniation of the orbital fat adds to the bulging appearance. The upper and lower eyelids use skin, muscles, glands, nerves and other tissues to keep the eyes mobile, moist and lubricated.

Comparison of event-based analysis of glaucoma progression assessed subjectively on visual fields and retinal nerve fibre layer attenuation measured by optical coherence tomography. In dry AMD, light-sensitive cells slowly break down in the macula, resulting in gradual vision loss. These defects originate from damage to the arcuate nerve fiber bundlesoften visible on funduscopy with retinal nerve fiber layer (RNFL) wedge defects or neuroretinal rim notching.
