Retinal degeneration refers to a group of eye disorders that result in the progressive loss or damage to the retina, which is responsible for detecting light and converting it into electrical signals that are sent to the brain via the optic nerve. This condition can lead to vision impairment or blindness if not treated properly. There are several types of retinal degeneration including age-related macular degeneration (AMD), retinitis pigmentosa, and glaucoma. The exact cause of these disorders varies but they often involve the breakdown or death of retinal cells leading to a loss of vision.
