What occurs in retinal detachment?

In retinal detachment, the critical event is the separation of the retina from its underlying layer of support tissue, known as the retinal pigment epithelium (RPE). This detachment disrupts the normal functioning of the retina, which is essential for visual processing. The retina contains light-sensitive cells that convert light into neural signals, ultimately allowing for vision. When the retina is pulled away from its normal position, it can lead to vision loss if not treated promptly.

This condition can occur due to a variety of reasons, such as a tear or hole in the retina, accumulation of fluid beneath the retina, or as a result of trauma. The implications of retinal detachment are serious, as it can result in permanent vision loss if not addressed through medical intervention, such as surgery or laser treatment.
