Quick Summary

The retinal pigment epithelium (RPE) is the outermost layer of the retina, situated next to the choroid. It plays a crucial role in supporting the retina's function by absorbing stray light and preventing scattering, which is essential for clear vision. The RPE also contains light-sensitive molecules that convert light into chemical energy, initiating nerve impulses transmitted to the brain via the optic nerve. This layer is vital for the visual cycle, including the regeneration of rhodopsin, a pigment crucial for vision in dim light.123

detached retina
…supporting cells known as the retinal pigment epithelium. Most commonly, retinal detachments are caused by the passage of fluid through a break, or tear, in the retina, a situation called rhegmatogenous retinal detachment. The fluid is derived from the aging vitreous gel that fills the central eyeball space. The retinal…
