RPE (Retinal Pigment Epithelium)

The retinal pigment epithelium (RPE) is a layer of pigmented cells located at the back of the eye, just beneath the retina. It plays a vital role in supporting the health and function of the retinal cells responsible for vision. The RPE nourishes retinal cells by transporting nutrients, removes waste products, absorbs excess light to improve visual clarity, and helps maintain the blood-retina barrier. It also aids in the visual cycle, essential for converting light into signals sent to the brain. Overall, the RPE is crucial for maintaining a healthy retina and ensuring clear, sharp vision.
