The retina is a thin layer of tissue located at the back of the eye that contains light-sensitive cells called photoreceptors. These cells capture light and send signals to the brain, allowing us to see images. Research in the field of retina focuses on understanding the structure and function of these cells, as well as investigating diseases and disorders that affect the retina, such as age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa. Researchers are also exploring potential treatments and therapies to preserve and restore vision in individuals with retinal diseases.
