Retinal Biology

Retinal biology focuses on the retina, a thin layer of tissue at the back of the eye that captures light and converts it into electrical signals. These signals are sent to the brain via the optic nerve, allowing us to see. The retina contains specialized cells called photoreceptors—rods, which help us see in low light, and cones, which detect color and detail. Proper retinal function is essential for clear vision. Understanding retinal biology helps in diagnosing, treating, and preventing eye diseases like macular degeneration and diabetic retinopathy.
