The retina, a thin layer of tissue located at the back of the eye, plays a vital role in capturing light and sending visual signals to the brain. Retina diseases, which affect this crucial component of vision, can lead to severe vision impairment or even blindness if left untreated. Understanding these conditions is key to early diagnosis and effective treatment
The retina consists of light-sensitive cells (rods and cones) and nerve cells that transmit signals to the brain. Rods are responsible for vision in low light, while cones enable color perception and sharp central vision. The macula, a small central area of the retina, is critical for detailed vision, such as reading or recognizing faces.

Typically, it’s minimally painful with local anesthesia.
High blood sugar damages retinal vessels, leading to diabetic retinopathy.
A diet high in antioxidants, regular exercise, and avoiding smoking.
Yes, especially genetic conditions like retinitis pigmentosa.
