The Retina

The Retina is an extremely crucial structure for vision. It is located in the posterior segment (back of our eye). In lay terms, it is called the curtain of the eye.
The retina can be divided into two regions: the central (macula) and the peripheral. The macula is a very small area in the center of the retina upon which light rays are focused by the cornea and the lens of the eye. The macula being the most sensitive portion of the retina is responsible for acute (sharp) vision, – that is for reading, writing, threading a needle and other fine tasks. The periphery of the retina gives us the vision to the side, which is called “peripheral vision”. This is what we refer to when we say, “I saw something from the corner of my eye.”

Common Retinal Disoders include-

DIABETIC RETINOPATHY
AGE RELATED MACULAR DEGENERATION
VASCULAR OCCLUSIONS
RETINAL DETACHMENT
