Retinal damage can cause sudden flashes of light, floaters, blurred or distorted vision, or a curtain-like shadow in your field of view. These symptoms require prompt evaluation by an eye specialist to prevent permanent vision loss.
The retina is a thin, delicate layer at the back of the eye that plays a key role in vision. It converts light into signals sent to the brain. When the retina becomes damaged, vision can change suddenly or gradually. Knowing the warning signs early can help protect your eyesight.
What Is Retinal Damage?
Retinal damage occurs when the retina’s structure or blood supply is affected, often requiring evaluation by the Best Retina Eye Specialist in Dubai. This damage can disrupt how visual signals are sent to the brain. If left untreated, retinal damage may lead to partial or complete vision loss.

How the Retina Works
The retina contains specialized cells called rods and cones.
Rods help with vision in low light
Cones allow colour and detailed vision
The macula, located at the centre of the retina, is responsible for sharp central vision. Damage to any part of the retina can interfere with how visual information reaches the brain.
