How is Retinal Detachment Caused?
Retinal detachment can occur as a result of:
A sagging vitreous (VIT-ree-us) — the gel-like material that fills the inside of your eye, Injury (Eye trauma), Advanced diabetes
- The retina is the layer of tissue that lines the inside of the eye. It is light sensitive and its function is to send visual signals to the brain, through the optic nerve.
- When we see, light goes through the optical system of the eye and hits the retina, like in a no digital camera.
- When the light hits the retina, this produces an image that is translated into neural impulses and sent to the brain through the optic nerve.
- In other words, an image focuses on the retina, nerve cells process the information, and they send it by electrical impulses through the optic nerve to the brain.
- If the retina is damaged, this can affect a person’s ability to see.
- Retinal detachment happens when this layer is pulled from its normal position. Sometimes, there are small tears in the retina. These, too, can cause the retina to become detached.
Who is at Risk Retinal Detachment?
The following factors increase your risk of retinal detachment:
- Retinal detachment is more common in people over age 50
- Previous retinal detachment in one eye
- A family history of retinal detachment
- Extreme near-sightedness (myopia)
- Previous eye surgery, such as cataract removal
- Previous severe eye injury
