Retinal Detachment

What is Retinal Detachment?

  • Retinal detachment is a complicated eye problem caused by the separation of retina from its supporting layers.
  • The retina is a nervous tissue that transmits information we see to the brain.
  • When the retina is detached information cannot be relayed to the brain and you could permanently lose vision if the detached retina isn’t repaired promptly.

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

Treatment History

  • Previous retinal detachment in one eye

Family Background

  • A family history of retinal detachment


  • Extreme near-sightedness (myopia)

Cataract History

  • Previous eye surgery, such as cataract removal


  • Previous severe eye injury

Eye disease

  • Previous other eye disease or inflammation

What are the signs and symptoms of Retinal Detachment?

Retinal detachment itself is painless. But warning signs almost always appear before it occurs or has advanced, such as:

  • The sudden appearance of many floaters — tiny specks that seem to drift through your field of vision
  • Flashes of light in one or both eyes
  • Blurred vision
  • Gradually reduced side (peripheral) vision
  • A curtain-like shadow over your visual field

What kind of the treatment & benefit for Retinal Detachment?

Treatment goal is to repair the tear, hole or detachment. Various techniques are available depending on the severity of the detachment. Mainly:

  • Laser
  • Surgery

How to Prevent Retinal Detachment?

  • Understand the warning signs.
  • If you are highly short-sighted, have regular, dilated eye examinations.
  • If you have a family history of retinal detachment, have regular, dilated eye examinations.
  • Have a thorough eye examination if you have had serious eye injury.
  • Wear safety eye wear during sports or other hazardous activities.
