The retina is a layer of tissue at the back of the eye that senses light and sends images to the brain, giving the sharp, central vision needed for reading, driving and fine detail. In a retinal detachment, the retina lifts or pulls away from its normal position.
Who is at risk
It can happen at any age, but is more common over 40, in men more than women, and in whites more than African Americans. It is also more likely in people who:
- are extremely nearsighted;
- have had a detachment in the other eye;
- have a family history of it;
- have had cataract surgery;
- have other eye diseases or disorders;
- have had an eye injury.
Warning signs
- a sudden increase in floaters — little "cobwebs" or specks drifting across your vision;
- flashes of light in the eye;
- a "curtain" over part of your field of vision.
What to do
A retinal detachment is a medical emergency: untreated, it can cause permanent vision loss. If you have any of these symptoms, see an eye care professional immediately. Treatment is by several kinds of surgery.
