retinal detachment
separation of the inner nervous layer of the RETINA from the outer pigmented layer (retinal pigment epithelium) to which it is attached. It commonly occurs when one or more holes in the retina allow fluid from the vitreous cavity of the eyeball to accumulate under the retina. Vision is lost in the affected part of the retina. The condition can be treated surgically by creating patches of scar tissue between the retina and the choroid by application of extreme cold ( see CRYOSURGERY ) or heat (see PHOTOCOAGULATION ); this, combined with PLOMBAGE , allows reattachment of the retina.
The retina is a layer of tissue in the back of your eye that senses light and sends images to your brain. It provides the sharp, central vision needed for reading, driving, and seeing fine detail. A retinal detachment lifts or pulls the retina from its normal position. It can occur at any age, but it is more common in people over age 40. It affects men more than women and whites more than African Americans. A retinal detachment is also more likely to occur in people who:
- Are extremely nearsighted
- Have had a retinal detachment in the other eye
- Have a family history of retinal detachment
- Have had cataract surgery
- Have other eye diseases or disorders
- Have had an eye injury
Symptoms include an increase in the number of floaters, which are little "cobwebs" or specks that float about in your field of vision, and/or light flashes in the eye. It may also seem like there is a "curtain" over your field of vision.
A retinal detachment is a medical emergency. If not promptly treated, it can cause permanent vision loss. If you have any symptoms, see an eye care professional immediately. Treatment includes different types of surgery.
