What is a retinal detachment?
A retinal detachment occurs when the retina, a nerve layer at the back of the eye that senses light and sends images to your brain, is pulled away from its normal position. The retina does not work when it is detached.
A retinal detachment is a very serious problem that almost always causes blindness unless it is treated.
What causes a retinal detachment?
The vitreous is a clear gel that fills the middle of the eye. As we get older, the vitreous may pull away from its attachment to the retina at the back of the eye.
Usually the vitreous separates from the retina without causing problems. But, sometimes the vitreous pulls hard enough to tear the retina in one or more places. Fluid may pass through the retinal tear, lifting the retina off the back of the eye.
What are the warning signs of a retinal detachment?
The symptoms listed below, may indicate the presence of a retinal detachment:
These symptoms do not always mean a retinal detachment is present; however, you should see your eye doctor as soon as possible.
What treatment is needed?
Retinal Tears
Most retinal tears need to be treated with laser surgery or cryotherapy (freezing), which seals the retina to the back wall of the eye.
Retinal Detachments
Almost all patients with retinal detachments require surgery to put the retina back in its proper position. There are several ways to fix a retinal detachment. The decision of which type of surgery and anesthesia (local or general) to use depends upon the characteristics of your detachment.
