Rhegmatogenous retinal detachment is the most common type of retinal detachment. It can happen if you have a small tear or break in your retina. When your retina has a tear or break, the gel-like fluid in the center of your eye called vitreous can get behind your retina. The vitreous then pushes your retina away from the back of your eye, causing it to detach. Aging is the most common cause of rhegmatogenous retinal detachment.
As you get older, the vitreous in your eye may change in texture and may shrink. Sometimes, as it shrinks, the vitreous can pull on your retina and tear it. Other things that can increase your risk of rhegmatogenous retinal detachment are eye injuries, eye surgery, and nearsightedness. Tractional retinal detachment happens if scar tissue on your retina pulls your retina away from the back of your eye.

What is glaucoma? You can expect some discomfort after surgery for a detached retina. Your ophthalmologist will prescribe any necessary medications for you and advise you when to resume normal activity. You will need to wear an eye patch for a short time. If a gas bubble was placed in the eye, your ophthalmologist may recommend that you keep your head in special positions for a time.
If a gas bubble is used, you will be restricted from air travel, scuba diving, and certain types of anesthesia until after the bubble is gone. A change of glasses may be necessary after the retina has been reattached.
Any surgery has risks; however, an untreated retinal detachment will usually result in permanent severe vision loss or blindness. Some of these surgical risks include infection, bleeding, high pressure inside the eye, or cataract.
Most retinal detachment surgery is successful, although a second operation is sometimes needed. If the retina cannot be reattached, the eye will continue to lose sight and ultimately become blind. Vision may take many months to improve and in some cases may never fully return. Unfortunately, some patients, particularly those with chronic retinal detachment, do not recover any vision. The more severe the detachment, and the longer it has been present, the less vision may be expected to return.
For this reason, it is very important to see your ophthalmologist at the first sign of trouble. Reviewed by Grant M. Comer, M. Updated visitor guidelines. Detached Retina Retinal Detachment.
