People with retinal detachment should seek emergency medical attention from an ophthalmologist. Chances of recovering function are greater when the retina is repaired before the macula is detached. Most people with retinal detachment will need surgery to repair it, either immediately or after a short period of time. There are several types of surgery used depending on the severity and type of detachment. Patients with severe cases will need to go to the operating room, although some cases of retinal detachment can be treated with an outpatient procedure. Small holes and tears can be treated with laser surgery or a freeze treatment called cryopexy. Once the retina is reattached, vision improves and stabilizes. A person's ability to read with the affected eye after surgery depends on whether the macula was detached, how long it was detached, the severity of the retinal detachment, and the type of treatment performed.
