The chances of recovering vision are greater when the retina is repaired before the macula is detached. Most people with retinal detachment need surgery to repair it, either immediately or after a short time. There are several types of surgery used depending on the severity and type of detachment. Patients with tears or small detachments can often be treated in the office with laser surgery, gas bubble injection, or a freeze treatment called cryopexy. Patients with more severe retinal detachment need to go to the operating room, where different types of surgery can be performed to reattach the retina. Once the retina is reattached, vision often improves or 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.
