A retinal tear or a detached retina is repaired with a surgical procedure. Based on your specific condition, your ophthalmologist will discuss the type of procedure recommended, as well as the various risks and benefits of the treatment options.
Most retinal tears need to be treated by sealing the retina to the back wall of the eye with laser surgery or cryotherapy (a freezing treatment). Both of these procedures create a scar that helps seal the retina to the back of the eye. This prevents fluid from traveling through the tear and under the retina, which usually prevents the retina from detaching. These treatments cause little or no discomfort and may be performed in an ophthalmologist’s office.
Almost all patients with retinal detachments must have surgery to place the retina back in its proper position. Otherwise, the retina will lose the ability to function, possibly permanently, and blindness can result. The method for fixing retinal detachment depends on the characteristics of the detachment.
- Scleral buckle: This treatment involves placing a flexible band (scleral buckle) around the eye to counteract the force pulling the retina out of place. The ophthalmologist often drains the fluid under the detached retina, allowing the retina to settle back into its normal position against the back wall of the eye. This procedure is performed in an operating room.
- Pneumatic retinopexy: In this procedure, a gas bubble is injected into the vitreous space inside the eye in combination with laser surgery or cryotherapy. The gas bubble pushes the retinal tear into place against the back wall of the eye. Sometimes this procedure can be done in the ophthalmologist’s office. Your ophthalmologist will ask you to constantly maintain a certain head position for several days. The gas bubble will gradually disappear.
- Vitrectomy: This surgery is commonly used to fix a retinal detachment and is performed in an operating room. The vitreous gel, which is pulling on the retina, is removed from the eye and usually replaced with a gas bubble.
After successful surgery for retinal detachment, vision may take many months to improve and, in some cases, may never return fully. Unfortunately, some patients do not recover any vision. The more severe the detachment, the less vision may return. For this reason, it is very important to see your ophthalmologist regularly or at the first sign of any trouble with your vision.
