The vitreous may be replaced with a clear fluid. During the surgery, very small openings are made in the eye wall, and most of the vitreous (the gel-like fluid that fills the eye) is removed.Īfter that, the surgeon may inject an air or gas bubble into the eye to hold the retina in place and may use a laser or freeze the retina to reattach or repair it. Numbing drops, shots, or general anesthesia are used to make sure there is no pain during the procedure. Vitrectomy A vitrectomy is similar to a pneumatic retinopexy, but the surgery is more involved and is usually performed in a hospital rather than a doctor’s office. If the central retina was detached prior to surgery, vision often improves after a successful reattachment, but some degree of permanent vision loss can occur. In cases when the center of the retina was not detached prior to surgery, postsurgery vision tends to be about the same as preoperative vision. The macula is where you do all your fine seeing - it’s necessary for driving, reading, and seeing fine detail,” says VanderBeek. “In the central part of your retina, there’s an area called the macula. Retinal detachment repairs are successful in 9 out 10 cases, though sometimes more than one procedure is necessary to successfully reattach the retina. With prompt diagnosis and treatment, the prognosis can be good for retinal detachment. An OCT is a noninvasive test that uses light waves to take cross-section pictures of the retina so that each layer is visible. If the eye doctor isn’t able to make a diagnosis from the dilated eye exam, an ultrasound or optical coherence tomography (OCT) scan of the eye may be performed to see the exact position of the retina.
