A macular hole can develop in your macula, the central part of your retina devoted to your central vision. This usually occurs spontaneously, though sometimes can occur after significant trauma. The macular hole can cause painless loss of central vision. Patients usually complain of a blurry circle in their central vision or severe distortion. Macular holes can be fixed with a vitrectomy, a surgery that is performed by a retina specialist in the operating room. During the surgery, a gas bubble will be injected into the eye. After the surgery, you will have to maintain a face down position for approximately 1 week. This includes sleeping on your stomach. This surgery can lead to a gradual improvement in central vision.
