The surgery to repair a macular hole is unique because a gas bubble placed in the eye must remain in contact with the macula following surgery in order for the macular hole to remain pressed against the eyewall. ![]() What's unique about macular hole surgery? Once the gel is removed, the eye is filled with a special gas bubble which helps to flatten the edges of the macular hole against the eyewall to allow it to grow back together. This helps to relieve any traction caused by the gel pulling away from the retinal surface that tugs on the macula. In this surgery, tiny instruments are used to remove the gel which fills the inside of the eye. Treatment of a macular hole requires a surgery called a vitrectomy. The diagnosis of a macular hole requires a dilated eye exam with close inspection of the retina plus an imaging test called an OCT (ocular coherence tomography) that uses light waves to take cross-sectional pictures of the retina. This can take the form of blurred vision, distorted vision (where straight lines will appear wavy), or a growing dark spot in the central visual field. ![]() The most common symptom of a macular hole is a gradual decline in central vision.
