Vitreomacular Traction

Vitreomacular traction (VMT) does not always require treatment. In many cases, VMT is mild, or gets better on its own, as the vitreous completes its separation from the macula. However, in some cases, if the VMT is severe with significant symptoms, causes a macular hole, or does not get better on its own, then surgery may be required.

Surgery for VMT usually involves a vitrectomy, a form of "keyhole" surgery that uses small instruments to enter inside the eye to remove the vitreous gel. In some cases, a gas bubble is injected into the eye at the end of surgery, to replace the vitreous and prevent it from pulling on the retina gel.

VMT can be successfully relieved with surgery in the large majority of cases. Surgery helps to stabilise and prevent deterioration of vision, and in most cases also improves symptoms of blurred vision and distortion. The success of improving the vision varies from person to person and ranges from 60% to 80%. Some distortion may persist, depending on how long the symptoms and VMT have been there for, prior to surgery.
