Vitreomacular traction (VMT) is caused by an abnormal posterior vitreous detachment (PVD).  The vitreous gel lies inside the eye and provides support for the eye to develop properly. As we age, the vitreous gel naturally weakens and breaks down.

At some point in life, a PVD will occur when the vitreous gel collapses away and separates from the retina. In VMT there is an abnormally strong attachment between the macula (part of the retina responsible for central vision) and the vitreous. This stops the separation and instead causes pulling on and distortion of the macula.


What are the symptoms of VMT?

Some patients may not have any symptoms, while others may notice a blurring or distortion of their central vision.

How do you treat VMT?

Many patients do not require treatment if their vision is not being affected by VMT. However, there is a small risk of a macular hole developing and some may want the reassurance of monitoring the condition with regular ophthalmic examinations.

A vitrectomy treatment is recommended if the visual symptoms are affecting quality of vision.
