Investigations
Procedures
Vitreomacular traction (VMT) develops when the vitreous gel separates from the retina but remains attached to the central macula.
VMT
VMT may resolve spontaneously. However, the constant pulling on the macula can cause blisters to form and eventually result in blurring and distortion of vision. When severe, VMT can lead to a full thickness macular hole, which will lead to legal blindness.

Symptomatic VMT is treated by vitrectomy surgery. The surgery is performed under local anaesthesia with minimal discomfort. With modern techniques, sutures are usually not required. A bubble of gas may be injected to help blisters heal. It is helpful to look down for 3 to 5 days to keep the macula above fluid and keep it dry. You must not travel by air while gas bubble remains.
Vitreous is removed through tiny cuts in the sclera (white of eye) using an automatic cutter.
A thin membrane on the surface of the macula is stained with a dye and peeled with forceps to release tension from the macula.
Gas bubble may be injected to keep the macula dry.
