Macular hole is the formation of a round gap at the centre of the macula. This leads to blurring of vision and distortion of images. A blind spot may appear at the middle of vision.

Macular hole 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 is injected to keep the hole dry and allow it to heal. It is helpful to look down for 3 to 5 days to keep the macular hole above fluid. You must not travel by air while gas bubble remains.
Vitreous is removed through tiny cuts on 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 hole.
