Vitrectomy is a surgery to remove the vitreous gel from the middle of the eye camera.gif. It may be done when there is a retinal detachment or if blood in the vitreous gel (vitreous haemorrhage) does not clear on its own. Removing the vitreous gel gives your eye doctor better access to the back of the eye. Vitrectomy is done by an eye doctor (ophthalmologist) who has special training in treating problems of the retina.
During surgery, the doctor uses small tools to remove the vitreous gel. Then the doctor may treat other eye problems, such as a retinal detachment, vitreous haemorrhage, scar tissue on the retina, or tears or holes in the macula.
At the end of the surgery, the doctor may inject an oil or gas bubble into the eye. This lightly presses the retina against the wall of the eye. If an oil bubble is used, the doctor will need to remove the oil after the eye has healed.
