Vitrectomy

Vitrectomy is the surgical removal of thevitreous gel from the middle of theeye. It may be done when there is aretinal detachment, since removing the vitreous gel gives your eye doctor (ophthalmologist) better access to the back of the eye. The vitreous gel may also be removed if blood in the vitreous gel (vitreous hemorrhage) does not clear on its own.

During a vitrectomy, the surgeon inserts small instruments into the eye, cuts the vitreous gel, and suctions it out. After removing the vitreous gel, the surgeon may treat theretina with a laser (photocoagulation), cut or remove fibrous or scar tissue from the retina, flatten areas where the retina has become detached, or repair tears or holes in the retina ormacula.

At the end of the surgery, silicone oil or a gas is injected into the eye to replace the vitreous gel and restore normal pressure in the eye.

Vitrectomy is always done by an eye doctor who has special training in treating problems of the retina.
