What is a vitrectomy?

A vitrectomy is a type of surgery that treats disorders of the retina and the vitreous. The retina is the light sensitive portion of the eye that images we see get focused on; it lines the inner portion of the eye. The vitreous is the jelly-like liquid that surrounds the retina and fills most of the eye. In a vitrectomy surgery, the vitreous is removed and often replaced with a saltwater solution.

How does a vitrectomy improve my vision?

Vision can be poor if the retina is not in its normal position or if light is obscured before reaching the retina. A vitrectomy removes any scar tissue that displaces or tears the retina. It also removes any blood or debris that may be blocking or blurring light as it focuses on the retina.

When is a vitrectomy necessary?

Vitrectomy surgery is often done to patients with diabetic retinopathy. People with this condition commonly have bleeding and scar tissue in the vitreous and on the retina. Other eye problems that may require vitrectomy surgery are the following: retinal detachment, severe eye injury, infection inside the eye, a macular hole and wrinkling of the retina.
