Vitrectomy is a surgical procedure used to remove the vitreous gel from the eye, which can become cloudy or pull away from the retina in certain retinal conditions like retinal detachment, diabetic retinopathy, or macular holes. During the procedure, the vitreous is removed to allow better access to the retina for treatment, and sometimes a gas bubble or silicone oil is used to help the retina heal and reattach.

Vitrectomy is performed under local or general anesthesia, depending on the complexity of the case. The procedure can significantly improve vision and help prevent further damage to the retina.

Vitrectomy is often necessary for patients with serious retinal diseases or trauma that cannot be treated with less invasive methods.
