Vitrectomy is a keyhole operation on the vitreous gel and retina at the back of the eye. It is used to treat problems such as retinal detachment, macular holes, and non-clearing vitreous haemorrhage.
How vitrectomy works
Under local or general anaesthetic, tiny instruments are passed through small ports in the white of the eye. The vitreous gel is removed and replaced with clear fluid or gas so that the surgeon can repair the retina or treat bleeding.
- Often combined with retinal laser or membrane peeling
- Gas or oil may be left in the eye to support the retina
- Careful positioning after surgery is sometimes required
