What is it?
Vitrectomy is a microsurgical operation in which the vitreous gel inside the eye is removed with fine instruments inserted through very small openings in the white of the eye. It allows the surgeon to work directly on the retina.
Why it may be recommended
Vitrectomy may be recommended for retinal detachment, macular hole, epiretinal membrane, vitreous haemorrhage that does not clear, complications of diabetic retinopathy, intraocular foreign bodies and some infections or inflammations inside the eye.
How it is performed
The operation is usually performed under local anaesthesia, sometimes with sedation, or under general anaesthesia. After the vitreous is removed, further steps may include peeling membranes, laser treatment, and filling the eye with fluid, gas or silicone oil to support the retina.
Preparation
Before surgery, your general health, current medicines (especially blood thinners) and eye findings are reviewed. You receive instructions about eating, drinking and eye drops before the procedure.
Recovery
Vision is often blurred at first and improves gradually. If gas is used, head positioning may be needed, and flying or travelling to high altitude must be avoided until the gas has been absorbed. Silicone oil may need a second operation to remove it.
Possible risks
Possible risks include cataract formation or progression, raised eye pressure, bleeding, infection inside the eye (endophthalmitis), retinal tears or detachment, and the need for further surgery. Your surgeon discusses the risks that apply to your eye.
Follow-up
Follow-up visits in the days and weeks after surgery check healing, eye pressure and the position of the retina.
