When is surgery the treatment for diabetic retinopathy?
If you have NPDR, your ophthalmologist may recommend laser treatment and/or injections in the eye.
If you have advanced Proliferative Diabetic Retinopathy, you may require surgery called vitrectomy.
Vitrectomy involves removing the vitreous gel, new abnormal vessels, scar tissues from the retinal surface and tractions. It aims to prevent future bleeds and retinal detachment. The surgery takes c. 1-2 hours and is done either under local or general anaesthetic. An injection is done in the eye a week before the surgery to reduce the risks of complications and bleed. The risks of surgery include loss of vision (rare), retinal detachment, cataract and the need for further surgery.
