Diabetic Retinopathy is an eye disease caused by complications of diabetes.
Diabetes causes damage to the small blood vessels that nourish the retina. These blood vessels may expand and leak fluid. Fluid that leaks at the macula (central retina) can cause macular oedema which may cause reduced visual acuity. Some blood vessels may become closed and abnormal new blood vessels may grow, which can leak and cause vitreous haemorrhage.
Treatment for this eye disease involves laser to the retina, injections of intravitreal steroids and vitrectomy. Ultimately, better glycaemic control is required to prevent vision loss from diabetes.
