Pathophysiology: Diabetic retinopathy is a common complication of diabetes. It occurs when high blood sugar levels damage the cells at the back of the eye (known as the retina). If it isn't treated, it can cause blindness.
Symptoms: Symptoms may only become noticeable once the disease advances, but the typical symptoms of retinopathy to look out for include: Sudden changes in vision / blurred vision, Eye floaters and spots, Double vision, Eye pain.
Treatment: There is no cure for diabetic retinopathy. But laser treatment (photocoagulation) is usually very effective at preventing vision loss if it is done before the retina has been severely damaged. Surgical removal of the vitreous gel (vitrectomy) may also help improve vision if the retina has not been severely damaged.
Major Research: Vasotide eye drops successfully treat retinal diseases, could treat diabetic retinopathy in the future. A plant-based diet can reverse diabetic retinopathy
