Novel Trends in Screening for Diabetic Retinopathy

Le résumé fourni par la source

Diabetic retinopathy is a major cause of ocular morbidity all around the world.With increasing the duration of disease, retinopathy also worsens.Currently more than 250 million people worldwide are suffering from Diabetes.Out of them, more than 150 million are having retinopathy.WHO projects that the number of people affected will be doubled by 2025 [1].Screening for DR is important because the majority of patients who develop DR have no symptoms until macular edema (ME) and/or proliferative diabetic retinopathy (PDR) are already present.The efficacy of laser photocoagulation and/or vascular endothelial growth factor (VEGF) inhibitors in preventing visual loss from PDR and ME is well established in randomized trials.However, these therapies are more beneficial in preventing visual loss than reversing diminished visual acuity.Thus, early detection through screening programs and appropriate referral for therapy are important to preserve vision in individuals with diabetes [2].
