Clinical Profile, Visual Outcome and quality of Life in patients undergoing Pan retinal photocoagulation for Proliferative diabetic Retinopathy

Diabetesmellitus (D.M.) is a major medical problem throughout the world. The prevalence of diabetes in India is 2.4% in the rural population and 4.0-11.6% in the urban population. It is estimated that 20% of the currentglobal diabetic population resides in the Southeast Asia region.Worldwide 150 millioncases are currentlydiagnosed, predicted to bedoubled by 2025. India is committed to an initiative of Vision 2020: The Right to Sight, thus having targetsfor ophthalmic infrastructure in its tenth five-year plan. Diabetes mellitus (D.M.) is a significant cause of avoidable blindness in both developing and developed countries.Patients with diabetic retinopathy (DR) are 25 times more likely to becomeblind than non-diabetics. In thenatural course, approximately 50% of patients with very severe N.P.D.R. (non-proliferative diabeticretinopathy) progress to PDR (proliferative diabetic retinopathy) within1 year. Panretinal photocoagulation (P.R.P.) is the preferred form oftreatment for proliferative diabetic retinopathy (P.D.R.). The DRSfound that PRP (pan retinal photocoagulation) prevented severe visual loss by over 50% at 2 and 4 years of followup. However,many studies have been done on pan-retinal photocoagulation for proliferative diabetic retinopathy. The aim of this study is to observe the clinicalprofile, visual outcome and quality of life in patients undergoing pan-retinal photocoagulation for proliferative diabetic retinopathy.
