Improtance of Lifestyle Management to Prevent Diabetic Retinopathy
INTRODUCTION
DIABETES is the disease which occurs when the pancreas does not secrete insulin or the body is unable to process it properly. INSULIN is the hormone that monitors the level of the sugar in the blood.
DIABETIC EYE DISEASE refers to a group of eye problems that people with diabetes may face as a complication of diabetes that may cause severe vision loss or even blindness.
DIABETIC RETINOPATHY is the most common diabetic eye disease and a leading cause of blindness. It involves small haemorrhages from broken arteries in the retina, with yellow waxy discharge or retinal detachment. Sometimes abnormal new blood vessels grow on the surface of the retina. It actually affects the circulatory system of the retina.
ASSESSMENT:
Diabetic Retinopathy is one of the important micro vascular complications of the Diabetes. The following data are the chief point of concern to prepare an educational session on Diabetes Retinopathy. * Diabetic Retinopathy is responsible for 4.8 % of the 37 million cases of blindness due to eye diseases throughout the world. (1.8 million people). * The proportion of blindness due to Diabetic Retinopathy is 3 – 7 % in South East Asia and Western Pacific, 15 – 17% wealthier Western community. * About 8000 people each year is becoming blind due to Diabetic Retinopathy. * Both Type I and Type II Diabetes are vulnerable but in prolonged cases (more than 20 years), the occurrence is high. * According to the Research to Prevent Blindness, by NISE, NSF, 65000 diabetics develop Proliferative Retinopathy every year.
PATHOPHYSIOLOGY: Diabetes mellitus is a genetically influenced group of diseases that share glucose intolerance. It is characterized as a disorder of metabolic regulation as a result of deficient or malfunctioning insulin or cellular insulin receptors. Biochemistry involving the sorbitol formation and plays a role in the destruction of pericytes, which are cells that support the vascular
