Abstract
INTROUCTION: Diabetes mellitus belongs to a type of metabolic disease characterised by hyperglycemia resulting from • Defects in insulin secretion • Reduction in the effectiveness of secreted insulin • Combination of the above The raised blood sugar levels thus produces the characteristic symptoms of • polyuria • polydipsia • polyphagia . AIM OF THE STUDY: The aim of my study was to find the incidence of retinopathy changes, in newly detected DM type II. 200 eyes of 100 patients attending the ophthalmology outpatient department of the Stanley Medical College, Hospital, Chennai between the period from July 2010 to November 2012 were studied. DISCUSSION: The aim of our study was to find the incidence of retinopathy changes, in newly detected DM type II. 200 eyes of 100 patients attending the ophthalmology outpatient department of the Stanley Medical College, Hospital, Chennai were studied. Our observation were compared with various other studies about diabetic retinopathy. Various studies performed in India as found that there is an increased prevalence of DR in type II DM in the past 30 yrs DR prevalence in newly diagnosed subjects in my study is16% But it is comparatively lower than the prevalence data found in Europe study which is 20% to 35% SUMMARY: 200 eyes of 100 patients were studied during the period from July 2010 to November 2012. The predominantly affected group were between 40 to 50 years of age(42.5%). The male:female ratio was 2.1:1. A majority of patients had visual acuity between 6/9 and 6/18 on first presentation(43.5%). Of them 12% of patients had positive family history. 33% of the patients were exposed to risk factors like smoking, alcohol and anaemia. 12% 0f the patients had bilateral diabetic retinopathy. Of the 200 eyes evaluated 62 eyes had NPDR and 2 had PDR while 336 had no features of diabetic retinopathy. Among the NPDR majority (38 eyes) fell under moderate NPDR . Of the 100 patients 1 had VH at the time of persentation 3% of the patients had POAG during the initial presentation. Levels of glycosylated hemoglobin level (HbA1c) were more than 7mmol/l in patients with DR when compared to patients without DR. This indicates patients would have had unnoticed DM for a longer duration. CONCLUSION: Incidence of DR is common among middle aged working population. Both eyes were usually affected ,though asymmetrically. Detailed fundus examination and FFA in selected cases are important in diagnosing the type and severity of diabetic retinopathy. In conclusion DR associated with vision threatening complications can be made out even at the time of diagnosis of diabetes mellitus type II. So regular ophthalmological evaluation is necessary to detect fundus changes in early stages in new cases of DM type-2. Early diagnosis and treatment of DR helps to stabilize the visual acuity and prevent further loss. Diagnosis of complications of DR at the earliest helps to control progression of PDR. Increased awareness of the ophthalmological complication in diabetes is necessary in the society to prevent unnecessary visual morbidity in diabetic patients.
