Study of Incidence of Macular Edema in Diabetic Retinopathy

Dr. Neeti R. Sheth | Dr. Tanvi M. Kamothi

Abstract: Study of Incidence of macular oedema in diabetic retinopathy. Purpose: With advent of optical coherence tomography (OCT), the presence and severity of DME can now be assessed accurately and to examine different diabetic retinopathy lesions (microaneurysms, haemorrhage, neovascularisation) to compare noncontact lens biomicroscopy with Optical Coherence Tomography (OCT) for detection of diabetic macular edema. Materials and Methods: This is a cross sectional study carried out on 1000 eyes of 500 patients of age group from 18-80 years, selected by nonprobability convenient sampling having no significant media opacity like dens cataract, significant corneal opacity, vitreous hemorrhage which prevents visualization of fundus. Detailed history taking, assessment of visual acuity (unaided, best corrected), detailed anterior and posterior segment examination including Central Macular Thickness (CMT) by Optical Coherence Tomography (OCT) was done in all the patients. Result: Clinically incidence of macular edema was 9.8 % and by OCT examination it was 12 %. Conclusion: Average macular thickness in PDR patients is higher than NPDR Patients. Higher the macular thickness, lesser the visual acuity. Incidence of macular oedema is higher according to OCT (12 %) than clinical findings (9.8 %).
