Assessment of Retinal Nerve Fibre Layer Thickness in Type 2 Diabetes Mellitus Patients Using Optical Coherence Tomography

Diabetes mellitus (DM) is chronic metabolic disorder which is globally prevalent and fast growing disorder, commonly leads to complications like neuropathy, nephropathy, retinopathy, keratopathy, cardiovascular diseases, and diabetic foot. Hyperglycemia affects both cornea and retina. As many studies have been conducted on OCT and it usefulness in Diagnosing Early Changes of Diabetic Retionpathy. This study aimed to do analysis of RNFL thickness in Type such that it leads to early diagnosis and treatment for the same. Method: The study was conducted on 200 patients which were equally divided into Group I consisting of 100 diabetic patients and Group II consisting of 100 nondiabetic patients in Department of Ophthalmology, Rama Medical College, Hospital and Research Centre, Hapur. In all study patients RNFL thickness using Nidek Retina Scan Duo RS -330 (SD -OCT) was recorded. Conclusion:The results of this study revealed significant alterations in RNFL thickness, as measured by OCT, in diabetic patients compared to nondiabetic controls.These changes are likely associated with earlystage neuronal and vascular abnormalities in the diabetic retina.
