Abstract

INTRODUCTION: With the increase in sedentary lifestyle the prevalence of diabetes mellitus has increased globally. It is one of the leading causes of blindness worldwide, with the rise in cases of diabetes its microvascular complications (diabetic retinopathy) have also increased. Optical coherence tomography (OCT) has been of great use in evaluating the ganglion cell complex. We conducted the study to compare the thickness of ganglion cell complex in diabetics and normal individual on OCT.

Methodology: 90 eyes of 90 patients were included in the study. 30 control, 30 diabetic with diabetic retinopathy changes and 30 diabetic with no diabetic retinopathy changes.

Result: This study showed that there is significant GCC thinning in diabetes which is mainly focal than diffuse and non-significant loss of RNFL. The GCC and RNFL loss in diabetics on Oct can be a useful non-invasive tool for early detection of neuronal loss even before retinopathy changes are seen.
