Glaucoma is the second leading cause of blindness affecting about 67 million people worldwide. It is a progressive optic neuropathy. One of many risk factors is diabetes mellitus (DM). Diabetes retinopathy (DR) is one of the leading causes of blindness in the world. Retinal nerve fibre layer (RNFL) is an important structure which is often affected in the early pathogenesis of various ocular diseases. Evaluation of the RNFL thickness (RNFLT) is very useful for assessing optic nerve health. Optical coherence tomography (OCT) is a non-invasive technique used for RNFL analysis. A total of 60 patients (30 having POAG and 30 having POAG with type 2 DM) of either sex and age of 30-70 years were enrolled in this cross sectional study. All patients had open angles with BCVA of 20/40 or better. RNFLT was measured using spectral domain OCT. It was concluded that patients having POAG with T2DM had statistically significant RNFL damage i.e. reduced RNFLT, as compared to POAG without DM.
