PURPOSE: To obtain retinal nerve fibre layer thickness measurements by optical coherence tomography (OCT) in normal Indian population. MATERIALS AND METHODS: Total of 118 randomly selected eyes of 118 normal Indian subjects of both sex and various age groups underwent retinal nerve fiber layer thickness analysis by Stratus OCT 3000 V 4.0.1. The results were evaluated and compared to determine the normal retinal nerve fiber layer thickness measurements and its variations with sex and age. RESULTS: Mean +/- standard deviation retinal nerve fiber layer thickness for various quadrants of superior, inferior, nasal, temporal and along the entire circumference around the optic nerve head were 138.2 +/- 21.74, 129.1 +/- 25.67, 85.71 +/- 21, 66.38 +/- 17.37 and 104.8 +/- 38.81 microm, respectively. There was no significant difference in the measurements between males and females and no significant correlation with respect to age. CONCLUSION: Our results provide the normal retinal nerve fiber layer thickness measurements and its variations with age and sex in Indian population.
