Abstract: Purpose: To study the optic disc topographic measurements of normal Indian eyes using optical coherence tomography (OCT). Materials and Methods: One hundred and fifty eyes selected randomly from 150 normal Indian subjects of both sex and various age groups underwent optic disc imaging with the OCT using the fast optic disc protocol. Results: Mean +/- standard deviation of the optic disc topographic measurements were: disc area 2.63 +/- 0.55 mm 2 , cup area 0.87 +/- 0.45 mm 2 , neuroretinal rim area 1.78 +/- 0.55 mm 2 and cup to disc area ratio 0.33 +/- 0.15. There was no significant difference in the measurements between males and females. There was no significant correlation with respect to age and refractive errors ranging from -5.0 to +3.0 diopters of spherical equivalent. Conclusion: Our study provides a normative database for the various optic disc topographic measurements and its variations with age, sex and refractive error in normal Indian eyes using OCT.
