Aim: To compare the variation in stereoscopic vertical cup disc ratio examination with 90 D lens Vs. Cirrus HDOCT. Material and Methods: This is a retrospective study of all cases in which Cirrus HD-OCT was done for glaucomatous disc evaluation in the month of January 2016 and examined by single experienced glaucoma specialist. It includes 94 eyes of 49 patients (4 patients were one eyed). Difference of vertical cup disc ratio between 90 D and Cirrus HD-OCT was noted, values less than 0.1 were considered as comparable while the values more than or equal to 0.1 were considered as non-comparable. Results: Age of the patients was 44.26 ± 17.89 years (mean ± SD). Out of 49 patients, 65.31% (32) were males and 34.69% (17) were females. Vertical Cup disc ratio was comparable in 92.55% (87) and found to be noncomparable in 7.45% (7) of eyes with Cirrus HD-OCT. Conclusion: Stereoscopic vertical cup disc ratio examination with 90 D lens was found to be comparable with Cirrus HD-OCT in majority of the cases.
