Aim: To assess the intrasubject variability of CCT,IOP and VCDR in patients with POAG compared to normal.
Design: Cross sectional study.
Materials and Methods: A total of 100 eyes of patients on treatment for POAG and 100 eyes of normal individuals were included in the study. All patients underwent a complete ophthalmological examination including CCT corrected IOP, visual field by HFA and disc evaluation using 90D assisted slit lamp biomicroscopy. CCT was measured using ultrasonic pachymetry in all of them. The difference in IOP, Vertical CD ratio and CCT were compared between the two eyes in POAG patients and in normal individuals.
Results: The mean difference in IOP was 3.52±3.8 in POAG group compared to 1.06±0.9 in normal .The mean difference in CD ratio was 0.132±0.15 in POAG compared to 0.05±0.07 in normal. The mean difference in CCT was also significantly higher in POAG patients. [8.10±7.4] when compared to normal individuals [5.05±5.17].

Keywords: Central Corneal Thickness, Intraocular pressure, Inter ocular variability, Vertical cup disc ratio
