Studies done on Indian eyes at Sankara Netralaya,Chennai and Suraj Eye Institute,Nagpur showed the following results:
The mean CCT for the South Indian adult population was 511.4+/-33.5 microm, and CCT in males (515.6+/-33.8 microm) was significantly (P = 0.0001) greater than females (508.0+/-32.8 microm). The CCT was significantly greater (by 18 microm) in the urban population and decreased with age in both genders (P<0.0001).
Among Indian subjects from Central India the mean CCT was 514+/-33 microm (median, 517 microm; range, 290-696 microm).Central corneal thickness and steepness of the anterior corneal surface may thus both have to be taken into account when applanation tonometry is performed the study concludes.
Thus these studies have implications on the diagnosis and management of Glaucoma.
