BACKGROUND: Estimates of intraocular pressure (IOP) are influenced directly by the central corneal thickness (CCT). We assume and apply a single value for CCT (520 mum) in applanation tonometry estimates, although there is compelling evidence that CCT varies between individuals.
OBJECTIVE: To determine the influence of CCT and other factors on IOP among Ethiopians.
METHODS: A cross sectional study was conducted among 300 sampled individuals from June to July 2006. The CCT was measured using OcuScan(R) RxP Ophthalmic Ultrasound and readings of IOP were made with Goldmann applanation tonometer. The data was analyzed using SPSS version 12 and S-Plus 2000 of statistical packages.
RESULTS: Out of 300 individuals, 184 (61.3%) were males. The mean age was 42.57 years (SD+/-16.71), mean IOP 13.39 mm Hg (SD+/-2.81), and mean CCT 518.68 mum (SD+/-32.92). There was statistically significant relationship between CCT and IOP (r=0.199, P<0.001) and a borderline statistically significant detectable change of CCT with age (r=0.012
