The Relationship between Intra-Ocular Pressure and Central Corneal Thickness in Saudi Population
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2014, Vol 2, Issue 6
Abstract
The aim of this study was to determine, and relate Central Corneal Thickness and Intra-ocular pressure in healthy Saudi people. A prospective, cross-sectional, observational study was performed that included 200 normal Saudi adult individuals. Intra-ocular pressure was measured by the ocular response analyzer and Goldman Applentation Tonometry. The central corneal thickness (CCT) was measured using Pentacam system. The mean IOP was 15.12+3.5. Mean A positive correlation was found between CCT (r= 0.447, p value=0.000) and IOP mm Hg (r= 0.878 and p value=0.000). A positive correlation was found between CCT (r=0.412, p value 0.000) and IOP g (r=0.183, p value 0.007). This study demonstrated a linear relationship between Intra-ocular pressure and CCT. This would suggest the effect of pathological corneal thinning (ectasia) to have underestimation of the Intra-ocular pressure, and corneal edema can overestimate the Intra-ocular pressure. Keywords: Central Corneal Thickness, Intra-ocular pressure (IOP), Corneal Hysteresis (CH), Ocular response analyzer, Goldman applentation tonometry, Pentacam system.
