Purpose: The aim of the research project is to study the effects of central corneal thickness (CCT), axial length (AL), and anterior chamber (ACD) depth on intraocular pressure (IOP). Study Period: It was a cross-sectional study and was conducted from February 2015 to June 2015. Methodology: A total of 100 participants of varying age groups were selected from Qassim University clinics who had clinically normal corneas and then were divided into different groups based on their ages. All the participants had no evidence of any ocular disease and both eyes were examined in each participant. Anterior chamber depth (ACD) and CCT were measured with Pentacam (OCULUS). IOP was measured with air puff tonometer. AL was measured by A-scan ultrasonography. Results: Two hundred eyes of one hundred participants were examined. The ages of the participants ranged between 18 and 30 years. Mean age was 23.94 years with ± 2.994 standard deviations The number of emmetropes, myopes, and hypermetropes was 50, 19, and 31, respectively. The mean corneal thickness in the right eye was 541.64 μm (±34.80) and in the left eye, it was 543.46 μm (±33.65). IOP was found to increase with increased CCT and it was statistically significant (P < 0.001). There was a positive correlation between refractive errors, CCT, and IOP. On the other hand, very weak correlation was observed between IOP and AL and ACD. Conclusion: It can be concluded that people with increased CCT and steep cornea need to be monitored closely for their IOP because of strong positive correlation between increased corneal thickness and IOP and high IOP should not be considered as the only factor for diagnosis and it should be related with optic disc evaluation and visual field examination to avoid the over treatment.
