Central Corneal Thickness from a Subset of Normal Population in Pakistan Using Anterior Segment Optical Coherence Tomography

Abstract

Objective: To measure central corneal thickness and study its association with intraocular pressure (IOP), age and gender.

Study Design: Cross-sectional study

Place and Duration of Study: This study was conducted at the tertiary eye care health centre during Feb 2019 and Feb 2020 for one year.

Materials and Methods: 324 normal individuals were recruited. They followed the routine eye examination protocol and in the end we performed anterior segment OCT on one eye of each participant.

Results: The mean CCT was found to be 533.01µm and mean the IOP was 12.6mmHg. When we compared CCT with age, significant correlation was not found (Pearson’s correlation coefficient (R) = 0.022, P-value = 0.692). Similar results were obtained when CCT was tested against IOP (Pearson’s correlation coefficient (R) = 0.056, P-value = 0.315). The difference of CCT between the two gender was also not significant (p-value = 0.774).

Conclusion: The CCT from our study was not found to be associated with age and intraocular pressure. Also the difference in CCT values of males and females was not statistically significant.
