| Summary: | Objective: To determine the distribution of central corneal thickness (CCT) among Filipinos and to correlate CCT with intraocular pressure (IOP).
Methods: A prospective cross-sectional study was performed among Filipino patients consulting at the General Ophthalmology Clinic of the Philippine General Hospital. They underwent a comprehensive eye examination. CCT obtained by ultrasonic pachymetry and IOP by Goldmann applanation tonometry were correlated using linear regression analysis. Factors affecting CCT measurements were analyzed by ANOVA.
Results: Two hundred twenty two eyes of 112 patients were included in the study. CCT ranged from 451.0 m to 653.6 m with a mean of 531.5 m ±33.8 m. There was a significant linear correlation between CCT and IOP (r = 0.63). The IOP was noted to rise by 4.3 mm Hg/100 m CCT.
Conclusion: The CCT among Filipinos is normally distributed and is comparable to the distribution obtained by metaanalysis of worldwide data. The study also found a direct correlation between CCT and IOP among Filipinos. |
