Central corneal thickness and intraocular pressure in Puerto Rican glaucoma patients

Abstract

Objective: To compare the variations in central corneal thickness and intraocular pressure measurements according to race, gender, and age. Methods: A non-concurrent prospective study of 372 (744 eyes) glaucoma patients was conducted. Central corneal thickness was measured with ultrasound pachymeter and intraocular pressure with Goldmann tonometer. The relationship between CCT, race, gender, and age was evaluated using both descriptive and statistical analysis. Results: The population age was 64 ± 19.52 years. The mean central corneal thickness was 546 ± 43.84 μm. The mean corrected intraocular pressure was 17 ± 5.26 mm Hg. Central corneal thickness of male patients (549 ± 43.43 μm) was thicker than that of female patients (546 ± 41.83 μm). The mean corrected intraocular pressure in male patients (16 ± 5.41 mm Hg) was less than that of female patients (17 ± 5.18 mm Hg). The mean central corneal thickness in patients 0 to 9 years-of-age was 548 ± 36.08 μm; 10 to 19 years-of-age was 606 ± 82.30 μm; 20 to 29 years-of-age was 564 ± 29.23 μm; 30 to 39 years-of-age was 579 ± 15.32 μm; 40 to 49 years-of-age was 546 ± 48.29 μm; 50 to 59 years-of-age was 550 ± 38.12 μm; 60 to 69 years-of-age was 545 ± 40.22 μm; 70 to 79 years-of-age was 541 ± 34.71 μm; 80 to 89 years of-age was 541 ± 34.05 μm; older than 90 years-of-age was 527 ± 46.90 μm. Conclusions: Central corneal thickness of glaucoma patients in Puerto Rico was similar to that of Hispanics in the continental United States. However, the intraocular pressure and corrected intraocular pressure of glaucoma patients in Puerto Rico were statistically higher than that of Hispanics with glaucoma in the continental United States. In our study population, central corneal thickness and intraocular pressure were not affected by gender or age.
