Abstract

Abstract: : Purpose: To determine the correlation between central corneal thickness (CCT) and scleral thickness. Methods: CCT was measured using ultrasonic pachymetry. Measurements were based on an average of 15 values. Scleral thickness was measured using ultrasound biomicroscopy 2 mm posterior to the scleral spur at the temporal meridian. Patients with incisional surgery at the temporal meridian were excluded. Examiners were masked to the results of the fellow test. Furthermore, we correlated CCT and scleral thickness with the refractive errors of the patients enrolled in the study by calculating a spherical equivalent for each patient. Results: 50 patients were enrolled. Mean age was 58.5 ± 14.3 years. Mean CCT was 565.0 ± 42.5 µm. Mean scleral thickness was 550.5 ± 43.1 µm. There was moderate correlation between CCT and scleral thickness. (r=0.59, Pearson`s p<0.001). Correlating refractive error with CCT and scleral thickness we found r2 = 0.1342, p = 0.0145, and r2 = 0.1208, p = 0.0208, respectively. Conclusion: CCT and scleral thickness have a moderately positive correlation. There is no statistically significant correlation between CCT and refractive error and scleral thickness and refractive error. CR: none.
