Association of Central Corneal Thickness in Myopes - A Hospital Based Study

Abstract

Background:  The prevalence of myopia has been increasing steadily, and studies on the relationship between myopia and central corneal thickness (CCT) have shown conflicting results. The purpose of this study was to investigate the relationship between myopia and CCT in a hospital based population from kancheepuram.

Materials & Methods: This study was conducted at a tertiary care facility in Kanchipuram between January and December 2023. A total of 100 patients aged 11 to 40 years with myopic refractive error (spherical equivalent [SE] greater than -0.5 D) as determined by cycloplegic refraction were included in the study. The collected data was entered in Microsoft Excel. Coding of the variables was done. Analysis was done using SPSS software (Version 27, IBM).

Results: This study included 200 eyes of 100 individuals with varying grades of myopia. 60% (n = 60) of the study participants were females. The mean age of the study participants was 27.68 ± 7.25 years (range: 12–40 years). The mean SE was − 2.61 ± 1.34 D (range: -0.5 to -6.0 D). The mean CCT was 541.53 ± 57.18 µm (range: 441–664 µm).

Conclusion: We analyzed the CCT measurements using non-contact specular microscopy in individuals with mild to moderate myopia. The average CCT values did not show a correlation with the myopic SE. Further research with a larger sample size and various degrees of myopia is necessary to better understand the relationship between myopia and CCT.
