Determination of Central Corneal Thickness in Patients with Refractive Anomalies and Emmetropy

Abstract

Aim: The purpose of this study was to compare measurements of CCT in emmetropia and patient with refractive anomalies. Methods: We represent a retrospective research which was conducted at the University Clinical Center of Kosovo (UCCK). In this study were included 80 patients, divided into two groups: test and a control group. Mean age was (M = 25.90, DS = 7.16), men (N = 41% or 51.3%) and women (N = 39% or 48%). Results: Results show that there were no differences in the CCT, Hyperopic (M = 545.21 DS = 52.24), Myopic (M = 547.90 DS = 47.93) and Emmetropic (M = 550.75 DS = 41.29). After measuring of the longitudinal axis and analyzing the data by means of Anova test, it appeared to be a significant difference between the analyzed groups, Hyperopic (M = 21.99, DS = 1.27), Myopics (M = 23.21, DS = 1.24), Emmetropic (M = 22.36, DS = 0.81). Results also revealed that there is correlation between the CCT and IOP, where increase CCT decreases IOP and vice versa (r = −0.26, p = 0.01). Conclusion: The results have shown that CCT is thinner in myopic but does not show correlation with hypermetropic and emmetropic. While during the measurement of central corneal thickness and eye tension it is found that there is a negative correlation between them. Keratometry has a negative correlation with CCT. While there was no correlation between CCT and age. Given the role of CCT in interpreting IOP values, it is recommended to perform a systematic CCT measurement in routine clinical practice, which would assist in the diagnosis of ocular hypertension.

“…26 A study by Ismaili et al, which was carried out on 80 patients with refractive eye errors at the Kosovo University Clinic with an age range of 19-38 years, also obtained the same result, namely that there was no significant relationship between age and central corneal thickness. 27 Meanwhile, Mashige stated that with age, there is a reduction in central corneal thickness due to decreased keratocyte density. 9 This difference in results may occur because the central corneal thickness is said to be related to genetics, so because there are differences in the study population, the results obtained may also be different.…”
