Investigate the Effect of Age, Sex, and Refractive Errors on the Central Thickness of the Cornea in Ophthalmology Centers in Jiroft City : association between age, sex, and refractive errors with the central thickness of the cornea

Background: The central thickness of the cornea, as one of the parameters of the anterior segment of the eye, is one of the important factors in the evaluation of patients with eye disorders.  Material and methods: This cross-sectional study was conducted by census method in the summer of 1400 on 255 patients referred to Jiroft ophthalmology centers. Data were collected using a researcher-made checklist and analyzed using SPSS version 22 statistical software and Student's t-tests, one-way analysis of variance, and Pearson's correlation coefficient at a significance level of P < 0.05. Results: 159 people (62.3 %) of the participants were women, and the average age of all people was 34.99 ± 7.33 years. The average central thickness of the cornea in the right eye in the three myopic, binocular and emmetropic groups was 501.93, 519.76, and 512.10, respectively, with the highest average central corneal thickness scores corresponding to the binocular group and the lowest average central thickness scores. The cornea of ​​the myopic group is observed and the results of the analysis of variance showed that there is a statistically significant difference between the three groups in terms of the average scores obtained (P < 0.001). Conclusion: This study showed that age, gender, and refractive errors had a significant effect on the central thickness of the cornea in ophthalmology centers of Jiroft city, and there was a wide range of central corneal thickness values ​​with normal distribution
