Introduction: Considering the increasing prevalence of myopia and the subsequent complications, and due to the dearth of studies on the correlation between myopia and gender with corneal thickness in Iran, this study aimed to determine this relationship in patients admitted to the ophthalmic clinic of Vali-e-Asr Hospital, Birjand, Iran. Methods: This descriptive-analytic epidemiologic study was conducted on ۱۰۰ patients admitted to Vali-e-Asr ophthalmic clinic in Birjand, Iran, for one year since January ۲۰۱۷. According to the degree of myopia, the patients were divided into three groups of low (۰-۳ D), moderate (۳-۶ D), and high myopia (۶≤D). Corneal thickness was measured using Orbscan and Pentacam. The data were analyzed in SPSS software (Version ۱۹) through ANOVA and T-test to determine the possible relationship between myopia and central corneal thickness. A p-value equal to and less than (P≤۰.۰۵) was considered statistically significant. Results: Overall, ۱۰۰ patients (۴۹ males and ۵۱ females) were enrolled in this study. Moderate myopia had the highest frequency in both eyes. The results of the T-test revealed that no significant difference was observed in the mean corneal thickness measured by Pentacam between the two genders (P=۰.۱۸ in the right eye and P=۰.۳۲ in the left eye). Based on the ANOVA findings, the mean corneal thickness measured by Pentacam was not significantly different among the myopia categories (P=۰.۰۵ in the right eye and P=۰.۵۱ in the left eye) Conclusions: The study results revealed that there was no significant relationship between myopia and gender with corneal thickness.
