Comparison of Corneal Thickness of Young People with Middle and High Myopia between Shantou and Zhengzhou
摘要
Purpose:To compare the corneal thickness of young subjects (aged 18 to 30 years).with moderate and high myopia living in Shantou and Zhengzhou.Methods:One hundred and forty myopic subjects from Shantou (Guangdong,southern China) and 101 from Zhengzhou (Henan,central China)were selected and divided into 2 groups (moderate-myopic group and high-myopic group).The participants were sex-and age-matched.The central corneal thickness (CCT) and thinnest corneal thickness (TCT) were measured by Orbscan and compared between the two groups.Results:In the high-myopic group,CCT (515.47±40.39 μm) and TCT (510.22±40.95 μm) of the Shantou subjects (mean spherical equivalent.[SE]-7.56±1.35),were thinner than those of their Zhengzhou counterparts.(mean SE-7.47 ±0.88).In the moderate-myopic group.(Shantou mean SE-4.52 ±0.83;Zhengzhou-4.67 ± 0.77),CCT and TCT did not differ between the two cities.Conclusion:The corneal thickness of high-myopic eyes may differ between Shantou and Zhengzhou.
