大学生与高眼压者眼压与角膜厚度、角膜曲率关系

Abstract

目的：研究大学生群体以及高眼压群体的中央角膜厚度(CCT)与眼压测量值(IOP)以及角膜曲率的相关性。方法：应用非接触眼压计(NCT)、A超角膜测厚仪UP-1000和验光仪分别测量广州医科大学在校大学生(31例)和广州医科大学附属第二医院眼科门诊高眼压就诊者(22例)的眼压值、角膜厚度和角膜曲率，观察眼压与各参数之间的关系。结果：将正常眼压组和高眼压组数据合并分析，眼压与角膜厚度不相关(Pearson r = 0.129, P = 0.356)；分别分析，两组各自的眼压与角膜厚度也不相关(Pearson r = 0.153, P = 0.410, Pearson r = 0.048, P = 0.832)。将正常眼压组和高眼压组数据合并分析，眼压与角膜曲率不相关(Pearson r = 0.090, P = 0.541)。分别分析，两组各自的眼压与角膜曲率也不相关(Pearson r = 0.194, P = 0.323, Pearson r = −0.01, P = 0.964)。结论：正常眼压组(大学生群体)与高眼压组的眼压与中央角膜厚度以及角膜曲率不相关。 Objective: to study the correlation between intraocular pressure (IOP) and central corneal thick-ness (CCT), corneal curvature in normal intraocular pressure group of college students and high intraocular pressure group. Method: use non-contact tonometer (NCT), a ultrasound pachymeter UP-1000 and automatic optometry instrument to measure IOP, CCT and corneal curvature of college students with normal IOP in Guangzhou Medical University (31 cases) and outpatients with high IOP of the Second Affiliated Hospital of Guangzhou Medical University (22 cases). Results: ag-gregately analysing, there is no significant correlation between IOP and CCT (Pearson, r = 0.129, P = 0.356) as well as between IOP and corneal curvature (Pearson r = 0.090, P = 0.541); separately analysing, the IOP and CCT of two groups had no significant correlation respectively (Pearson r = 0.153, P = 0.410, Pearson r = 0.048, P = 0.832); the IOP and corneal curvature of two groups had no significant correlation respectively (Pearson r = 0.194, P = 0.323 Pearson, r = −0.01, P = 0.964). Conclusions: there is no correlation between the IOP and corneal thickness, corneal curvature in normal intraocular pressure group of college students and high intraocular pressure group.
