近视眼角膜中央厚度与眼压测量值的相关性分析

目的:探讨近视眼角膜中央厚度(CCT)、屈光度、角膜曲率、年龄、性别与眼压(IOP)测量值之间的关系.方法:对128例256只眼应用超声角膜测厚仪、非接触式眼压计(NCT)、检影镜与电脑验光仪及角膜地形图分别测量角膜中央厚度、眼压、屈光度及平均中央角膜曲率(K).结果:近视眼的角膜中央厚度与眼压值具有直线正相关性,角膜...

Correlation Analysis of Myopia Corneal Thickness and the Pressure Measurements

Objective: To explore the relationship among intraocular pressure(IOP),central corneal thickness(CCT),dioptre,corneal curvature,age,and gender in myopia cases.Methods: IOP,CCT,dioptre,and corneal curvature were determined in 256 eyes of 128 cases of myopia.Results: CCT showed a linear positive correlation to IOP,and IOP increased 0.449 mmHg as CCT increased every 10 μm.No relationship was found between IOP and dioptre,while CCT decreased according to the increasing of dioptre.Corneal curvature,age,and gender had no impact on intraocular pressure of myopia cases.Conclusion: Central corneal thickness is a key factor in relation to intraocular pressure.It is very important that intraocular pressure should be determined according to central corneal thickness for glaucoma screening in order to avoid misdiagnosis.
