Abstract

PURPOSE To investigate the correlation of various corneal hysteresis (CH) factors in Chinese adults. METHODS From January 2009 to November 2011, the healthy right eyes of a total of 292 adults were recruited into the study. Goldmann-correlated intraocular pressure (IOPG) and CH were measured using an ocular response analyzer (ORA). Central corneal thickness was measured using the ORA's integrated handheld ultrasonic pachymeter. The IOLMaster was used to obtain the ocular biometric measurements including axial length, anterior chamber depth, and keratometric values. The Pearson correlation coefficient was used to test correlations between CH and quantitative factors. The chi-square test was used to detect differences in categorical values. RESULTS Longer axial length (P = 0.0001), lower IOPG (P = 0.03), older age (P = 0.003), and thinner central corneal thickness (P = 0.0001) were significantly associated with lower CH. The anterior chamber depth (P = 0.34), gender (P = 0.23), and corneal curvature (P = 0.18) had no relationship to CH. CONCLUSION Various factors including axial length, intraocular pressure, age, and central corneal thickness can affect measurement of corneal biomechanical properties in Chinese adults. But the anterior chamber depth, gender, and corneal curvature were irrelevant to CH.

台湾成人角膜迟滞之影响因素。

目的探讨中国成人角膜迟滞(CH)各因素的相关性。方法2009年1月至2011年11月，选取健康成人右眼292例。使用眼反应分析仪(ORA)测量goldmann相关眼压(IOPG)和CH。使用ORA的集成手持式超声测厚仪测量角膜中央厚度。使用IOLMaster获得眼生物测量数据，包括眼轴长度、前房深度和角膜测量值。采用Pearson相关系数检验CH与定量因子之间的相关性。使用卡方检验来检测分类值的差异。结果较长的眼轴长度(P = 0.0001)、较低的眼压(P = 0.03)、较老的年龄(P = 0.003)、较薄的角膜中央厚度(P = 0.0001)与较低的CH相关，而前房深度(P = 0.34)、性别(P = 0.23)、角膜曲率(P = 0.18)与CH无关。结论眼轴长度、眼压、年龄、角膜中央厚度等因素对中国成年人角膜生物力学特性的测量有影响。但前房深度、性别和角膜曲率与CH无关。

期刊介绍： Eye science was founded in 1985. It is a national medical journal supervised by the Ministry of Education of the People's Republic of China, sponsored by Sun Yat-sen University, and hosted by Sun Yat-sen University Zhongshan Eye Center (in October 2020, it was changed from a quarterly to a monthly, with the publication number: ISSN: 1000-4432; CN: 44-1119/R). It is edited by Ge Jian, former dean of Sun Yat-sen University Zhongshan Eye Center, Liu Yizhi, director and dean of Sun Yat-sen University Zhongshan Eye Center, and Lin Haotian, deputy director of Sun Yat-sen University Zhongshan Eye Center, as executive editor. It mainly reports on new developments and trends in the field of ophthalmology at home and abroad, focusing on basic research in ophthalmology, clinical experience, and theoretical knowledge and technical operations related to epidemiology. It has been included in important databases at home and abroad, such as Chemical Abstract (CA), China Journal Full-text Database (CNKI), China Core Journals (Selection) Database (Wanfang), and Chinese Science and Technology Journal Database (VIP).
