摘要

目的探讨屈光状态和角膜中央厚度(CCT)对Goldmann眼压测量(GAT)的影响。方法选取119例正常人(195眼)和74例近视眼(148眼)作为研究对象。用Pentacam测定CCT，用GAT测定眼压。采用SPSS17.0软件对数据进行处理。结果正常组CCT平均值为(525.07±38.58)μm。平均眼压为(12.96±2.64)mmHg。低近视组与正常组的IOP及平均CCT差异有统计学意义。高度近视组与正常组的IOP差异有统计学意义。近视组的IOP与屈光度呈负相关(r=-0.396, P <0.001)。每增加-3.86D，眼压升高1mmHg。正常组和近视组的IOP矫正公式分别为1mmHg/45.55μm、1mmHg/34.46μm。结论CCT和屈光状态对IOP有影响。关键词:折射状态;角膜中央厚度;戈德曼压平测压法;Pentacam;IOP校正

The effects of refractive status and central corneal thickness on applanation tonometry measurements

Objective To investigate the effect of the refractive status and central cornea thickness (CCT) on Goldmann applanation tonometry (GAT). Methods A total of 119 cases of normal subjects (195 eyes) and 74 cases of myopia (148 eyes) were included in this study. The CCT was measured by Pentacam and intraocular pressure (IOP) by using GAT. SPSS17.0 was used to process the data. Results The average CCT of the normal group was (525.07±38.58)μm. The mean IOP was (12.96±2.64)mmHg. The difference on both IOP and the mean CCT between low myopia group and normal group had statistically significant. The difference in IOP between high myopia group and normal group had statistically significant. The IOP of myopia group was negatively correlated with diopter (r=-0.396, P <0.001). IOP increased 1mmHg with per -3.86D increase. IOP of normal and myopic groups correction formulas were 1mmHg/45.55μm, 1mmHg/34.46μm, respectively. Conclusions CCT and refractive state can influence IOP. Key words: Refractive status; Central corneal thickness; Goldmann applanation tonometry; Pentacam; IOP correction

期刊介绍： China Practical Ophthalmology was founded in May 1983. It is supervised by the National Health Commission of the People's Republic of China, sponsored by the Chinese Medical Association and China Medical University, and publicly distributed at home and abroad. It is a national-level excellent core academic journal of comprehensive ophthalmology and a series of journals of the Chinese Medical Association. China Practical Ophthalmology aims to guide and improve the theoretical level and actual clinical diagnosis and treatment ability of frontline ophthalmologists in my country. It is characterized by close integration with clinical practice, and timely publishes academic articles and scientific research results with high practical value to clinicians, so that readers can understand and use them, improve the theoretical level and diagnosis and treatment ability of ophthalmologists, help and support their innovative development, and is deeply welcomed and loved by ophthalmologists and readers.
