In previous studies, it has been shown that the central corneal thickness influences the measurement values of applanation tonometry. The aim of this study is to answer the question as to which values and with what frequency the tonometer readings as based on corneal thickness have to be corrected in the patients attending an ophthalmic practice.
The corneal thickness was measured in 579 patients using ultrasound pachymetry under the conditions prevailing in a medical practice; from the thickness obtained, the correction values for intraocular pressure were calculated.
Correction values of +/-2 mm Hg and above were found in half of the patients examined, and correction values of +/-3 mm Hg and above in a good quarter of the patients. The correction value was +/-4 mm Hg and more in every fifth patient.
Corneal thickness does, in fact, influence the results of applanation tonometry to a clinically relevant degree.
在先前的研究中已表明，中央角膜厚度会影响压平眼压计的测量值。本研究的目的是回答在眼科诊所就诊的患者中，基于角膜厚度的眼压计读数需要校正哪些值以及校正频率是多少的问题。
在医疗实践的常规条件下，使用超声测厚仪对579例患者测量角膜厚度；根据测得的厚度计算眼压校正值。
在一半的受检患者中发现校正值在±2 mmHg及以上，在四分之一的患者中校正值在±3 mmHg及以上。每五分之一的患者校正值为±4 mmHg及更高。
事实上，角膜厚度对压平眼压计的测量结果有临床相关程度的影响。
