眼压测量值的影响因素及常用眼压计比较

Factors affecting intraocular pressure measurement and comparison of different tenonometers

眼压检查是青光眼诊断和检测的重要指标之一,很多因素可能会影响眼压测量值,如中央角膜厚度、屈光度、体位以及患者全身因素等。其中,中央角膜厚度目前被发现是影响眼压测量值最主要的因素。临床上眼压计种类繁多,我们选取了几种常用的眼压计进行比较,分析其测量眼压的准确性、适用场合及优劣势。

Intraocular pressure is one of the most important indexes for the diagnosis and monitoring of glaucoma. A lot of factors may affect the intraocular pressure measurement such as central corneal thickness, refractive error, position, and systemic factors of patients, etc. Among them, central corneal thickness was found to be the most important factor affecting the measurement of intraocular pressure. There is a wide variety of tenonometers clinically. We selected several common tenonometers for comparison, analyzing their accuracy, applicable scope, advantages and disadvantages for a reference.
