角膜厚度对眼压测定的影响

目的：探讨角膜厚度（CCT）对眼压（IOP）测量的影响及其临床意义。方法：用超声角膜测厚仪吸非接触式眼压计检测288例眼科患者500眼之CCT及IOP进行统计学分析。结果：IOP随CCT增加而增高并成正相关（CCT每增加27μm，IOP将随之增加1mmHg）而与屈光度无关，CCT与患者年龄成负相关。结论：CCT为影响IOP检测的一个重要因素，检查CCT有助于更正确的估计IOP，可以作为鉴别某些临床疾病的重要指标。

Effect of central corneal thickness on measurement of intraocular pressure

Objective: To evaluate the effects and its clinical significance of central corneal thickness (CCT) on the measurement of intraocular pressure (IOP). Methods: The CCT were measured with ultrasonic and IOP with noncontact tonometer in 500 eyes of 288 patients, the data were analyzed statistically Results: There was a significant positive correlation between CCT and IOP. An increase in CCT of 27 microns was associated with an increase in IOP measurement of 1 mmHg. A significant negative correlation was identified between CCT and age, but there was no correlation between IOP and diopters. Conclusions: CCT is an important factor for the reading of IOP. Examining CCT is helpful in evaluating IOP appropriately and distinguishing some eye diseases.
