探讨角膜厚度 (CCT)对眼压 (IOP)测量的影响及其临床意义。方法 :用超声角膜测厚仪及非接触式眼压计检测 2 88例眼科患者 5 0 0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 2 7μm,IOP将随之增加 lmm Hg)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
To investigate the influence of corneal thickness (CCT) on intraocular pressure (IOP) measurement and its clinical significance. Methods: The CCT and IOP in 888 ophthalmology patients were detected by echocardiography and non-contact tonometer. Results: The IOP was positively correlated with the increase of CCT (the increase of IOP was increased by 1 mm Hg for every 27 m CCT increase), but not with the degree of diopter. CCT was negatively correlated with patient age. Conclusions CCT is an important factor affecting the detection of IOP. Examining CCT can help to estimate more correctly IOP, which can be used as an important index to identify some clinical diseases
