1、中央角膜较厚的髙眼压症者临床随访观察【摘要】目的：探讨高眼压症者屮央角膜厚度(CCT)与眼压(IOP)的关系，观察CCT在判断高眼压症者是否给予降眼压治疗中的临床价值。方法：对113例(226眼)高眼压症者进行超声角膜厚度测量和非接触眼床计(NCT)测眼床，对校止眼床＜21mmHg者52例(104眼)不给予降眼压药物治疗，跟踪观察其眼床、视野、生理杯和视网膜神经纤维层的变化。结杲：IOP随CCT呈正相关变化，CCT每增加100Um,IOP将随之增加1.86mmHgo对校正眼压＜21mmHg者不予以降眼压治疗，跟踪观察12〜36个月，只有3例(6眼)出现视野和视神经纤维层改变，发生率为
2、2.66%(6/226)。结论：中央角膜厚度测量可以作为高眼压症与开角型青光眼进行鉴别诊断、以及判断高眼压症能否发展成为青光限的可靠依据，对高眼压症者要常规进行角膜厚度测量并校止其眼压，校止眼压＜21mmHg者，可不用降眼压药物干预。【关键词】高眼压症;中央角膜厚度；校正眼压;青光眼FollowclinicalobservationofocularhypertensionofthecentralcornealthicknessCAOXian-Yong,HELin,LIYan-hua(OphthalmologyoftheThirdAffiliatedHospitalofXinxiang
