Abstract:

为了探讨兔眼前节内前后房压强差随时间变化的规律,设计了一套前后房压强差在体测量装置。利用连通器原理,搭建在体测量眼内前后房压强差的平台。通过注射复方卡波姆升高眼压的方法构建高眼压兔眼模型,实现正常和高眼压兔眼的前后房压强差的在体 24 小时连续测量。设计的本装置对于眼内微小的压强差会产生比较敏感的反应。正常兔眼前后房压强差随时间变化,一天的变化范围为 5.84~96.84 Pa,反映出生理性规律的存在。高眼压性兔眼多呈现前房压强高于后房压强的状况,符合自适应性调整学说。本文所设计的方法和装置可以较好地实现眼内前后房压强差的测量,且前后房压强差在一天当中随时间呈规律性变化
