在眼球上施加压力可以使房水的排出率加快,促使眼压下降,根据这样一个简单的道理,Grant于1950年试制了眼压描记器,用以测量房水的流畅系数(简称C值)和房水的形成率(简称F值) C值是在单位时间内房水流出眼球的体积,单位为微升/分钟/毫米汞柱,目前已成为青光眼临床工作中不可缺少的检查方法之一,它对于研究青光眼的诊断,治疗,以及估价予后等均有重要的参考价值。
According to such a simple truth, Grant put pressure on the eye to make aqueous humor discharge rate accelerated, according to such a simple truth, Grant in 1950 pilot trial of the tachymeter to measure the fluid coefficient of aqueous humor (referred to as C value) And aqueous humor formation rate (referred to as F value) C value is the volume of aqueous humor outflow in the unit of time, in units of microliter / min / mmHg, has become an indispensable inspection method in clinical glaucoma, It is for the study of glaucoma diagnosis, treatment, as well as after the valuation has an important reference value.
