“高眼压”的现代定义是:眼压高于20或21mmHg的正常范围,但房角开放、视乳头及视野无青光眼性改变。高眼压病例发生青光眼性病变的危险性不超过5-10%,但会随其眼压的升高而增多。不过其眼压与青光眼性病变的发生没有绝对的关系。眼压以外的其他因素起着重要作用,但这些对眼压敏感的因素尚未全然了解。 1.眼压的变化:讨论某一眼的眼压时,倾向于将眼压看作是一个恒定的因素,而不考虑眼压可能随着时间的改变而有所变化。Armaly研究以压平眼压计测量的一次眼压的可靠性,对1,000多眼每年测量一次共5年的眼压进行分析,发现眼压的变易性接近10%。
The modern definition of “high intraocular pressure” is: intraocular pressure higher than the normal range of 20 or 21mmHg, but the open angle, optic disc and visual field glaucoma change. High intraocular pressure cases of glaucomatous lesions do not exceed the risk of 5-10%, but will increase with its intraocular pressure. However, its intraocular pressure and glaucoma lesions do not have an absolute relationship. Other factors than intraocular pressure play an important role, but these IOP-sensitive factors have not been fully understood. 1. Changes in IOP: When discussing the IOP of a particular eye, IOP tends to be viewed as a constant factor irrespective of the change in IOP that may change over time. Armaly studied the reliability of an IOP measured with a tonometer and analyzed intraocular pressure measured over 1,000 eyes annually for 5 years and found intraocular pressure variability of nearly 10%.
