(一)高眼压和慢性单纯性青光眼普查正常人群的眼压平均值为15mmHg,标准差约3mmHg;统计未经治疗的伴有视野缺损的慢性单纯性青光眼病人,眼压平均值为24mmHg,标准差约5mmHg。正常人群的眼压呈非正态分布,向高眼压方向偏斜,而老年人及女性的眼压统计值又倾向于偏高。很明显,正常人与慢性单纯性青光眼患者的眼压分布范围之间有很大区域的重叠。Armaly统计,在正常人群中眼压(P_0)高于21mmHg者占8%左右。Harbin指出,年龄在40岁以上的人群中眼压高
(A) of the normal intraocular pressure and chronic simple glaucoma census IOP average 15mmHg, standard deviation of about 3mmHg; statistics untreated chronic simple glaucoma accompanied by visual field defect patients, the average intraocular pressure was 24mmHg, Standard deviation of about 5mmHg. The normal population intraocular pressure showed a non-normal distribution, to the direction of high intraocular pressure bias, and the elderly and women’s intraocular pressure statistics and tend to be high. Obviously, there is a large overlap between the distribution of intraocular pressure in normal subjects and patients with chronic simple glaucoma. Armaly statistics, in the normal population IOP (P_0) higher than 21mmHg accounted for about 8%. Harbin notes that IOP is elevated in people over the age of 40
