浅层巩膜静脉压在眼房水动力学中有重要作用,但因数值测定困难,迄今研究尚不充分。为查明原发性青光眼、高眼压症和高血压病人浅层巩膜静脉压的差别,作者观察了年龄20—70岁的84例139眼。结果如下:闭角型青光眼(16眼)平均14.55±0.9mmHg;高眼压症(13眼)平均10.31±0.78mmHg;健康人(40眼)平均9.68±0.48mmHg;开角型青光眼(37眼)平均9.41±0.33mmHg;高血压(33眼)平均9.87±0.48mmHg。闭角型青光眼病人浅层巩膜静脉压和所有被检查组有明显差别,与开角型青光眼差别最明显,相差5.41mmHg。20—29岁各组的浅层巩膜静脉压平均压力为8.5mmHg。30—35岁无明显升高,30—50岁为10.66mmHg。波动范围:开角型青光眼4.4—12.9mmHg,闭角型青光眼7.4—16.2mmHg。一眼各象限相差2—3mmHg,故应取若干象限的平均值。因浅层巩膜静脉压有个
Shallow scleral venous pressure plays an important role in the hydrodynamics of the aqueous humor. However, the numerical determination is difficult and so far it has not been fully studied. To identify the differences in superficial scleral venous pressure between primary glaucoma, ocular hypertension and hypertensive patients, the authors observed 84 eyes of 139 eyes aged 20-70 years. The results were as follows: closed angle glaucoma (16 eyes) average 14.55 ± 0.9mmHg; ocular hypertension (13 eyes) average 10.31 ± 0.78mmHg; healthy people (40 eyes) average 9.68 ± 0.48mmHg; open-angle glaucoma ) Averaged 9.41 ± 0.33 mmHg; hypertension (33 eyes) averaged 9.87 ± 0.48 mmHg. Shallow scleral venous pressure in patients with angle-closure glaucoma was significantly different from that of all examined patients, with the most obvious difference being open-angle glaucoma, with a difference of 5.41 mmHg. The average pressure of superficial scleral venous pressure in each group of 20-29 years old was 8.5mmHg. No significant increase in 30-35 years old, 10.66mmHg 30-50 years old. Fluctuation range: open angle glaucoma 4.4-12.9mmHg, closed angle glaucoma 7.4-16.2mmHg. A difference of 2-3mmHg quadrants, it should take the average of a number of quadrants. Because of the shallow scleral vein pressure there
