Measurement of Episcleral Venous Pressure in Normal Chinese People

摘要

Purpose: To measure episcleral venous pressure (EVP) in normal Chinese people. Methods: EVP was measured in 110 eyes of 74 subjects distributed in seven age groups from 10 to 80 years using episcleral venomanometer (EV-310). The differences in EVP values were analyzed with age and either eye.Results: EVP values of the 110 eyes appeared as normal distribution. The value x±SD was (9. 11±1. 22) mmHg, and the 95% normal value range was 6. 73 mmHg ~ 11. 50 mmHg. No statistically significant difference of EVP was found in the seven age groups. And there was no statistically significant difference of EVP between the right and left eyes. Conclusions: The value x ?SD of EVP in Chinese normal eyes is 9. 11 mmHg±1.22 mmHg. The normal value of EVP does not vary with age and either eye. Eye Science 2000; 16: 172- 175.
