正常人泪液PH值报告不同,在国外文献报告从1921年以后为5.2～8.6。在测定正常值时从技术上发生的误差多是由于造成泪液中CO_2的丢失所致。其测定方法有用试纸法或用微型PH测定器。我们采用精密试纸测定了150人(300眼)健康无眼病的正常人泪液PH值。
Normal tear fluid PH value of different reports in foreign literature from 1921 to 5.2 ~ 8.6. In the determination of normal from the technical errors are mostly caused due to the loss of CO 2 in the tear. The method of determination of useful test strips or micro-PH test device. We used precision test strips to determine the pH value of tears in 150 normal people (300 eyes) without eye diseases.
