Abstract
- The normal intraocular pressure which are known to us are the standards of ocular pressure obtained by testing foreigners. According to the reports, the scope of normal I.O.P. is 15-25 mmHg. However, in the case of our neighboring Japanese the scope of normal I.O.P. is 10-15 mmHg and its average is 18.11 mmHg by Schiotz's tonometer. In order to study the I.O.P. of Korean, the writers of this report have tested 405 normal persons(810 eyes) and herewith report the results obtained from the tests. Conclusion: 1. The I.O.P. of 405 normal Koreans is as follows. Reliability range: 12-19 mmHg, Average Value: 15.5 mmHg. 2. As for the diurnal variation, the minimum mean of 10.8 mmHg was found at 1.00 P.M. and the maximum mean of 16.5 mmHg was found at 7.00 A.M. the standard error in each was 0.28 and 0.50 respectively and its difference was 4.5. 3. No difference was found by age or sex.
