Abstract
- We compared the differences of the intraocular pressure measured by the applanation and the Schiotz tonometer according to the ocular rigidity and its changes. We also did it by sex difference, age and the ocular rigidity range. The Korean 254 normal eyes, 12 aphakic eyes, 32 mydriatics treated eyes and 102 myopic eyes were examined. The intraocular perssure was measured by Goldmann applanation tonometer and Schiotz indentation tonometer using the 5.5 gram and 10.0 gram plunger load successively. The ocular rigidity was estimated from the Moses and Becker table. The results were as follows: 1. The mean ocular rigidity of the male and the female Korean was 0.0157 and 0.0195, respectively. There was no significant differences between the two tonometric values. 2. There was no significant ocular rigidity changes according to ages, and there was no statistically significant differences between the two tonometric values, 3. There was no statistically significant differences between the two tonometric values according to the ocular rigidity range. 4. The mean ocular rigidity of normal eyes, aphakic eyes. mydriatics treated eyes and myopic eyes was 0.0183 0.0166, 0.0164 and 0.0170, respectively, and there was no significant differences between the two tonometric values in each groups.
