Abstract
- The measurement of the intraocular pressure were made with the Mackay-Marg electronic applanation tonometer, as compared with standard Goldmann tonometer and Schiotz tonometer in Korean 114 normal eyes. The results were as follows: 1. The mean intraocular pressure of 114 normal eyes was 16.61 +/- 3. 77 mmHg with a Mackay-Marg tonometer. 2. There was significant differances between the Mackay-Marg tonometer and Goldmann tonometric values(p<0.005). The corelation coefficent(r) was 0.975, the linear regression was Y = 1.37 + 1.06X. 3. The standard deviation for Mackay-Marg tonometer was greater thandoldmann readings, and it was about 1.37 mmHg higher than Goldmann's. 4. There was significant differances between the Mackay-Marg tonometer and Schiotz tonometric values(p<0.005). The corelation coefficent(r) was 0.938, the linear regression was Y = 0.82X - 0.07.
