Abstract
- The Korean 218 normal eyes, 74 myopic eyes and 42 glaucomatous eyes were examined. The intraocular pressure were measured by Goldmann applanation tonometer and Schiotz indentation tonometer using the 5.5 gm plunger load successively. The occular rigidity was estimated from Friedenwald 1955 nomogram. In normal eyes, the average coefficient of ocular rigidity was 0.0221 (standard deviation 0.0058, range 0.0032~0.0370). There was a statistically significant increase with age. It was higher in males than in females. But there was no statistically significant difference between sex. In myopic eyes. the average coefficient of ocular rigidity was 0.0189. There was an increase with refractive power but it was not statistically significant. In glaucomatous eyes. the average coefficient of ocular rigidity was 0.0181 in the medication-treated group and 0.0163 in the operated group. They were significantly lower than in normal eyes statistically. But there was no significant differance between medication-treated and operated groups.
