We investigated the influence of age, gender and refraction on ocular rigidity in Chinese patients. Two groups were studied: 76 healthy young subjects aged between 19–30 years; 70 healthy elderly subjects aged between 57–90 years. The Schiotz tonometer and the Friedenwald paired weight pressure rigidity table were used to determine the ocular rigidity. Age did not significantly affect ocular rigidity. The degree of myopia was poorly correlated with ocular rigidity (r= 0.109). The mean value for all healthy subjects was 0.0156 (sd 0.0065). This is lower than previously reported values which range from 0.0184 to 0.0263.
