Abstract
The individual difference in structural eye stiffness might cause the misestimation of the internal eye pressure (IOP: IntraOcular Pressure). In this paper, we measured the eye stiffness for 60 subjects including glaucoma patients with high IOP over 30[mmHg]. The displacement and the contact area are simultaneously measured in the experiment and the experimental results show that some subjects have different deformation even with same IOP estimated by the conventional tonometer.
