Stiffness Sensing of Human Eye

Abstract

This paper challenges the stiffness sensing of a human eye. Eye pressure is an important index for judging whether an eye suffers from glaucoma or not. However, eye pressure measurements provide us with meaningful data only under the assumption that every subject has an equal stiffness of his or her eye. The stiffness sensing of a human eye provides the answer on whether this assumption is correct or not. For this purpose, we developed a stiffness sensing system composed of both an air-jet supply and a high speed camera that has 5, 000[fps]. By using the system, we executed experiments and found that each subject has his or her individual eye stiffness. This suggests that the stiffness measurement is important for the precise diagnosis of glaucoma.
