There is a big need for estimating internal properties of eyeball, since they shoud be closely related to eye diseases, such as detached retina. Based on this background, this paper discusses a new bio-marker expressing the mechanical characteristics of internal eyeball. For (his purpose, we focus on subjects having vitreum surgery in which vitreum of subject is replaced with succedaneum. With the assistance of high speed camera, the eye deformations before and after operation are captured during air-puff impartment. Through the analysis, we found the difference between the behaviors before and after operation, especially the shape of eye ball immediately after the tip of cornea recovers. We discuss why such different behaviors happen and how we can explain the physics.
