眼压是判断眼睛是否患有青光眼的重要指标。传统的眼压测量只有在假设所有受试者具有相同的眼硬度的情况下才能为我们提供有意义的数据。然而，我们以前的工作表明，这个假设是不成立的。本作品是扩展版本。通过结合5000[fps]的高速摄像机和空气喷吹供应系统，可以相对于时间精确地跟踪眼表面。我们引入了一个新的参数，这是在一个预定的作用力的位移。我们发现，该参数可以强烈地强调个体眼刚度的特征，并与测量的外部眼压（IOP）保持高度相关性。
The eye pressure is an important index for judging whether an eye suffers from glaucoma or not. Conventional eye pressure measurements provide us with meaningful data only under the assumption that all the subjects have the same eye stiffness. Our former work, however, says that the assumption is not valid. This work is an extended version. By combining both a high speed camera with 5000[fps] and an air puff supply system, the eye surface can be precisely tracked with respect to time. We introduce a new parameter, which is the displacement at a predetermined applied force. We found that the parameter can strongly emphasize the characteristic of the individual eye stiffness and keeps a high correlation with the measured external eye pressure, so called IOP (intraocular pressure).
