Abstract

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).
利用高速摄像机实现人眼动态感知
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的眼睛硬度相同的情况下才能为我们提供有意义的数据。然而,我们之前的研究表明,这个假设是不成立的。这项工作是一个扩展版本。通过结合5000[fps]的高速摄像机和气泵供应系统,可以根据时间精确跟踪眼睛表面。我们引入一个新的参数,它是在一个预定的外力作用下的位移。我们发现,该参数能强烈地强调个体眼刚度的特征,并与测量的眼外压(即IOP)保持高度相关。
