角膜感觉受三叉神经第一分枝支配,是人体感觉最敏锐的部位。角膜处于面部前端易受物理及化学性等因素的危害,角膜知觉在某些职业病的诊断中具有显著意义。但以往仅用棉花絮尖端触压角膜作定性的检查,但亦有仪器的触压法,我国少用。我们需要有一种定量的得心应手的角膜知觉检查仪。我国包寅嘉氏在BoBerg—Ans 研究的基础上研制的角膜知觉测定仪。其对马鬃的物理性等研究,把角膜知觉从定性改革为定量检查,对眼科界具有一定的贡献,但测定仪后面拖一金属引线在应用时尤其 The cornea is dominated by the first branch of the trigeminal nerve and is the most sensitive part of the human body. Cornea at the front of the face susceptible to physical and chemical hazards, corneal sensation in the diagnosis of certain occupational diseases have significant significance. But in the past only the tip of cotton floss touch the cornea for qualitative examination, but there are instruments of touch-pressure method, less used in our country. We need a quantitative, handy corneal awareness tester. China’s package Yoshitaka BoBerg-Ans study developed on the basis of corneal perception tester. The physical study of the horse’s mane, the corneal perception from quantitative to quantitative examination of the reform, the ophthalmic community has made some contribution, but the tester dragged a metal lead in the application, especially
