测量眼压是眼科临床工作中的一项基本检查。目前,国内外常用的眼压计有Schiotz眼压计、眼压计、Goldmann眼压计。它们都有很大的实用价值,但也存在有不足之处。如Schiotz眼压计本身重量大,对球壁硬度影响显著,Goldmann眼压计必须配合裂隙灯使用,不适合农村牧区广泛应用。我们于78年以来,围绕着以上三种眼压计的各自特点和缺陷,设计制做了一种新型的光学压平眼压计。一、眼压计的工作原理: 在角膜被压平时,角膜上的荧光素被挤压到压平面的周边。在蓝光的投射下形
Measuring intraocular pressure is a basic examination in clinical ophthalmology. At present, there are Schiotz tonometer, tonometer, Goldmann tonometer which are commonly used at home and abroad. They all have great practical value, but there are also some shortcomings. Such as the Schiotz tonometer itself, the weight of a significant impact on the hardness of the ball wall, Goldmann tonometer must be used with the slit lamp, not suitable for rural areas pastoral areas. Since 78 years ago, we have designed and manufactured a new type of optical pressure tonometer based on the characteristics and defects of the above three kinds of tonometer. First, the working principle of tonometer: When the cornea is flattened, the fluorescein on the cornea is squeezed to the periphery of the pressure plane. Under the projection of blue light
