非接触眼压计(Non-ContactTonomc-ter)简称NCT,于1972年问世,NCT测定原理是按Imbcrt Fick定理设计的,其公式:P(眼压)=F(压平力)/A(角膜压平面积),仪器由1.气流系统2. NCT的注视红点与角膜顶点必须在一准线的校正系统3.角膜压平监视系统三部份组成。仪器内装有计算机,用以调整汇总各个系统处理获得的数据,最后提供眼压的数值。鉴于国内NCT应用的报道不多,本文将正常人182人364只眼用NCT测定的眼压和用Schi(?)tz眼压计测定的分别加以比较。材料和方法检查对象为来自单位体检的干部和知识分子。视力及眼底检查后,先以NCT测量,
Non-Contact Tonometer (NCT), abbreviated as NCT, came out in 1972. The principle of NCT is designed according to Imbcrt Fick’s theorem. The formula is: P (intraocular pressure) = F (flattening force) / A Pressure flat area), the instrument consists of 1. Airflow system 2. NCT’s attention red dot and corneal apex must be in a line of sight correction system 3. Corneal flattening monitoring system consists of three parts. The instrument is equipped with a computer to adjust the summary of the data obtained by the various system processing, and finally provide the value of intraocular pressure. In view of the domestic NCT application is not much reported, this article will be 182 normal 182 eyes with NCT measured intraocular pressure and Schi (?) Tz tonometer measured separately were compared. Materials and methods to check the object from the unit medical cadres and intellectuals. Visual acuity and fundus examination, first measured by NCT,
