摘要

为解决青光眼患者的24h眼压连续测量问题

提出了一种眼压磁力连续测量原理

采用2个永久磁铁同极靠近产生的排斥力对眼球施加压力

通过求解排斥力—距离曲线上波动点处的压力或波动点后的斜率计算得到眼压值。给出了测量系统结构及其磁排斥力仿真计算结果

对猪眼的实验结果显示

眼内压的大小和排斥力—距离曲线波动点处的压力值存在对应关系

该方法可以作为眼压24h连续测量的有效途径。

Abstract

To solve the problem of the 24h continuous measurements of intraocular pressure（IOP） of the glaucoma patients

a new principle and method based on magnetic force is presented.The pressure to eyeball is produced using the repulsive force generated by two permanent magnets when they are closed by facing the same magnetic pole.The IOP is obtained by calculating the pressure of the fluctuating dot or the rake ratio after the fluctuating dot of the repulsive force-distance curve.The structure of the detecting system and the result of the magnetic simulation of two permanent magnets are given.The results of the pig eye experiments indicate that IOP is relative to the pressure of the fluctuating dot of the repulsive force-distance curve.As a result

the principle and method proposed is feasible for the 24h continuous measurement of intraocular pressure.
