【摘要】 用自制睑外眼球压迫器压迫眼球4分钟,并用非接触眼压计测量眼压,共对162只正常眼进行了检查。结果平均下降率为32.03％,正常下降范围为32.03％±1.96×5.5％=32.03±10.78％,属正态分布。眼球压迫前后对比具有明显显著性差异。说明本法可应用于临床,作为对慢性单纯性青光眼的诊断方法之一。此法简单、安全、准确,压迫器容易制作。更多还原

【Abstract】 We have made extrapalpebral bulbar compression tests on 160 normal eyes in 81 patients using a self-designed extrapalpebral compressor. The intraocular pressure was examined by a noncontact tonometer （N C T） .The averages of the intraocular pressure before and after compression were 11.4 turn Hg and 3.46 mm Hg respectively （p<0.01） . Therefore, the difference between the intraocular pressure before and after compression was marked. The formula （P₀-P_t）/（p₀）×100% was used to calculate the rate of drop in the intraocular pressure. The average of the intraocular pressure drop was 32.03%. The standard deviation was 5.5%. The range of dropping was 32.3±10.78%. As this method is applied without direct contact to the cornea, it is safe and accurate. we suggest that this method may be used clinically for the detection of open-angle glaucoma.更多还原
