瞳孔测量法

Therefore, we suggested that the method of measuring iris contour by computerised image analysis demonstrated a quantitative description of iris bombe.

因此，我们认为虹膜轮廓计算机图象测量法可定量描述虹膜膨隆程度，为进一步探讨瞳孔阻滞性闭角型青光眼的发病机制及其早期诊断和疗效观察提供了一种有效的方法。

The iris radius of 60 (93 eye) patients with early pupillary block primary angle closure glaucoma was measured with this method, it showed:(1) there was a statistically significant difference in iris radius between the patients with early stage primary pupillary block angle closure glaucoma and the normal subjucts (53 cases 106 eye) with the age matched group (P.01),(2) it is proved with the stepwise discriminatory analysis that the iris radius-the most significant bio-anatomic parameter of the anterior segment is usefull to diagnose early primary pupillary block angle closure glaucoma by stepwise discriminatory analysis.

本研究用此测量法测量了60例93只眼早期原发性瞳孔阻滞性闭角型青光眼的虹膜曲率半径，发现：（1）早期原发性瞳孔阻滞性闭角型青光眼患者的虹膜曲率半径小于同年龄正常人（53例106眼）的虹膜曲率半径，其差异具有显著性统计学意义（P.01）；（2）经多因素逐步判别分析证明本研究所提出的活体眼前节解剖学测量参数——虹膜曲率半径有助于原发性瞳孔阻滞性闭角型青光眼早期诊断。

Methods Forty volunteers with best corrected visual acuity better than 5.0 in the right eye were enrolled in the study. Their ages ranged from 21 years to 32 years; they were all emmetropes or myopes.

对年龄为21~32岁的40例最佳矫正视力≥5.0的近视和正视志愿者分别采用照相机拍摄法、Pupillometer瞳孔测量仪和Rosebaum瞳孔尺三种方法测量瞳孔大小。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
