Abstract
We examined the tear drainage system of twenty-fiv normal volunteers by scintillography with Technetium Tc 99m (Pertechnetate). We photographed the changes occurring in the lacrimal sac and nasolacrimal duct during closure and opening of the eyelids. Our findings support Jones' views of normal tear drainage. The tracer was concentrated in the lacrimal sac while the lids were closed for 3 minutes and descended into the nasolacrimal duct as soon as they opened.
摘要
我们通过用锝 Tc 99m（高锝酸盐）进行闪烁造影检查了25名正常志愿者的泪液引流系统。我们拍摄了眼睑闭合和张开过程中泪囊和鼻泪管发生的变化。我们的研究结果支持琼斯关于正常泪液引流的观点。当眼睑闭合3分钟时，示踪剂集中在泪囊中，一旦眼睑张开，示踪剂就会下降到鼻泪管中。
