To report a method of identifying the lower end of the nasolacrimal duct when more usual methods have failed.
A vitreoretinal fibre-optic light pipe was used to identify the lower end of the nasolacrimal duct in a child with unusual congenital nasolacrimal duct obstruction.
This intraluminal light source enabled easy cut down onto the 'blind' end of the lacrimal drainage apparatus and subsequent intubation with silicone tubing to overcome the obstruction.
This technique may prove useful in the rare cases in which it is not possible to identify the lower end of the nasolacrimal duct with a probe and nasal endoscope alone.
报告一种在更常用方法失败时识别鼻泪管下端的方法。
使用玻璃体视网膜光纤光导管在一名患有特殊先天性鼻泪管阻塞的儿童中识别鼻泪管下端。
这种管腔内光源便于轻松切开至泪道引流装置的“盲”端，并随后用硅胶管插管以克服阻塞。
在仅用探针和鼻内窥镜无法识别鼻泪管下端的罕见情况下，该技术可能有用。
