新型角膜缘环杆眼内异物定位器的应用

Use of new limbal ring-rod for radiological localisation of ocular foreign body.

本文应用新型三维角膜缘环一杆定位器代替常规的异物定位圈,作眼球正侧位X线摄片.并配合几何比例图,作出异物定位,达到简单、便宜,而又更准确的异物定位.本文还介绍了定位器的制作和几何测量等方法,供参考.

We use the new limbal ring-rod instead of routine limbal ring to take frontal and lateral views x-raying also make the proportional geometric drawing to provide a simple inexpensive and fairly accurate measure for the radiological of ocular foreign bodies. We intro-d uce the methed of making the limbal ring-rod and the methed of measuring geometric drawing for reference.
