A simple teaching pointer has been devised for use with the indirect ophthalmoscope. A bristle is attached to a thimble that is placed on the thumb of the hand not holding the indirect lens. It can be used with or without scleral depression to define specific retinal lesions.
已设计出一种与间接检眼镜配合使用的简易示教指针。一根刷毛附着在一个顶针上，该顶针放置在未握持间接检眼镜的手的拇指上。它可在有或没有巩膜压迫的情况下使用，以明确特定的视网膜病变。
