ABSTRACT:
The invention contemplates structure for such combinable use of a portable ophthalmoscopy light and a portable stereomicroscope that components are readily convertible to selectively provide ophthalmoscope functions for examination of posterior regions of an eye, and slit-lamp functions for examination of anterior regions of the eye. Knob adjustment of the housing of the ophthalmoscopy light provides selective availability of circular and slit diaphragms, as well as filters, as appropriate to the particular kind of observation to be made.
