This well-printed and illustrated manual, written by an acknowledged expert in the field, is a concise, literate summation of current knowledge of the anatomy, instrumentation, and disorders of the angle of the ocular anterior chamber. Its unique feature is the inclusion of 56 full-color stereophotographs and a collapsible viewing device. My only adverse criticism is that the viewer is obviously fragile and awkward to use. It can be easily replaced, however, with a standard, nonfolding instrument. This manual provides an excellent introduction to clinical gonioscopy.
