As a resident in glaucoma clinic, I was often frustrated when I was not able to actually see what the attending physician was describing or when the words "in stereo view, it looks much worse" were used. I often wondered why there was not a textbook that would allow one to appreciate, in stereo, entities such as angle recession or subtle sloping of the nerve. Now, thanks to the works of Campbell and Netland, there is a textbook that achieves these goals. Although the book is not an exhaustive reference on glaucoma, it does contain concise and essential facts on glaucoma and related diseases, in addition to the impressive compilation of stereo photographs. The book includes a portable stereo viewer that is easy to construct. Once assembled, placing the device on the photographs will allow excellent stereoscopic views. The only problem with the viewer is alignment. If the viewer is not directly opposite the light source, shadows can obscure the views. In addition, the viewer, being flexible, can at times twist, causing misalignment. Overall, however, these problems are minimal.
