Ophthalmoscopy, Retinoscopy and Refraction; with a New Chapter on Orthoptics.

The present edition of this volume has a new chapter of thirty pages with a bibliography of sixty-one references on the orthoptic treatment of strabismus. The method of Cantonnet is described at length, and there are outlines of the procedures used by Dobson, Peter, Guibor, Gifford and Cameron. Statistics are given as to the results obtained by various workers. The remainder of the volume is similar to the earlier editions. One notes a great deal of unnecessary repetition throughout the text. Also, the treatment recommended for many of the pathologic conditions described in the sections on diseases of the retina, choroid and optic nerve is too briefly described. In the reviewer's opinion, therapy should have been discussed more fully or should not have been considered in the volume.
