Binocular Vision and the Modern Treatment of Squint.

This booklet is divided into seven chapters, covering binocular vision, binocular balance, suspension of vision, amblyopia, the refractor and dynamic retinoscope, dynamic retinoscopy in cases of squint, and orthoptic training. The majority of the illustrations are of some commercial firm's instruments, guaranteed to cure squint in six lessons in spare hours. The text tends to indicate a rather rudimentary and half-baked knowledge and abounds with misstatements, such as "to cover the non-squinting eye with a disc has not had very satisfactory results.... It is better, if this form of treatment is adopted, to cover the amblyopic eye when the sound eye is in use." Despite emphasis laid on refraction there is no mention made of the use of cycloplegics, and from the high sounding terms used to cover the lack of use of cycloplegia one would suspect the author of being an optometrist either in reality or in spirit.
