The ophthalmograph is a portable camera that records the movements of both eyes while they are engaged in reading. The record thus obtained is supposed to reveal important data on the reading habits of the individual and also on the binocular coordination. There is little information available in the ophthalmic literature concerning the reliability and the validity of the reading graph. Since the ophthalmologist should be concerned with everything connected with vision, it was decided to photograph a series of patients in an attempt to evaluate the instrument. The American Optical Company discontinued production of the ophthalmograph during the last war because of its high cost as compared with the small number that they sold. It is possible, therefore, that many ophthalmologists are not aware of its use or even of its existence.
The instrument has small lights which can be focused on the eyes. These are reflected by the
