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
