Recent reviews describing the various tests for malingering have appeared in the literature.1 It is not my purpose to duplicate this work ; rather, I wish to present the following material : A workable classification of ocular malingering in which the more useful special tests are placed where they can be used to greatest advantage. A correlation table to serve as a guide to the ophthalmologist in evaluating exaggeration of poor uncorrected vision. A statistical analysis of the true monocular amblyopias to show the wide range of corrected vision.

OCULAR MALINGERING Incidence in Army Induction Examinations. —Fortunately, the incidence of ocular malingering in routine Army induction examinations is low. Although no accurate statistics are available, it is safe to put the figure between 0.5 and 3 per cent. This seems negligible, but it means that
