Abstract: Methods and devices for rapid, self-administered, and adaptive testing of a wide variety of visual and neurological impairments are based on graphical presentation to a subject of visual stimuli of varying intensity. Psychometric functions are used to determine the subjects sensitivity to selected stimuli. Diagnosis of ophthalmic, optometric, and/or neurologic conditions is achieved from the subjects stimulus sensitivity pattern.

Abstract: Testing methods for evaluating visual and neurological functions of a human or animal subject that involve conscious perception. The tests include a training phase, a practice phase, and a visual rivalry phase for detecting binocular rivalry or multistate competition. The design of the testing methods offers simple, rapidly administered, nonverbal visual testing with high time resolution and access to changing conscious perceptual states of the test subject. The methods also make possible the collection of a large amount of data in a short time for analysis of the subjects visual function and brain function, and can be used in the diagnosis of many medical conditions.
