A minicomputer-based hardware and software system is described that servomechanically administers two standard clinical tests for strabismus and fusion-the cover and prism tests-to a subject, records the resulting eye movements, and provides a variety of routines for analysis of these results by means of an interactive graphics terminal. The system is characterized by simplicity of operation, requiring only fixation of a stationary target during testing on the subject's part, and only single keystroke commands on the operator's part to either activate the test sequence or call the various graphic-based analysis routines. Eye movement records are segmented by the program into modular test event-related "frames" for ease of manipulation and graphic visualization and analysis, and modularity of the software itself allows convenient modification of or addition to the test sequence or menu of analysis routines. Quantitative specification of eye movement segments of interest includes latency, average velocity, maximum velocity, and maximum acceleration and deceleration.
