Ocular Motility Recording and Nystagmus

AbstractThe accurate recording of eye movements for the study of ocular motor mechanisms (normal or abnormal) or for the diagnosis and treatment of ocular motor disorders requires a reliable, easy‐to‐use recording system; proper monocular calibration and linearization paradigms; and, in subjects with nystagmus or other ocular motor oscillations, knowledge of the foveation portions of the eye‐movement waveforms. In this chapter, the different types of eye movements generated by the ocular motor system, the advantages and disadvantages of commonly used recording systems, the requirements for accurate calibration of those systems, and the use of eye‐movement recordings in basic research, including clinical settings, are described.This work was supported in part by the Office of Research and Development, Medical Research Service, Department of Veterans Affairs.
