Kinetic electro-oculography: aims - disadvantages and limitations.

A recording technique is essential in the study of ocular movements. At present, numerous mechanical, optical and electrical methods are under review. Kinetic electro-oculography is at the moment the only available technique which fulfills most clinical requirements. However, it is a delicate method, subject to numerous hazards; the sources of errors are manifold. With electro-oculography, we can only expect a qualitative and comparative assessment of horizontal movements. Displacements along the oblique axes cannot be studied.
