Abstract

Eye movements were recorded by electronystagmography using silver plate electrodes and search coils, and they were analyzed by a microcomputer.<BR>Eye movements recorded by scleral search coils are noise-free and very stable. Especially, vertical eye movements-pursuit or saccades-are recorded precisely and are not affected by blinking.<BR>Eye movements can be recorded with visual angle of up to 30 degrees, but 20°is better for routine examinations. It is very easy to obtain DC-recording of monocular movements by search coils. The recording using search coils is not affected by EMG or by sweat. It is possible to record eye movements with search coils even in patients who have no corneoretinal potentials. However, the movements during eye closure should be carefully considered when search coils are used.
