Visually stimulated saccadic eye movements in patients treated with lithium.

Saccadic eye movements were stimulated with the aid of 11 light spot stimuli, 10 of which were arranged at 3 degrees, 6 degrees, 9 degrees, 12 degrees, and 15 degrees to the left and right of the central stimulus. The parameters average and maximal eye movement velocity and latency were precisely investigated. 19 patients averaging 6.6 years on lithium prophylaxis were compared with 23 healthy controls. Significant differences between the two groups could not be found at this level of function.
