Answer

The test should be performed by recording each eye separately, especially if dysconjugate eye movements are suspected. A single-channel saccadic test, normally used to calibrate the equipment, should be interpreted with caution and in the light of findings from clinical examination of conjugate eye movements. Common saccadic abnormalities include dysmetria, slow saccadic velocity, and dysconjugate saccades.
