温度眼振と回転中眼振の単眼誘導法による分析

抄録

We investigated the difference of eye movement between both eyes during caloric testing by monocular recording of electronystagmography (ENG). We recruited those patients, who had normal or very close to normal peripheral and central vestibular function. We measured slow phase velocities, amplitudes and number of beats during 10 s of culmination phase of each caloric response. The eye of the cold-irrigated side moved significantly stronger than the eye of the non-irrigated side, while a warm irrigation did not induce a significant difference between the eyes of irrigated and non-irrigated sides. We concluded that the inhibitory effect of a cold caloric stimulation is probably transmitted more intensively to the eye of the irrigated side.
