Diameters of the pupils were measured from photographs and by an infra-red television system. 123 cases of Meniere's disease (pathological group) and 71 normal subjects (normal group) were studied.
The appearance rate of anisocoria was 22 to 29 per cent in the pathological group and 4.5 to 14 per cent in the normal group. The difference between the two groups was more significant following the cold pressor test or application of neosynephrine solution to the eye.
Several possible causes of the findings were considered, and the correlation between the course of the attacks and the variations in the degree of anisocoria was studied. The results were used as a guide in classification, aniticipating prognosis and for reconsideration of the basic principles in the treatment of this disease.
It was interesting to note that patients with Meniere's disease or migraine both often show anisocoria or abnormal pupillary reactions which may be ascribed to autonomic imbalances in the head and neck region.
