[Pupillary reactions in neurotic disorders].

For the differentiation of neurotic disorders, the indices of pupilary reactions and hippus were studied. The study was performed with the aid of a pupillograph. A comparison of the pupillographic data in patients with borderline neurotic disorders of the 3 main groups (asthenic, obsessive-phobic and hysterical), demonstrated statistically significant differences in the control group and within the group with different forms of neurotic disorders. The quantitive and informative characteristics of the pupilary reactions and some regular tendencies in the characteristic of the hippus may help in the solution of one of the main problems of borderline psychiatry, an improved diagnosis.
