Emotional factors in strabismus.

Emotional disturbance may cause strabismus which disappears when the disturbance is relieved. It is frequently the cause of a deterioration in the control of an esotropia particularly that associated with a high AC/A ratio. Two cases are reported. In the first, a concomitant esotropia was present in an adult with paranoid schizophrenia. This resolved completely after psychiatric treatment. The second case resembled a lateral rectus palsy. This also resolved on psychiatric treatment.
