Objective: To compare the efficacy of two methods of psychological treatment of hysterical visual impairment. Methods: Patients with hysterical visual impairment were prospective divided into an observation group (20 cases) and a control group (12 cases). The observation group was treated by wearing of plano glasses, and the control group was treated by stimulation of the temporal skin with lacrimal dilator.The curative effects and complications of the two groups were compared by using t test and chi-square test.Results: The visual acuity of the control group increased 0.78±0.21 (t=18.32, P<0.001 compared to the pretreatment value). The visual acuity of the observation group increased by 0.82±0.21 (t=24.84, P<0.001 compared to the pretreatment value). The difference of increasement in visudal actity between the two groups was not statistically significant (t=0.75, P=0.45). The improvement rate of visual field was 83%in the control group and 89% in the observation group, there was no significant difference between the two groups (χ2=1.50, P=0.30). Two cases in the control group with complications (skin trauma), and none occurred in the observation group (χ2=11.89, P=0.002). Conclusions: Treatment of hysterical vision by spectacle wearing and by skin stimulation similarly improved visual acuity. While skin stimulation caused some complications, there were no adverse reactions to wearing glasses.
