Objective: To analyze the causes of hysterical visual impairment in children, and to compare the efficacy of two treatments of trial frame and artificial tears administration. Methods: A total of 36 children with sudden hysterical visual impairment admitted to Shenzhen Children’s Hospital from October 2013 to October 2020 were enrolled in our study, including 16 males and 20 females. They were randomly divided into trial frame group and artificial tears group. Both groups were supplemented with verbal suggestion during the treatment. The primary effective rates of the two groups were compared by SPSS 17.0 Fisher’s exact test. The causes of hysterical visual impairment in children were analyzed, and the main points of specific diagnostic tests and treatments were summarized. Results: The primary effective rate of the trial frame group and the artificial tears group were 94.4% and 83.3% respectively.Thedifference was statistically significant (P<0.05). In this study, therewere 20 cases (55.6%) related to study pressure, including decline in academic performance, evasion of exams, reprimand by parents or teachers, and even corporal punishment. There were 13 cases (36.1%) caused by family accidents, and parents’ divorce was the main reason. Leftover children unwilling to return hometown, classmate disputes, campus bullying and trauma were other reasons. Conclusion: Trialframe is more effective than artificial tears therapy in improving primary effective rate of hysterical visual impairment. Study pressure, family accident are the most common causes of hysterical visual impairment
