AIM: To investigate the cause and treatment of abnormal blinking in 225 children.

METHODS: A retrospective analysis was performed on the causes, examination results, treatment methods and efficacy of abnormal blinking in 225 children.

RESULTS: Among 225 children, 156 cases(69.3%)had corneal or conjunctival diseases, of which 68 cases(30.2%)were diagnosed with allergic conjunctivitis and 88 cases(39.1%)with other corneal or conjunctival diseases, 38 cases(16.9%)were found with eyelid disease, 65 cases(28.9%)with ametropia, 56 cases(24.9%)with dry eye, and 108 cases(48%)with video terminal syndrome. After 1wk to 2mo of treatment for the underlying causes, 175 cases were cured and 35 cases were improved, with no improvement observed in 15 cases.

CONCLUSION: The cause of abnormal blinking in children is relatively complex, which is closely related to allergic conjunctivitis, video terminal syndrome, dry eye and ametropia. It should be considered comprehensively in clinical practice and treatment should be given targeting different causes.
