The patients with vitreous floaters were randomly divided into to groups after excluding the possibility of coexisting ocular pathologies potentially confounding visual symptoms or vitreoretinal anatomy. The control group performed conventional oral education. The experimental group conducted multimedia health education activities on the basis of conventional oral education. Their VRQoL (Visual Function Questionnaire-25, VFQ-25) and anxiety status (State-Trait Anxiety Inventory, STAI) were evaluated before education and at the final follow-up. The demographic and clinical characteristics (gender, age, eduaction, duration of vitreous floaters, comorbidities and so on) were collected.
