Effectiveness of Multimedia Health Education to Reduce Anxiety in Patients With Vitreous Floaters

Multimedia health education was designed as an intervention. This intervention was administered by a single vitreoretinal specialist with over a decade of clinical experience. This standardized protocol comprised a 30-minute didactic session utilizing power point presentations (PPT), systematically covering: 1) Etiopathogenesis: Molecular mechanisms of vitreous syneresis and collagen aggregation; 2) Symptomatology: Characteristic visual phenomena and differential diagnosis; 3) Therapeutic modalities: Evidence hierarchy from observation to vitrectomy (including Nd:YAG laser efficacy controversies); 4) Follow-up necessity: Red flag symptoms warranting urgent re-evaluation (sudden floaters with photopsia)
