简要总结
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.
详细描述
Patients inclusion criteria: 1)Patients with VF visited the Department of Ophthalmology, the third affiliated hospital of Nanjing Medical University between December 2023 and April 2025; 2) Endogenously derived subjective floaters confirmed by comprehensive ophthalmic examination including slit-lamp biomicroscopy, dilated fundoscopy, optical coherence tomography (OCT) and so on; 3) Willing to participate in the multimedia health education program and complete validated questionnaires, with written informed consent obtained.
exclusion criteria:
1)Secondary VF requiring surgical intervention (e.g., vitreous hemorrhage, retinal breaks, or uveitis); 2) Coexisting ocular pathologies potentially confounding visual symptoms or vitreoretinal anatomy (e.g., diabetic retinopathy, retinal vascular occlusion, epiretinal membrane, or vitreomacular traction syndrome); 3) History of vitreoretinal surgery (PPV or laser procedures); 4) Refusal or inability to complete study protocols.
Intervention:
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). Multimedia presentation was made through pictures, texts, sounds, and videos. The simple and easy-to-understand language were used to make population easy to accept.

结局指标
主要结局
State-Trait Anxiety Inventory scores
时间窗: before the intervention, 3months after the intervention
This questionnaire comprise two 20-item subscales state anxity and trait anxiety: STAI-state evaluating transient emotional responses ("how you feel right now") and STAI-trait measuring stable anxiety predisposition ("how you generally feel"). The scores for each test ranged from 20 to 80 points, with higher scores indicating higher anxiety.Scoring followed Spielberger's manualized criteria. According to the Spielberger manual, STAI-state and STAI-trait are categorized as follows: mild anxiety ranges from 20 to 39, moderate anxiety from 40 to 59, and high anxiety from 60 to 80.
次要结局
- Visual Function Quality 25 scores.(before the intervention, 3months after the intervention)
