Insights into the quality and guideline consistency of dry eye disease treatment videos on Chinese short-video platforms.

Purpose: This study aimed to evaluate the quality of dry eye disease (DED) treatment-related short videos on popular Chinese platforms. Methods: To better evaluate the quality of short videos related to DED treatment, the Dry-eye-related Short Videos Standardization Score (DSVSS), a preliminary disease-specific checklist, was developed tailored to DED clinical guidelines. On May 17, 2025, 305 videos (150 from Douyin, 155 from Bilibili) were retrieved using the keyword "dry eye treatment", and their quality and guideline consistency were evaluated with the Global Quality Score (GQS) and the DSVSS checklist. Basic data, including duration, likes, comments, collections, and shares were recorded. Statistical analysis was performed using the Mann-Whitney U test, Kruskal-Wallis H test, and Spearman's rank correlation to assess group differences and correlations. Results: Videos from Douyin were generally shorter but achieved higher user engagement, while videos from Bilibili were longer with lower interaction (both Conclusions: This study effectively identified critical deficiencies of current short-videos on DED treatment, underscoring the necessity for more professional, guideline-based content and stricter platform supervision to improve the quality of online health information.
