Quality and Reliability of Upper Eyelid Ptosis-Related Short Videos on Bilibili and TikTok: A Cross-Sectional Study

BACKGROUND: Upper eyelid ptosis is a commonly encountered ophthalmological disease that reduces both visual performance and quality of life. Short-video platforms have become popular sources for health information. The objective of this study was to evaluate the reliability, accuracy, and content features of short-form videos addressing upper eyelid ptosis available on social media platforms TikTok and Bilibili. METHODS: We searched "upper eyelid ptosis" and collected the top 150 videos from each platform using default rankings. Assessment utilized mDISCERN, Global Quality Score (GQS), and Journal of the American Medical Association (JAMA) benchmark for video quality evaluation. We assembled and examined basic video properties, content scope, and user engagement metrics. Platform and uploader category comparisons addressed general characteristics and video quality parameters. RESULTS: Analysis included 214 videos. Median video length was 63.50 seconds (IQR: 43.75-104.75). Most videos covered etiology (74.8%), clinical manifestations (84.6%), diagnosis (79.4%), and treatment (81.8%). However, epidemiology, prevention, and prognosis were rarely discussed. Video quality proved inadequate: median GQS reached 3.00 (IQR: 2.00-3.00), mDISCERN scored 2.00 (IQR: 1.00-4.00), and JAMA achieved 2.00 (IQR: 2.00-3.00). Content from professional healthcare providers attained superior quality (median GQS and mDISCERN = 3.00, P<0.001), whereas individual users generated the highest engagement levels. User interaction metrics showed no significant association with video quality scores. CONCLUSIONS: Overall quality of ptosis-related short videos on TikTok and Bilibili remained inadequate, displaying systematic deficiencies in content organization. Professional healthcare provider videos showed enhanced quality but reduced engagement rates. Our findings also emphasize the need to encourage healthcare professionals to become more involved in health-related social media dissemination to enhance the effectiveness of reliable medical content sharing on short-video platforms.
