Assessment of Quality and Trustworthiness of Glaucoma Videos on Douyin and Bilibili
Overview
This cross-sectional study evaluated the quality and reliability of the top 100 glaucoma-related videos on Douyin and Bilibili, two major Chinese video platforms. Using validated tools, the study identified significant variability in content quality and highlighted concerns about misinformation and incomplete patient education.
Background
Glaucoma is a leading cause of irreversible blindness worldwide, with a growing prevalence due to aging populations. Early detection and sustained management are critical to prevent vision loss. With increasing public reliance on online video platforms like Douyin and Bilibili for health information, assessing the accuracy and trustworthiness of glaucoma-related content is essential. Prior studies have shown quality issues in ophthalmic videos on these platforms, but glaucoma-specific evaluations remain limited.
Data Highlights
The study retrieved the top 100 glaucoma-related videos from each platform using new user accounts to minimize algorithm bias. Videos were categorized by source, presentation form, and content type. Key metrics such as uploader identity, video duration, engagement (likes, comments, shares), and publication date were documented. Videos from professional and nonprofessional sources were analyzed separately. Quality was assessed using Global Quality Score (GQS), mDISCERN, JAMA benchmarks, and PEMAT-A/V tools.
Key Findings
Glaucoma videos on Douyin and Bilibili showed wide variability in quality and reliability, with many lacking comprehensive and accurate information.
Professional individuals and institutions generally produced higher-quality content compared to nonprofessional sources.
Videos often failed to adequately address critical glaucoma education points such as early detection, symptom recognition, and long-term management adherence.
The audiovisual format enhanced understandability but did not guarantee actionability or trustworthy content.
Engagement metrics did not consistently correlate with video quality, indicating popular videos are not always reliable.
The absence of peer review and regulation on these platforms contributes to the dissemination of misinformation.
Clinical Implications
Clinicians should be aware that patients may access glaucoma information from online video platforms with variable quality. Healthcare providers should guide patients towards verified, professional sources and consider integrating reliable digital content into patient education. Efforts to improve the quality and regulation of glaucoma-related videos on popular platforms are needed to support effective public health communication.
Conclusion
This study highlights significant quality and trustworthiness concerns in glaucoma-related videos on Douyin and Bilibili, underscoring the need for improved content standards and patient guidance. Enhancing the reliability of online glaucoma information is critical to support early detection and effective disease management.
