The top 200 videos under \u201ccomprehensive ranking\u201d were screened, and 196 videos meeting the eligibility criteria were ultimately included. Content integrity was evaluated following the American Academy of Ophthalmology guidelines and the Goobie framework. Video quality was assessed using the DISCERN instrument and the PEMAT-A\/V tool. Statistical analyses were performed in IBM SPSS Statistics 27.0, with inter-rater reliability measured by the intraclass correlation coefficient. Differences among groups and associations between variables were examined using ANOVA and correlation analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The overall quality of the included videos was moderate, with a median DISCERN tool score of 48.00 and a median Overall quality score of 3.00. The Understandability score was relatively high (median 84.62%), whereas the Actionability score was lower (median 75.00%). Videos uploaded by the Non-Profit group showed the highest quality (mean DISCERN tool score 59.13 \u00b1 2.50), followed by the Medical group. The Non-Medical and For-Profit groups demonstrated the lowest quality, with statistically significant differences among groups (\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt; 0.05).

Information quality varied by uploader source, with non-profit organizations and medical professionals providing most high-quality content. Higher-quality videos tended to receive greater user engagement, suggesting that platform algorithms may preferentially spread better educational material. These findings provide empirical support for improving science communication on this disease and strengthening information quality management on digital platforms.<\/jats:p>\n
