BackgroundSocial media as well as YouTube are widely used to gain information on medical conditions. We aimed to assess and evaluate the quality and reliability of YouTube videos on ocular allergies and determine whether they are a trustworthy source of information.Research design and methodsThe first 60 videos from the search terms 'allergic conjunctivitis', 'atopic conjunctivitis', 'allergic conjunctivitis symptoms', and 'allergic conjunctivitis eye drops' were analyzed using modified DISCERN, Global Quality Score, Journal of the American Medical Association scores, and Health on the Net Code criteria. The total number of views, view ratio, likes, comments, and duration were recorded, and videos were evaluated as useful, non-useful, and misleading.ResultsThe average mDISCERN score for the videos was 3.25 +/- 0.76 (moderate), the average JAMA score was 2.76 +/- 0.64 (intermediate), the average GQS score was 3.13 +/- 0.8 (intermediate), and the average HONcode score was 7.8 +/- 2.6 (intermediate). The most common video source was health professionals (61.9%).ConclusionsVideos on allergic conjunctivitis while having reliable publishers are of moderate quality. Quality regulation of content uploaded on allergic conjunctivitis is needed. Health professionals should try to improve video content and provide more information on the treatment of allergic conjunctivitis.
