The Assessment of YouTube Videos as a Source of Information for Amblyopia Treatment.

PURPOSE To evaluate the efficiency of YouTube videos as a source of information for the treatment of amblyopia. METHODS The authors searched YouTube (Google) using the keywords "amblyopia treatment" and analyzed the first 200 most relevant videos. Videos were classified as useful or misleading by two independent ophthalmologists. Videos were scored on 5-point scales to evaluate global quality, reliability, and comprehensiveness. General characteristics, viewer interactions, and sources of videos were also recorded. RESULTS Eighty-seven of 200 videos were appropriate to be included in the current study. Fifty videos (57.5%) were classified as useful and 37 videos (42.5%) were classified as misleading. General characteristics and viewer interactions were not significantly different between useful and misleading videos (P > .05). The mean Global Quality Score, reliability, and comprehensiveness scores were 3.64 ± 1.1, 3.02 ± 1.0, and 2.74 ± 1.2 in useful videos and 2.03 ± 0.9, 2.08 ± 0.8, and 1.62 ± 0.7 in misleading videos, respectively (P < .05). The data suggested that most of the videos uploaded by university channels or non-profit professionals were useful (79.2%), whereas most of the videos uploaded by medical advertisements or for-profit companies were misleading (59.1%). CONCLUSIONS The results of the current cross-sectional study demonstrated that the number of useful videos for the treatment of amblyopia was higher on YouTube. However, there was still a significant number of misleading videos (42.5%). Therefore, more videos on amblyopia treatment that have sufficient reliability, quality, and comprehensiveness should be uploaded to YouTube. [J Pediatr Ophthalmol Strabismus. 2021;58(5):311-318.].
