“…7 In studies evaluating the quality of YouTube videos that are related with refractive surgery, soft contact lenses, multifocal lenses and keratoplasty, the quality of these videos was found to be poor or fair. 9,11,21,22 Similar results were obtained in our study. Although some YouTubes videos contain useful information for uveitis patients, most videos have poor quality, reliability and include inadequate information.…”

Background: The aim of this study was to analyze the quality of videos on YouTube as educational resources about uveitis.Methods: An online YouTube search was performed using the keyword ''uveitis''. Total view counts, duration of videos, publishing dates, likes and dislikes, numbers of comments, and source of videos were recorded. Educational quality and accuracy of the video content were evaluated using the DISCERN score, Global Quality Score (GQS), Journal of the American Medical Association (JAMA) score. Video popularity was also evaluated using the video power index (VPI) score. All videos were classi ed according to publishers and types of categories.Results: From among the 200 videos analyzed, 94 were included. The mean DISCERN score was 38.5 ± 13.2 (poor), the mean JAMA score was 1.8 ± 0.6 (fair), and the GQS was 2.5 ± 0.9 (fair). There were positive correlations between the three checklist (p < .001). VPI was not correlated with each score (p >.05). The most common upload sources were ophthalmologist (24.4%) and YouTube channel (20.2%).Regarding content, 47 videos (50%) medical education, 26 videos (27.6%) patient education, 16 videos (17%) patient experience, 5 videos (5.3%) surgical procedures in patient with uveitis. While the most popular videos were uploaded by doctors other than ophthalmologists, the videos uploaded by academic institutions and associations were found to be higher educational quality and reliability scores.Conclusions: Uveitis videos on YouTube are poor quality and reliability and are not adequately educational for patients. Therefore, the physicians must be aware of the limitations of YouTube and ensure the ow of correct medical information to patients.

“…However, the number of views and daily views can be easily manipulated by video uploaders. It has been suggested that the correlation analysis between daily viewing rates and likes, dislikes and comments can provide us with more objective data to guide us [30]. In our study, we found that there was a strong positive correlation between daily viewing rates and likes, dislikes and comments, supporting this view.…”

Purpose To evaluate the reliability, quality and effectiveness of YouTube videos adressing treatment of keratoconus. Methods This is a retrospective, cross-sectional and register-based study. A YouTube search was performed using the keyword treatment of keratoconus and the first 100 videos that came out were included in the study. The numbers of views, likes, dislikes, comments, daily viewing rate (number of views per day), uploaded source (physicians, public or private institution, health channel or patients), country of origin, video type (patient experience, scholarly information), and describe treatment technique (contact lens, corneal crosslinking, intrastromal corneal ring, topography guided-photorefractive keratectomy, keratoplasty) were evaluated for all videos. They were also evaluated regarding their DISCERN, Journal of the American Medical Association (JAMA), global quality (GQS) and usefulness scores by two independent ophthalmologists. Results Of the top 100 videos, 83 videos met the criteria. The mean DISCERN, JAMA, GQS and usefulness score were 42.92 ± 18.14, 2.7 ± 0.73,3.07 ± 1.25 and 2.99 ± 1.44, respectively. Of the 83 videos, 35(42.2%) had been uploaded by physicians, 19(22.9%) by patients, 15(18.1%) by health channel and 14(16.9%) by institutions/private health institutions. In the correlation analysis, the four scoring systems showed a statistically significant and strong positive correlation with each other (p < 0.001). In addition, viewing rate DISCERN, GQS, usefulness scores, number of likes, dislikes and comments showed a statistically significant positive correlation. Conclusion The content of YouTube videos regarding treatment of keratoconus is of generally good quality and is educational for patients. Increasing the number of videos uploaded by healthcare professionals will increase the quality, reliability and informative features of the videos.

“…Some studies are stating that quality videos are less popular, some studies report that quality does not make a difference in user interactions, or some studies indicate a significant strong positive correlation between quality videos and user interactions. 9,[18][19][20][21][22][23] In this study, a significant positive correlation was found between video duration and user interactions parameters and all scoring systems. Although this positive correlation in dislike and daily dislike parameters was initially surprising, the positive relationship between the video quality and the number of views shows us that quality videos are watched more.…”

Purpose:The aim of this study was to evaluate the demographic features, quality, and reliability of YouTube videos addressing dry eye disease (DED).Methods:The term “dry eye disease” has been searched on YouTube. The first 500 videos that emerged using the defined search term were evaluated. Duplicated-split videos, videos shorter than 60 seconds, videos with a language other than English or videos with an unintelligible English accent, and videos unrelated to DED were excluded. Video uploaders, types, origins, durations, and viewer interactions of the videos were noted. DISCERN, the Global Quality Score, and the Video Quality Score (created by the authors) were used to evaluate the video quality.Results:Of the 500 videos, 262 videos were excluded, and the remaining 238 videos were evaluated. Videos were of moderate quality on all 3 scoring systems. The medical institute and academic society videos had the highest quality (P < 0.05). The quality of videos uploaded by physicians was significantly lower than medical institute and academic society videos and was higher than the others (P < 0.05). User interactions and video duration were weakly positively correlated with the video quality (P < 0.05).Conclusions:Among YouTube videos on DED, only a minority are of good or excellent quality. Videos uploaded by medical institutes or academic societies scored higher in quality than those uploaded by physicians, which, in turn, scored higher than those uploaded by all others. User interactions were weakly correlated with quality values, suggesting user interactions are not good indicators of the quality of YouTube videos on DED.
