PURPOSE To evaluate the reliability, quality and effectiveness of YouTube videos addressing 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 described treatment technique (contact lens, corneal cross-linking, 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 score (GQS) and usefulness score 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.

评估 YouTube 上圆锥角膜治疗信息的质量。

目的 评估治疗圆锥角膜的 YouTube 视频的可靠性、质量和有效性。方法 这是一项回顾性、横断面和基于注册的研究。使用 keratoconus 的关键字处理进行了 YouTube 搜索，最初出现的 100 个视频被包括在研究中。观看次数、喜欢、不喜欢、评论、每日观看率（每天的观看次数）、上传来源（医生、公共或私人机构、健康频道或患者）、原产国、视频类型（患者体验、学术信息)，并对所有视频进行了描述的治疗技术（隐形眼镜、角膜交联、基质角膜环、地形引导的屈光角膜切除术、角膜移植术）的评估。他们还接受了关于他们的 DISCERN 的评估，美国医学协会杂志 (JAMA)、全球质量评分 (GQS) 和两位独立眼科医生的有用性评分。结果 在前 100 个视频中，有 83 个视频符合标准。平均 DISCERN、JAMA、GQS 和有用性得分分别为 42.92 ± 18.14、2.7 ± 0.73、3.07 ± 1.25 和 2.99 ± 1.44。在83个视频中，35个（42.2%）由医生上传，19个（22.9%）由患者上传，15个（18.1%）由健康渠道上传，14个（16.9%）由机构/私人卫生机构上传。在相关性分析中，四个评分系统之间显示出统计学上显着且强的正相关（p < 0.001）。此外，观看率DISCERN、GQS、有用性分数、喜欢、不喜欢和评论的数量显示出统计学上显着的正相关。结论 YouTube 视频中有关圆锥角膜治疗的内容质量普遍较好，对患者具有教育意义。增加医疗保健专业人员上传的视频数量将提高视频的质量、可靠性和信息量。
