OBJECTIVE: To evaluate the quality and reliability of YouTube videos about Thyroid Orbitopathy.
METHODS: A YouTube search was performed using the keyword \'Graves eye disease\', \'thyroid eye disease\', \'thyroid orbitopathy\', \'thyroid ophtalmopathy\' in the search bar of YouTube. The first 50 videos were analyzed for each keywords, 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, country of origin, video type (patient experience, scholarly information), and described treatment technique 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, 94 videos met the criteria. The mean DISCERN, JAMA, GQS and usefulness score were 55.27 ± 16.57, 3.04 ± 0.64, 3.44 ± 0.93 and 3.23 ± 1.1. If we look at the upload source 53 (56.4%) videos were uploaded by physicians, 30 (31.9%) videos by institutions/private health institutions, 7 (7.4%) videos by health channels, 4 (4.3%) videos by patients. All scoring systems showed a statistically significant and strong positive correlation with each other (p < 0.001). A statistically significant positive correlation between viewing rate, likes and comments was observed. As the duration of the video increased, a significant increase in the scores in other scores was observed.
CONCLUSIONS: We observed that the tests we used in the scoring were correlated with each other. Most of the thyroid orbitopathy videos on YouTube were of good quality. Ophthalmologists should guide their patients who want to get information on YouTube to watch videos uploaded by health care professionals.

OBJECTIVE: It is aimed to determine the utility, reliability and quality of the lid loading videos on YouTube, a video sharing platform.
METHODS: A YouTube searches were made with the keywords \'Eyelid Loading,\' \'Gold Weight Implantation,\' \'Lid Loading for Lagophthalmos\' (without user login, cleared search history, in incognito tab). A total of 75 videos were recorded. Length of videos (seconds), number of views, uploaded source (doctor/health institution/medical channel), number of subscribers, number of likes, time since uploading (days), video content (surgical/theoretical information), type of narration (verbal narration/subtitle) were recorded. DISCERN, The Journal of the American Medical Association (JAMA), and Global Quality Scores of the videos were evaluated and recorded by two experienced oculoplastic surgeons (KSC, HT).
RESULTS: After the exclusion criteria, the remaining 46 videos were included in the study. The mean DISCERN score was 25.17 ± 6.88 (very poor quality), the JAMA score was 0.79 ± 0.63 (very poor quality), and GQS was 2.84 ± 1.03 (medium quality). Thirty videos (65.2%) had verbal narration, and 16 videos (34.8%) had subtitled narration. The DISCERN score and GQS were significantly higher in the videos with verbal narration compared to the narration with subtitles (p < 0.05). All three scores were positively correlated with each other. There was also a positive correlation between video length, number of subscribers, and DISCERN score.
CONCLUSIONS: The videos about lid loading on YouTube are of poor reliability, accuracy, and educational quality. The duration of the video and the type of narration can be kept in the foreground when choosing the video. Experts must review the content that is uploaded to websites like YouTube.

UNASSIGNED: The aim of the study was to assess the quality and reliability of videos on Fuchs endothelial corneal dystrophy (FECD) on YouTube.
UNASSIGNED: A search of YouTube was performed for the term \"FECD\" without any changes to the website\'s standard search preferences. The first 100 videos were recorded. A total of 71 videos were evaluated regarding the DISCERN score (min-max: 16-75), Journal of the American Medical Association (JAMA) score (min-max: 0-4), and Global Quality Scale (GQS) score (min-max: 0-5).
UNASSIGNED: The mean DISCERN score was 40.1±15.6 (moderate), the mean JAMA score was 2.01±0.7 (poor), the mean GQS score was 2.5±1.3 (moderate), and the mean video power index score was 106.8±135.7. Twenty-three of the videos (32.4%) were uploaded by physicians, 25 (35.2%) by universities/private hospitals, and 21 (29.6%) by health channels. Thirty-six videos (50.7%) contained information about the disease, 24 (33.8%) discussed surgical techniques, and 11 (15.5%) were about patient experience.
UNASSIGNED: YouTube provides only moderate-quality health information on FECD. Physicians and professional organizations should be aware of and embrace this evolving technology to raise awareness about FECD.

OBJECTIVE: 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.
CONCLUSIONS: 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.

UNASSIGNED: This study investigated the quality of YouTube videos addressing multifocal intraocular lens (IOL) as educational resources.
UNASSIGNED: An online search of YouTube was performed for the terms \"multifocal lens implants\" and \"multifocal iol\". A total of 339 videos were recorded. After these videos were investigated, the final remaining 140 videos were enrolled in the study. All videos were evaluated in terms of their DISCERN, Journal of the American Medical Association (JAMA), and Global Quality (GQ) scores by two independent experienced ophthalmologists.
UNASSIGNED: The median DISCERN score was 33 (poor quality), JAMA score was 1.25 (lowest quality), and GQ score was 2 (poor quality). Of the 140 videos, 80 videos (57.1%) were uploaded by physicians and another 60 videos (42.9%) were uploaded by non-physicians. There was no statistically significant difference in general characteristics of the videos between the physicians and non-physicians groups. Also, their mean DISCERN, JAMA and GQ scores were similar between the groups (p = .101, p = .441 and p = .209, respectively).
UNASSIGNED: Our findings suggest that the content of YouTube videos regarding multifocal IOLs is of generally poor quality and is not adequately educational for patients. Nevertheless, to ensure patients\' access to accurate medical information, we believe that the content and reliability of medical information obtained from online videos should be examined by healthcare specialists from the viewpoint of patients.

Purpose: The objective of this study was to analyze the quality of videos on YouTube as educational resources about keratoplasty surgery.Methods: The first 100 videos found after the keyword \"keratoplasty for patients\" was used in the YouTube search engine were included in the study. General video assessment included duration, views, likes, dislikes, and comments. The quality and accuracy of the information were evaluated by 2 independent ophthalmologists using DISCERN score, Journal of the American Medical Association (JAMA) score, global quality score and usefulness scoring system. Interobserver agreement and individual correlations of the data of each video were statistically analyzed.Results: Eighty-four of the first 100 videos met the inclusion criteria. The mean DISCERN score was 42.11, the mean JAMA score was 1.82, the mean global quality score was 2.35, and the mean usefulness score was 2.01. Twenty-eight (33.3%) of the surgical procedures described in the videos were penetrating keratoplasty, 18 (21.4%) were DMEK, 13 (15.5%) were DALK, four (4.8%) were DSAEK, and one (1.2%) was keratoprosthesis, while the remaining 20 (23.8%) videos did not mention any surgical procedure. Of the 84 videos, 26 (31%) had been uploaded by physicians, 46 (54.8%) by university/private health institutions, 11 (13.1%) by health channels, and one (1.2%) by a patient.Conclusion: YouTube is an important platform that can be used by patients to acquire information about keratoplasty. Increasing the number of uploads of informative keratoplasty videos by healthcare professionals will provide higher quality, more reliable, and more instructive content in this area.
