The quality, reliability and educational values of YouTube videos for low vision patients.

Clinical relevance: Access to high-quality educational resources is essential for patients with low vision. Providing curated recommendations for reliable materials can help ensure patients receive accurate information for effective visual health management.

Background: Visual impairment is a global issue affecting millions. The internet serves as a significant source of information, but the quality and reliability of this information can vary greatly.

Methods: An online search on YouTube was conducted using keywords such as 'Low Vision', 'Vision Impairment', 'Low Vision Aids', and 'Low Vision Rehabilitation'. Videos were screened based on inclusion criteria, and those that did not meet these criteria were excluded. The selected videos were assessed using three evaluation tools: modified DISCERN criteria (mDISCERN), JAMA benchmark criteria, and Global Quality Score (GQS). Three low-vision optometrists independently performed the assessments, and video popularity was measured using the video power index (VPI).

Results: A total of 116 videos were included in the analysis. The Kruskal-Wallis test indicated significant differences between the results of the three video evaluation tools and video quality (p < .001). The comparison between videos produced by universities vs. professional organisations vs. private companies showed no significant differences between groups and VPI (p = .522), but a significant difference was found with mDISCERN (p < .001), JAMA (p < .001), and GQS (p = .014). No significant differences in quality were found in gender analysis.

Conclusions: YouTube can be a valuable source of information for low vision patients, but healthcare providers need to guide patients towards high-quality resources while ensuring oversight of the content.
