Cross-sectional study evaluates amblyopia video quality on TikTok and Bilibili, highlighting the need for specialist content.

This study aims to assess the quality and reliability of amblyopia-related videos on popular short video platforms.
Collected data from 150 amblyopia-related videos on TikTok and Bilibili.
Measured video quality using Global Quality Score (GQS) and modified DISCERN (mDISCERN) tools.
Analyzed user engagement metrics like likes, comments, and shares.
Utilized Mann-Whitney U and Kruskal-Wallis tests for comparisons and Spearman correlation for analysis.
A total of 199 videos were analyzed, with TikTok videos being significantly shorter than Bilibili's.
TikTok exhibited higher user engagement metrics across the board.
The median GQS and mDISCERN scores for videos were both 3.00, indicating suboptimal quality.
Videos by specialists received higher scores than those by non-specialists.
A weak positive correlation was found between video duration and quality.

Zhu et al. (2026) studied this question.
