Compliance with Web Content Accessibility Guidelines in Ophthalmology Social Media Posts

This is a cross-sectional analysis of publicly available Internet data to examine compliance to Web Content Accessibility Guidelines (WCAG) on patient education social media posts in ophthalmology. WCAG ensures web content accessibility for those with disabilities (including visual impairment). Social media posts were sampled from 10 ophthalmology patient education social media pages and 10 non-ophthalmology (cardiopulmonary) pages as the comparison group. Three independent reviewers graded the selected posts based on the WebAIM© WCAG 2 checklist adapted for social media posts. Validated accessibility standard labels: "0" for not meeting any standards, "1" for meeting bare minimum accessibility requirements, "2" for meeting legal accessibility requirements, or "3" for exceeding accessibility requirements. There were no significant differences between ophthalmology and non-ophthalmology posts in receiving high vs. low WCAG grades. 49% of ratings for ophthalmology social media posts showed no compliance with any WCAG. The most common reasons that ophthalmology posts failed to meet criteria were due to color and contrast issues (38.9%). Most ophthalmology social media posts had low WCAG scores, indicating poor compliance to WCAG. Because social media is highly visual, reduced compliance to WCAG may create barriers for low vision individuals to successfully access patient education social media content.
