Beware of Sensationalizing the Potential Semaglutide-NAION Link

Few articles analyzed in this study situated NAION within its known risk factors, including its associations with age, diabetes, hypertension and obstructive sleep apnea. Without this information, the semaglutide-NAION link may seem more novel or direct than warranted. Misinformation can arise not just from factual inaccuracies but also from exclusion of context or distortion of framing. Photo: Michael Trottini, OD, and Candice Tolud, OD. Click image to enlarge. In July 2024, a single-center, retrospective matched cohort study published in JAMA Ophthalmology reported a higher cumulative incidence of nonarteritic anterior ischemic optic neuropathy (NAION) among patients prescribed semaglutide than those on non-GLP-1 medications. However, the authors emphasized that causality could not be inferred from observational data and called for further research.Despite this disclaimer, the study received widespread media attention. Given the rarity of NAION and the potential for news coverage to shape public perception, researchers based in Canada conducted a systematic content analysis of English-language news articles to evaluate how those original study findings were reported, with a particular focus on scientific accuracy, certainty framing and source attribution. The team determined that media coverage of the potential semaglutide-NAION link varied in accuracy and tone.“Articles avoiding causation errors more often included expert input and contextualized uncertainty,” they emphasized in their paper. “These findings highlight the need for responsible health journalism in reporting emerging safety concerns.”This qualitative content analysis, recently published in Journal of Neuro-Ophthalmology, included 71 articles over an eight-month period (July 3, 2024, to March 31, 2025). Articles were coded by three independent reviewers using a structured tool to assess scientific accuracy, causal language, framing of certainty, citation of the original study, quoted sources and emotive or misleading language.Across the 71 articles analyzed, 21% used language suggestive of a direct causal link, and 87% framed the relationship as “likely” or “certain.” These patterns concerned the study authors, given the absence of strong mechanistic or epidemiologic evidence supporting causality. Their findings reflected broader issues in science communication, where simplified and emotionally resonant narratives often overshadow nuanced scientific reporting. Our article on the original study discussed here was the most-read news story of 2024 by Review of Optometry readers. Articles with causation errors were less likely to correctly define NAION (73% vs. 92%), quote physicians (33% vs. 63%) or mention study limitations (27% vs. 66%). US articles had the lowest rate of causation errors (5%) and UK articles had the highest (34%).“Articles implying causation frequently relied on framing tactics such as vivid personal narratives and dramatic descriptions of sudden vision loss. These stories were often presented without clinical counterpoints, acknowledgment of uncertainty or reference to regulatory or epidemiologic evidence,” the researchers noted. “Instead, the language tended to exaggerate certainty and urgency, deviating from the cautious tone of the original study.”Despite the prevalence of causation errors in our sample, several articles demonstrated strong reporting practices. These included clear statements about uncertainty, citation of original studies and regulatory sources, and avoidance of exaggerated headlines. The study authors believe that these examples highlight that accurate and responsible reporting is possible even in the face of emerging and incomplete scientific evidence. Although this study focused on traditional news media, the team suggested that further research should examine how narratives about GLP-1 drugs and NAION circulate on social media platforms such as Facebook, TikTok and YouTube.“These spaces, which often operate with minimal editorial oversight, can rapidly amplify emotionally charged or misleading content and reach audiences less exposed to professional journalism,” they wrote in their paper. “Examining how such platforms influence public understanding, patient behavior and medication adherence would provide valuable insight into the broader consequences of health communication.”Click here for the journal source.
