A new meta-analysis has found that patients treated with glucagon-like peptide 1 receptor agonists (GLP-1 RAs) for obesity or diabetes appear to have a vrey low risk of developing nonarteritic anterior ischemic optic neuropathy (NAION), a rare condition that can lead to blindness.
This finding comes after a previous retrospective study suggested a potential link between semaglutide, a GLP-1 RA, and an increased risk of NAION.To further investigate this, researchers conducted a thorough analysis of 69 randomized controlled trials involving GLP-1 RAs for diabetes or obesity.
The meta-analysis, which included over 277,000 patient-years of data, found only five cases of NAION reported across all trials. “Of the 69 trials, only five reported cases of NAION — eight cases in the GLP-1 group and four in the control group; the remaining 64 trials did not report any case of NAION,” the study authors noted.
“GLP-1 treatment was not associated with an increased risk for NAION,” the researchers concluded.They emphasized that the absolute increase in risk with GLP-1 therapy was minimal, estimated at 2.6 per 100,000 patient-years.
“A relevant increase of the relative risk for a very rare, even though severe, condition does not modify the overall risk-benefit ratio of effective drugs, at least when appropriately prescribed,” the authors wrote.
However, they cautioned that the inappropriate use of GLP-1 RAs for weight loss in individuals with low cardiovascular risk could potentially lead to rare but serious side effects, including NAION.
the study, led by Dr.Giovanni Antonio Silverii of the University of Florence, was published in the journal Diabetes, Obesity and Metabolism.
While the findings are reassuring, the researchers acknowledge limitations. The rarity of NAION means that larger clinical trials are needed to definitively establish the safety of GLP-1 RAs, particularly semaglutide, which was involved in most of the reported NAION cases.
Additionally, the possibility of underreporting NAION could not be ruled out, and the trials did not specify whether the cases were arteritic or nonarteritic, which can pose a diagnostic challenge for ophthalmologists.
The study was conducted as part of the researchers’ institutional activities and did not receive specific funding.One author disclosed receiving consultancy and speaking fees from pharmaceutical companies unrelated to this study,as well as grants for the unit they direct.
