Abstract

Purpose To investigate whether semaglutide increases the risk of nonarteritic anterior ischemic optic neuropathy (NAION) in the general population.Design This retrospective cohort study used a deidentified global electronic medical records database. The enrollment period was extended from January 2017 to August 2023, with observations concluding in August 2024.Participants This study included individuals with type 2 diabetes mellitus (T2DM) or obesity. They were further categorized into T2DM-only, obesity-only, and T2DM with obesity groups to assess the differences among these subgroups. The effects of semaglutide were compared with those of glucose-lowering or weight-loss medications other than glucagon-like peptide receptor agonists.Methods Patient data were obtained from 160 health care organizations across 21 countries. Outcomes were evaluated at 1, 2, and 3 years of follow-up. A 1:1 propensity score matching was performed to balance age, sex, body mass index, hemoglobin A1C, medications, and underlying comorbidities. Cox regression models were used to compute hazard ratios (HRs) and 95% confidence intervals (CIs).Main outcome measures The occurrence of NAION.Results The final analysis included 37 314 participants with T2DM only, 129 690 participants with obesity only, and 130 216 participants with both T2DM and obesity. The results indicated that the administration of semaglutide was not associated with the development of NAION in the T2DM-only group (1-year follow-up: HR, 2.32; 95% CI, 0.60-8.97; 2 years: HR, 2.31; 95% CI, 0.86-6.17; 3 years: HR, 1.51; 95% CI, 0.71-3.25), the obesity-only group (1-year follow-up: HR, 0.41; 95% CI, 0.08-2.09; 2 years: HR, 0.67; 95% CI, 0.20-2.24; 3 years: HR, 0.72; 95% CI, 0.24-2.16), and the T2DM with obesity group (1 year follow-up: HR, 0.81; 95% CI, 0.42-1.57; 2 years: HR, 1.2; 95% CI, 0.74-1.94; 3 years: HR, 1.19; 95% CI, 0.78-1.82).Conclusions The findings suggest that semaglutide may not be associated with an increased risk of NAION in the general population. Therefore, avoidance of semaglutide based solely on concerns regarding the risk of NAION may not be warranted because its potential benefits for blood glucose control and cardiovascular health likely outweigh its potential risks.Financial disclosure(s) The author(s) have no proprietary or commercial interest in any materials discussed in this article.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
