Abstract

Importance: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are associated with increased risk of diabetic retinopathy (DR) and nonarteritic anterior ischemic optic neuropathy (NAION). The risk of sight-threatening complications associated with GLP-1 RAs is underexamined. Objective: To investigate whether the use of GLP-1 RAs in patients with T2D is associated with the development of DR, NAION, or DR complications. Design, Setting, and Participants: This retrospective cohort study of adults (aged ≥18 years) with T2D and a recent hemoglobin A 1c level of 6.5% or higher was conducted between January 1, 2015, and September 30, 2022, using the TriNetX database. The cohort was divided into 2 groups, adjusted for baseline characteristics through propensity score matching (PSM), based on whether the individuals received prescriptions for a GLP-1 RA. The statistical analysis was conducted on October 10, 2024. Exposures: At least 2 prescriptions of a GLP-1 RA given 6 months apart. Main Outcomes and Measures: Cox proportional hazard regression models were used to evaluate the primary outcome: association between GLP-1 RAs and the risk of incident DR, NAION, or sight-threatening complications over a 2-year follow-up period. Results: After PSM, 185 066 individuals (mean [SD] age, 59.0 [12.5] years; 93 389 females [50.5%]) were prescribed GLP-1 receptor agonists. Use of GLP-1 RAs was associated with an increased incidence of DR (hazard ratio [HR], 1.07; 95% CI, 1.03-1.11), while no statistically significant difference was observed in the risk of NAION (HR, 1.26; 95% CI, 0.94-1.70). In a subgroup analysis of 32 695 patients with preexisting DR, GLP-1 RAs were not associated with progression to proliferative DR (HR, 1.06; 95% CI, 0.97-1.15) or diabetic macular edema (HR, 0.98; 95% CI, 0.95-1.01) but were associated with a lower occurrence of vitreous hemorrhages (HR, 0.74; 95% CI, 0.68-0.80), neovascular glaucoma (HR, 0.78; 95% CI, 0.68-0.88), or blindness (HR, 0.77; 95% CI, 0.73-0.82). Conclusions and Relevance: In this cohort study of individuals with T2D, GLP-1 RA use was associated with a modestly increased risk of incident DR; however, fewer patients experienced sight-threatening DR complications, including blindness, even among those with preexisting DR. These findings suggest that all patients with T2D treated with GLP-1 RAs, regardless of preexisting DR, should be regularly screened and monitored for potential complications of T2D.

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.
