Key Takeaways
- Ophthalmic complications were observed in patients using semaglutide and tirzepatide, but a causal link was not established.
- The study included nine patients, with conditions like nonarteritic ischemic anterior optic neuropathy and bilateral papillitis identified.
The main outcomes were the measurements of the visual acuity and visual field defects.

Bradley J. Katz, MD, PhD, and colleagues reported that ophthalmic complications were observed in patients taking drugs prescribed to treat diabetes, specifically, semaglutide and tirzepatide, although a causal relationship could not be established.1
Katz is the first author of the study and is from the John A. Moran Eye Center, Department of Ophthalmology & Visual Sciences, Department of Neurology, University of Utah Health, Salt Lake City.
The rationale for the study, according to the authors, is that “Nearly 2% of the US population received a prescription for semaglutide in 2023. There has been a recent concern that this drug and other similar medications may be associated with ophthalmic complications.”
In light of this, Katz and colleagues conducted a retrospective case series that included patients who had been evaluated initially in a community setting. The analysis included patients with an ophthalmic complication in association with the use of semaglutide or tirzepatide, they explained
The main outcomes were the measurements of the visual acuity and visual field defects.
Study identifies ocular findings
The analysis included 9 patients (5 women; mean age, 57.4 years; age range, 37-77 years). Of the 9 patients, 7 patients had nonarteritic ischemic anterior optic neuropathy and 1 patient each had bilateral papillitis and paracentral acute middle maculopathy. The reported atypical features included sequential ischemic optic neuropathy, bilateral disc swelling at presentation, and progressive vision loss.
The investigators commented, “In this case series study, it was not possible to determine if there is a causal link between these drugs and the ophthalmic complications reported. In some cases, it is hypothesized that rapid correction of hyperglycemia induced by these drugs, rather than a toxic effect of the drugs, could be associated with the ophthalmic complications reported.”
