Rutgers researchers found GLP-1 drugs such as Ozempic and Wegovy were linked to a small increase in a rare eye condition that can cause sudden vision loss. The risk remained very low, but the study says it warrants monitoring.
01Summary
- 01The study, published in Annals of Internal Medicine, examined US adults aged 18 to 65 with type 2 diabetes who had recently started treatment.
- 02Researchers found a modest increase in ischemic optic neuropathy among people taking GLP-1 receptor agonists, including semaglutide and tirzepatide.
- 03The reported increase was about three to four extra cases per 10,000 patients treated with GLP-1s over 18 months.
- 04Cases were more common among men and among adults aged 50 to 65 in the study population.
- 05The researchers said the study does not prove the medicines directly cause optic nerve damage.
02Why it matters
The drugs are used by millions of people for diabetes and weight loss, so even a rare side effect is important to track. The findings highlight the need to act quickly if someone taking these medicines has sudden vision changes.
