More than 90 people in the United States have filed lawsuits against manufacturers of popular GLP-1 medicines.
The plaintiffs allege that the drugs caused serious vision problems, including cases of permanent vision loss.
Lawsuits Focus on Rare Eye Condition
According to reports, the plaintiffs say they developed non-arteritic anterior ischemic optic neuropathy (NAION) after using GLP-1 medicines.
NAION is sometimes described as an “eye stroke.” It can cause sudden vision loss and, in some cases, permanent damage.
However, medical experts say there is currently no conclusive evidence proving that GLP-1 medicines directly cause NAION.
Some studies have reported a small increase in risk among users. Other research has found no clear connection between the medicines and the condition.
What Experts Say About Vision Risks
The European Medicines Agency estimates that around one in 10,000 people with diabetes taking GLP-1 medicines may develop the eye condition.
GLP-1 medicines such as Ozempic and Wegovy are widely used to control blood sugar and support weight loss.
Doctors also say rapid changes in blood sugar can temporarily affect the eye’s lens. This can cause blurred vision.
Such changes generally improve within three to four months, according to medical guidance cited in reports.
Doctors Advise Regular Eye Checks
Experts recommend regular eye examinations for people taking GLP-1 medicines, particularly those with diabetes.
Anyone experiencing sudden or unusual changes in vision should seek prompt medical attention from an eye specialist.
The lawsuits are ongoing, while the scientific debate over any potential connection between GLP-1 medicines and NAION continues.
