More than 90 people in the United States have filed lawsuits against drug makers. They claim popular GLP-1 medicines caused vision loss.
These medicines are widely used to manage diabetes and support weight loss. The lawsuits focus on a rare eye condition called NAION.
NAION stands for non-arteritic anterior ischemic optic neuropathy. It is sometimes described as an “eye stroke.”
The condition affects the optic nerve and can cause sudden vision problems. In some cases, it may lead to permanent blindness.
The plaintiffs claim that using GLP-1 Drugs contributed to the development of NAION. However, medical experts say a direct connection has not been proven.
Research on the possible link has produced mixed findings. Some studies have reported a slight increase in the risk of the condition.
Other research has not found clear evidence connecting GLP-1 medicines with NAION. This means the safety issue remains under scientific investigation.
The European Medicines Agency has also examined the possible risk. It estimates that around one in every 10,000 diabetes patients using GLP-1 medicines may develop the vision disorder.
The condition remains considered rare among people taking these medicines. Researchers continue to study whether the medicines increase the risk.
GLP-1 medicines have become increasingly common in the United States. They are prescribed for diabetes treatment and, in some cases, weight management.
The lawsuits could bring further attention to the potential side effects of these Drugs. They may also lead to additional reviews of available safety data.
Patients using GLP-1 medicines should discuss any sudden vision changes with a healthcare professional. Early medical assessment can help identify serious eye problems.
The lawsuits represent claims made by patients and do not establish that the medicines caused their injuries. Further scientific and legal proceedings may provide more information about the alleged link.

For now, available evidence does not conclusively prove that GLP-1 medicines directly cause NAION.
