Ozempic, Wegovy Linked to Rare Vision Loss: EMA Investigates
Table of Contents
The European Medicines Agency (EMA) is investigating a potential link between semaglutide medications, including Ozempic and Wegovy, and an increased risk of vision loss. This comes after reports of a rare eye condition known as non-arteritic anterior ischemic optic neuropathy (NAION) in patients using these drugs, which are prescribed for type 2 diabetes and weight management.
Semaglutide medications have gained popularity for their effectiveness in controlling blood sugar and promoting weight loss. However, emerging data suggests a need for increased awareness regarding potential ocular side effects. The EMA’s investigation aims to determine the strength of the association and update product data accordingly.
EMA Confirms Rare Eye Condition Link
The EMA confirmed that NAION is a “very rare side effect” associated with semaglutide treatments. This condition can lead to vision loss,often in one eye. The agency estimates that NAION may affect up to 1 in 10,000 people taking semaglutide. In individuals with type 2 diabetes, the risk is approximately twice as high compared to those not taking the medication, according to the EMA website.
The agency recommends updating the product information for semaglutide drugs to include this potential side effect. Novo Nordisk, the manufacturer of Ozempic and Wegovy, stated that it is working with the EMA to update labels, according to Reuters. The company maintains that the “benefit-risk profile of semaglutide remains favorable.”
Did You Know? NAION occurs when blood flow to the optic nerve is blocked, causing damage and potential vision loss. risk factors include diabetes, high blood pressure, and high cholesterol, according to the National Eye Institute.
Increased Risk of Macular Degeneration
In addition to NAION, a large-scale study published in JAMA Ophthalmology in early June 2025 found that patients taking semaglutide had at least twice the risk of developing neovascular macular degeneration (DMLA), also known as wet age-related macular degeneration (AMD). Wet AMD is a leading cause of vision loss in older adults, characterized by abnormal blood vessel growth in the macula, the central part of the retina.
The study,which analyzed data from thousands of patients,highlights the importance of regular eye exams for individuals taking semaglutide medications. Early detection and treatment of wet AMD can help slow the progression of the disease and preserve vision.
Pro Tip: If you are taking Ozempic or Wegovy, schedule regular eye exams with an ophthalmologist to monitor for any changes in your vision.
Symptoms and Recommendations
The EMA advises patients taking semaglutide to contact their doctor immediately if they experience sudden vision loss or a rapid decrease in vision. prompt medical attention is crucial for diagnosing and managing potential eye-related complications.
Symptoms of NAION may include blurred vision, vision loss in one eye, or a visual field defect. Symptoms of wet AMD can include distorted vision, blurred central vision, and difficulty seeing in low light.
Semaglutide Medications: Benefits and Risks
Semaglutide medications offer significant benefits for individuals with type 2 diabetes and obesity. They can definately help lower blood sugar levels, promote weight loss, and reduce the risk of cardiovascular events. However, like all medications, they also carry potential risks. It is essential to weigh the benefits and risks carefully with your doctor before starting semaglutide treatment.
The ongoing investigation by the EMA underscores the importance of continuous monitoring and evaluation of drug safety. As new data emerges, healthcare professionals and patients can make informed decisions about treatment options.

Evergreen Insights: Background,Context,Ancient Trends
Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist,a class of drugs that mimics the effects of the natural hormone GLP-1. GLP-1 helps regulate blood sugar levels and promotes satiety, leading to weight loss. Ozempic is approved for the treatment of type 2 diabetes, while Wegovy is approved for chronic weight management in adults with obesity or overweight and at least one weight-related condition.
The use of GLP-1 receptor agonists has increased significantly in recent years, driven by the rising prevalence of diabetes and obesity. While these medications have proven effective, ongoing research is essential to identify and manage potential long-term risks.
FAQ: Ozempic and Wegovy Vision Loss Concerns
