GLP-1 Medications and Your Eyes: What You Should Know
Medications like Ozempic®, Wegovy®, Mounjaro®, and other GLP-1 receptor agonists are becoming more common for people managing diabetes and for weight loss. These medicines can be very helpful, but many patients have questions about how they might affect the eyes.
As an ophthalmologist, I’d like to share what we currently know about the benefits and possible risks to vision.

Possible Benefits for the Eyes
Research is still early, but some studies suggest GLP-1 medicines might actually protect eye health in certain ways:
• Lower risk of macular degeneration – Patients taking GLP-1 medications have been found to have a lower chance of developing some forms of age-related macular degeneration (AMD), a leading cause of vision loss.
• Lower risk of glaucoma – Some data suggest a reduced risk of glaucoma, which damages the optic nerve and can lead to vision loss if untreated.
• Better overall blood sugar control – By improving diabetes management, these medications may help reduce long-term damage to the tiny blood vessels in the eyes.

Possible Risks to the Eyes
While benefits are promising, there have also been reports of potential risks:
• Temporary worsening of diabetic eye disease – If blood sugar improves very quickly, some people with diabetes may see a short-term worsening of diabetic retinopathy (bleeding or swelling in the retina).
• Vision changes – Blurry vision, sudden vision loss, or visual field changes have been reported, though these are rare.
• Optic nerve concerns – Some studies have suggested a link between GLP-1 medications (especially semaglutide) and a condition called non-arteritic anterior ischemic optic neuropathy (NAION), which can cause sudden vision loss. This is still being studied and is not proven.
• Age-related macular degeneration (wet type) – A few studies have shown a possible increased risk of the “wet” form of AMD, but other studies suggest the opposite. More research is needed.

What Patients Should Do
If you are taking, or planning to start, a GLP-1 medication:
• Get a baseline eye exam before or soon after starting. This helps detect any hidden problems early.
• Follow up regularly, especially if you have diabetes, glaucoma, or macular degeneration. Your eye doctor will guide how often you should be checked.
• Report any sudden vision changes right away – including blurriness, loss of vision, flashing lights, or new blind spots.
• Work with your medical team – your eye doctor, primary doctor, and endocrinologist should all be aware you’re using GLP-1 therapy.

The Bottom Line
GLP-1 medications are powerful tools for diabetes and weight loss, and they may also provide benefits for eye health. At the same time, there are some possible risks, particularly for patients with existing eye disease.
The best step is close monitoring. By partnering with your ophthalmologist, you can safely take advantage of the benefits of these medicines while protecting your vision.
