New data raises questions about ocular side effects from popular medications like Ozempic, Wegovy, and Mounjaro—especially when used long-term.

???? What the Research Found
A population-based study from Ontario, Canada (2020–2023) tracked over 139,000 adults with type 2 diabetes:
• 46,334 had used GLP 1 receptor agonists (mostly semaglutide) for ≥6 months
• 92,668 had never used them
Key findings:
• GLP 1 users were more than twice as likely to develop wet AMD overall
• Risk increased to over 3× for those on the medication for 30+ months
• Despite the relative increase, absolute rates were low—0.2% vs. 0.1%

???? What It Means for You
Consideration Explanation
???? Association ≠ Causation Experts caution that factors like smoking or UV exposure weren’t fully accounted for health.com
???? Still rare Only 2 additional cases per 1,000 people using GLP 1s
???? Dose-dependent effect Risk grows with longer duration of use

???? What Patients Should Carefully Monitor
• Maintain annual eye exams—especially if you’re 60+ with diabetes
• Be alert for new visual symptoms: distorted lines, blind spots, glare
• Talk to your endocrinologist and ophthalmologist if you’re taking GLP 1s long-term

???? Expert Guidance
• The American Association of Clinical Endocrinology doesn’t recommend stopping GLP 1s but advises informed discussions https://www.health.com/ozempic-wet-amd-study-11750409?utm
• The American Academy of Ophthalmology encourages closer retinal monitoring when using GLP 1s https://www.beckershospitalreview.com/glp-1s/semaglutide-tied-to-increased-risk-of-eye-disease-4-study-takeaways/?utm

✅ Bottom Line
• New research shows a 2×–3× relative increase in wet AMD risk among long-term GLP 1 users
• But the overall incidence remains low
• The benefits of GLP 1s—for weight, glucose control, and heart health—likely still outweigh this small risk
• Still, regular eye exams and open communication between doctors are essential
???? If you’re taking Ozempic, Wegovy, Mounjaro, or other GLP 1 medications, talk to your healthcare providers about personalized screening—a proactive approach can help preserve both your health and your vision.
