Dr. Allen also discusses diabetic retinopathy, macular degeneration and the importance of receiving a comprehensive dilated eye exam before or shortly after beginning a GLP-1 medication.GLP-1 medications can provide important benefits for diabetes, weight management and cardiovascular health. This episode is not intended to tell anyone to stop taking them.

Some people lose the upper or lower half of their visual field or notice that colors appear less vivid.🔹 The absolute risk of NAION appears to be low, but research continues to examine a possible association with semaglutide and other GLP-1 medications.🔹 People over 50 and those with diabetes, high blood pressure, high cholesterol, obstructive sleep apnea or a crowded optic nerve may have additional risk factors.🔹 Do not stop taking a prescribed GLP-1 medication without speaking with your prescribing doctor. Ask whether you should receive a baseline comprehensive dilated eye exam and how frequently your eyes should be monitored.Resources & Research MentionedAmerican Optometric Association GLP-1 Clinical Report:https://www.aoa.org/AOA/Documents/Practice%20Management/Clinical%20Guidelines/AOA%20GLP-1_EBO_clinical-report.pdfSemaglutide and the Risk of NAION:https://jamanetwork.com/journals/jamaophthalmology/fullarticle/2820255GLP-1 Receptor Agonists and Neovascular Age-Related Macular Degeneration:https://jamanetwork.com/journals/jamaophthalmology/article-abstract/2834964GLP-1 Receptor Agonists and Eye Health Research:https://pubmed.ncbi.nlm.nih.gov/40631457/GLP-1 Vision-Loss Lawsuits: https://www.reuters.com/legal/government/lawsuits-claiming-ozempic-other-glp-1s-led-blindness-become-second-mass-2025-12-15/Semaglutide and Cardiovascular Outcomes, SUSTAIN-6 Trial:https://www.nejm.org/doi/10.1056/NEJMoa1607141Find an Eye Doctorhttp://bit.ly/4bj9ujzLow-Vision ResourcesAPH ConnectCenter Blindness and Low-Vision Support:https://aphconnectcenter.org/blindness-low-vision-support-resources/State Vocational Rehabilitation Agencies:https://rsa.ed.gov/about/statesEye Health ProductsMy Top 5 Dry Eye Drops:https://www.amazon.com/shop/doctoreyehealth/list/15I8QLDA5IEVX?ref_=aipsflistAllergy Relief Products:https://www.amazon.com/shop/doctoreyehealth/list/3U4XQXC21I5H9?ref_=aipsflistMacular Support for AMD:https://www.amazon.com/shop/doctoreyehealth/list/36B78D5BV2WWT?ref_=aipsflistDry Eye Supplements:https://www.amazon.com/shop/doctoreyehealth/list/11OBTPPBDEWD5?ref_=aipsflistEyelid and Eyelash Care:https://www.amazon.com/shop/doctoreyehealth/photo/amzn1.shoppablemedia.v1.collage.da009d66-35a9-467b-b355-9e32a7477d66?ref_=aipsfphotoErgonomics Support for Eyestrain:https://www.amazon.com/shop/doctoreyehealth/list/1Z77TPOQ9LHKB?ref_=aipsflistDry Eye PM Support:https://www.amazon.com/shop/doctoreyehealth/list/DDYUZXFKCMA6?ref_=aipsflist⚠️ DISCLAIMER: This episode is for educational purposes only and does not replace professional medical advice, diagnosis or treatment.
