Parker Waichman LLP Files Lawsuit over Eye Condition Linked to Mounjaro

PORT WASHINGTON, N.Y., Nov. 2, 2026 /CourierPR/ -- Parker Waichman LLP, a national law firm, has filed a lawsuit on behalf of a Texas resident who developed an irreversible eye condition, non-arteritic anterior ischemic optic neuropathy (NAION), after taking Mounjaro, a GLP-1 medication produced by Eli Lilly. This latest filing, made on October 29, 2026, brings the total number of lawsuits filed by the firm to multiple cases involving similar claims.

NAION is a condition that can cause partial or complete permanent vision loss in one or both eyes by cutting off blood flow to the optic nerve. Parker Waichman has been advocating for patients who have suffered from this condition after taking GLP-1 receptor agonist medications, including Mounjaro. The firm has urged individuals who have experienced serious eye injuries after using these medications to contact them for a free case review.

Regulators outside the United States have already taken steps to address the risks associated with these medications. On June 23, 2026, Health Canada updated the Product Monograph for Mounjaro to include NAION safety information. On July 23, 2026, Australia's Therapeutic Goods Administration (TGA) announced NAION-related updates to the Product Information for GLP-1 receptor agonists, including Mounjaro. These updates advise that NAION has been reported in patients treated with these medications and that sudden vision loss should prompt urgent ophthalmologic evaluation.

The lawsuit filed by Parker Waichman alleges that Eli Lilly failed to adequately warn patients and physicians in the United States about the risk of NAION and permanent vision loss associated with Mounjaro. The firm is currently accepting cases nationwide for individuals who have suffered vision loss, blindness, or serious optic nerve damage after taking Mounjaro, Zepbound, Ozempic, Wegovy, or other GLP-1 medications. Victims may be entitled to compensation for medical expenses, lost wages, pain and suffering, and other damages.
