GLP-1 NAION Lawsuit MDL 3163 Case Management Orders (CMOs)
Below is the chronological log of Case Management Orders (CMOs) and foundational legal filings entered in MDL 3163: In Re: GLP-1 Receptor Agonists NAION Products Liability Litigation.
This litigation handles lawsuits alleging that certain GLP-1 receptor agonists (such as Ozempic) can cause Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION). NAION is a severe eye complication that can lead to permanent vision loss.
Like its sister litigation (MDL 3094, which handles gastrointestinal injuries caused by GLP-1s), MDL 3163 is centralized in the U.S. District Court for the Eastern District of Pennsylvania under the supervision of the Honorable Karen Spencer Marston.

Key Context & Litigation Overview
What is NAION?
Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION) occurs when blood flow to the optic nerve head is compromised, causing sudden, irreversible vision loss, typically impacting only one eye at a time. Recent clinical data and case reports have discovered a potential vascular or metabolic link between rapid glycemic changes caused by semaglutide/GLP-1 receptor agonists and the onset of ischemic optic events.
Why is there a Separate GLP-1 Docket for NAION (MDL 3163)?
While the initial GLP-1 MDL (MDL 3094) focuses extensively on systemic gastrointestinal injuries, such as gastroparesis, bowel obstructions, and ileus, the distinct medical, scientific, and causation arguments surrounding blindness and optic nerve damage required a targeted management framework. Judge Marston utilizes a streamlined structure to handle these unique injury claims efficiently and separately from the GI injuries. Having both GLP-1 MDLs under the same judge creates numerous efficiencies, because the judge already has a baseline understanding of GLP-1s and the defendants.
