The U.S. FDA has ordered GLP-1 drugmakers to add warnings about a rare eye condition called non-arteritic anterior ischemic optic neuropathy (NAION), which can cause sudden, permanent blindness. This condition, often described as an "eye stroke," results from reduced blood flow to the optic nerve and leads to painless vision loss in one eye. There is currently no proven treatment for NAION.
