Study links popular weight loss drugs to rare blinding eye condition

Researchers at Massachusetts Eye and Ear Hospital, US, found that patients with obesity who were prescribed these weight loss drugs were over seven times more likely to be diagnosed with NAION, or 'Non-Arteritic Anterior Ischemic Optic Neuropathy', causing sudden vision loss in one eye. They also found that patients with diabetes who were taking these semaglutide-containing drugs were over four times likely to get a NAION diagnosis.
