Research suggests a potential link between certain weight loss drugs, including Ozempic and Wegovy, and an increased risk of vision loss and "eye stroke". Some studies indicate that Wegovy may carry a higher risk of these conditions compared to Ozempic, with one finding that Wegovy users have a significantly greater risk of sudden sight loss. The extent of this risk and the comparison between different GLP-1 drugs is being reported by various outlets, with some highlighting the potential for a rare blinding condition.
