Semaglutide, the active ingredient, treats diabetes and aids weight loss, but may cause NAION

Diabetes patients on semaglutide are four times likelier to develop non-arteritic anterior ischemic optic neuropathy (NAION)

Overweight or obese individuals using these drugs are seven times likelier to develop NAION

NAION occurs when blood flow to the optic nerve is reduced or blocked

Sudden, painless vision loss in one eye is a typical symptom, often noticed upon waking

There are no current treatments for NAION, and vision often remains impaired

The study, published in JAMA Ophthalmology, was led by Harvard professor Joseph Rizzo

Despite the increased risk, NAION remains relatively uncommon, affecting 10 out of 100,000 people

Researchers examined over 16,000 patients' data, finding higher NAION rates in semaglutide users compared to others
