Can weight loss drugs cause blindness? Check how

A recent research led by members of Massachusetts Eye and Ear hospital, US, found that patients with obesity who were prescribed weight loss drugs were diagnosed with a rare eye blinding condition.

The findings of this study are published in The Journal of the American Medical Association (JAMA) Ophthalmology.

According to the study, the patients have been diagnosed with 'Non-Arteritic Anterior Ischemic Optic Neuropathy' (NAION) that causes sudden vision loss in one eye. 

Patients with diabetes or obesity, who are commonly prescribed weight loss drugs such as Ozempic or Wegovy are more prone to blinding risks.

Such weight loss drugs contain protein semaglutide, which helps manage blood sugar by promoting insulin production.

NAION is a rare eye blinding condition that affects two to ten people per one lakh population, as per American Academy of Ophthalmology.

The researchers do not know why or how the rare eye condition can be linked with weight loss drugs. Further studies and research are required to detect the link.

The condition is thought to be caused by reduced blood flow to the optic nerve head, leading to permanent loss of vision in one eye.

The researchers included data from records of more than 17,000 patients at the hospital, who have been diagnosed with diabetes or obesity and were prescribed weight loss drugs.

According to Joseph Rizzo, director of the Neuro-Ophthalmology Service at the hospital, the patient should always discuss the risks of NAION before the physician prescribes weight loss drugs.
