GLP-1 drugs such as Ozempic have transformed healthcare in recent years, dramatically altering how we treat conditions like type 2 diabetes and obesity. In the study, GLP–1 usage was associated with an estimated 18 percent lower rate of developing AMD over time. Previous research had uncovered evidence of a similar protective effect from GLP-1 drugs against AMD, with many studies involving people with type 2 diabetes – the disease GLP-1 drugs were first used to treat. As for why exactly GLP-1 drugs might protect older adults from vision loss, we can't yet be sure. "Weight loss per se reduces systemic inflammation and oxidative stress, which may independently reduce AMD risk," the researchers explain in their study.
