Scientists Develop Experimental Eye Drop That Could Transform Dry Eye Treatment

Researchers at Baylor College of Medicine and Okayama University tested a rexinoid eye drop, NEt-3IB, in mice with dry eye disease.

The treatment shifted resident macrophages into a protective state, lowered inflammation, and reduced corneal surface damage.

It also helped preserve goblet cells, which support the eye’s natural defenses and tear film.

The findings suggest a potential steroid-free alternative for dry eye, though human studies are still needed.
