Eye stroke treatment put to the test: can clot busters save sight?

NCT ID NCT04965038

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether giving a clot-busting drug (tenecteplase or alteplase) within 4.5 hours of an eye stroke could restore vision. Eye stroke, or central retinal artery occlusion, is a blockage in the eye's main artery that often causes permanent vision loss. The trial aimed to enroll 127 people but was terminated early, so its findings are limited.
