Eye popping study reveals hidden triggers for Blood-Red eyes
NCT ID NCT07247071
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at what might cause a non-traumatic subconjunctival hemorrhage, a red patch on the eye that looks scary but is harmless and goes away on its own. Researchers studied 67 adults to find risk factors like coughing, sneezing, or blood thinners. The goal was to help doctors spot underlying health problems early.
