Red flags & when to go in person for Subconjunctival Hemorrhage

Audience: adult

A subconjunctival hemorrhage happens when a small blood vessel breaks just under the clear surface of your eye, causing a bright red patch. It often looks alarming but usually does not cause pain or affect vision. Most cases heal on their own within one to two weeks without treatment.

What is a Subconjunctival Hemorrhage?

A subconjunctival hemorrhage is bleeding underneath the clear membrane (conjunctiva) that covers the white part of your eye. It often looks like a bright red or dark patch on the white of the eye. This condition is usually painless and does not affect your vision. Common causes include minor eye injury, sudden increases in blood pressure from coughing or sneezing, or blood-thinning medications.

Common Symptoms and When It Usually Clears

You may notice a red spot on your eye that can spread but typically does not cause pain or discharge. Vision usually remains normal. The red area often fades over one to two weeks as the blood is absorbed. No treatment is usually needed, and the eye remains comfortable.
