Hyphema (hi-FEE-ma) is a condition that happens when blood collects in the front part of the eye.
An eye injury and certain medical conditions can cause blood to collect in the anterior chamber (the space in the eye behind the cornea and in front of the iris and lens). This is called a hyphema.
Blood may cover part or all of the iris and the pupil, partly or totally blocking vision in that eye. Hyphema may cause eye pain, sensitivity to light, blurred vision, vision loss, eye discomfort, nausea, or vomiting. Sometimes the blood can increase pressure in the eye.
The goal of treating hyphema is to clear the blood, treat any increase in eye pressure, and prevent re-bleeding.
Hyphema is a serious condition that usually improves over a few days to weeks. Most people respond well to treatment. Your eye doctor will recommend follow-up testing or treatment.
