Subconjunctival Haemorrhage

Bleeding between the white of the eye and the conjunctiva, the membrane covering the white of the eye and lining the eyelids

  • Age, gender, genetics, and lifestyle as risk factors depend on the cause

Ruptured blood vessels in the conjunctiva, the clear membrane covering the white of the eye and lining the eyelids, cause bleeding under the membrane. The condition, called subconjunctival haemorrhage, is common because the blood vessels in the conjunctiva are easily damaged. The bleeding causes a red area over the white of the eye.

The condition may result from a minor eye injury, sneezing, coughing, or, rarely, a bleeding disorder. Most often, it is spontaneous, especially in elderly people. Although the haemorrhage looks dramatic, it is generally painless and usually clears up without treatment within 2–3 weeks. If the eye is painful or the redness persists, you should consult your doctor.
