The conjunctiva—the transparent membrane covering the white of the eye—contains many tiny blood vessels. When one ruptures, blood collects under this layer, causing a bright red patch known as a subconjunctival haemorrhage. Although it may look dramatic, it usually doesn’t cause pain, vision changes, or discharge. Mild itching may be experienced.
Common triggers include sneezing, coughing, eye rubbing, vomiting, or minor trauma. It may also be linked with conditions like high blood pressure, blood clotting disorders, or use of blood-thinning medications.
Diagnosis
In most cases, diagnosis is straightforward and based on appearance. Your clinician may perform a simple eye examination and, where necessary, request blood tests to rule out bleeding disorders or hypertension.
Treatment options
Observation
Most cases resolve without intervention over several weeks as the blood is gradually reabsorbed.
Symptom Relief
If you experience mild irritation or itching, lubricating eye drops or soothing ointments may offer relief.
There is no need for surgical or invasive procedures, as the condition is benign and self-limiting.
