- The conjunctiva contains many small, fragile blood vessels that are easily ruptured or broken. When this happens, blood leaks into the space between the conjunctiva and sclera.
- A sub conjunctival haemorrhage also known as hyposphagma is bleeding underneath the conjunctiva.
- Eye trauma
- Congenital or acquired (coagulation disorder)
- Diving accidents
- Head injury
- Severe hypertension
- Acute haemorrhagic conjunctivitis
- Increased venous pressure (e.g.-straining, vomiting, choking, or coughing)
- In the absence of infection or significant trauma sub conjunctival haemorrhage is typically a self-limiting condition that requires no treatment.
- The elective use of aspirin & NSAIDs is typically discouraged
- Artificial tears may be applied four to six times a day
