Sub-Conjunctival Haemorrhage
What is it?
A sub-conjunctival haemorrhage is caused by bleeding underneath the conjunctiva (transparent lining over the white part of the eye).
This condition often looks worse than it really is. Usually it does not threaten your vision and it is not painful or dangerous.
Causes:
- Spontaneous/unknown cause
- Physical trauma to the eye
- Violent coughing, sneezing or vomiting
- High blood pressure
- Medications such as aspirin and warfarin that thin the blood and therefore increase the risk of bleeding
Treatment
In general, no treatment is required. The redness may spread and go yellow before disappearing completely from the eye. This can take up to several weeks.
If the eye is uncomfortable or gritty, lubricant drops or ointment may be used. These are available over the counter at your local pharmacy.
Please consult your family doctor if your blood pressure is elevated, particularly if you have experienced repeated sub-conjunctival haemorrhage.
