A burst blood vessel on the eye usually describes a subconjunctival haemorrhage, where a tiny vessel leaks under the conjunctiva. It appears as a sharply outlined red patch.
Why Vessels Burst
Sudden increases in venous pressure from coughing, sneezing, lifting, or vomiting can rupture fragile vessels. Local trauma, vigorous rubbing, contact lens insertion, high blood pressure, blood thinners, and clotting disorders also contribute.
- Most events are isolated and benign
- Recurrent haemorrhages warrant investigation of systemic health
- Severe trauma may damage deeper structures beyond the visible bleed
- Older age and vascular disease make subconjunctival vessels more fragile
Course and Care
The blood is gradually reabsorbed over one to three weeks without specific therapy. Assessment ensures there is no more serious underlying injury or systemic cause.
- Cold compresses early on may limit spread, while warm compresses later can aid resorption
- Artificial tears reduce minor irritation
- Patients on anticoagulants should inform their doctor about recurrent bleeds
- Eye protection helps prevent trauma-related episodes
