Dear rvelasco001, Thanks for the question. The cause bloodvessel bursting in the eye is commonly accidental trauma,
hypertension, severe
cough or any activities that ends to raise the blood pressure suddenly even if for a brief while. It is known as sub conjunctival hemmorrhage, which by itself has a benign course and will clear up within 3-4 weeks, but what is important is that the underlying cause such as hypertension or cough or any other treatable cause has to be identified and treated otherwise there will be recurrence.
