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.
