A subconjunctival hemorrhage occurs when a tiny blood vessel breaks just underneath the clear surface of your eye (conjunctiva). The most obvious sign of a subconjunctival hemorrhage is a bright red patch on the white (sclera) of your eye. If you believe you’ve suffered an ocular hemorrhage, it is very important to see an eye doctor for a comprehensive eye exam.
A subconjunctival hemorrhage usually is benign, causing no vision problems or significant eye discomfort despite its conspicuous appearance. Your only discomfort may be a scratchy feeling on the surface of your eye.
Subconjunctival hemorrhage often occurs without any obvious harm to your eye, or it may be the result of a strong sneeze or cough that caused a blood vessel to break.
Although it is not always possible to identify the source of the problem, some potential causes of subconjunctival hemorrhage include eye trauma, a sudden increase in blood pressure and certain blood thinning medications such as aspirin or warfarin.
You don't need any specific treatment for a subconjunctival hemorrhage. You may want to use eye drops or artificial tears to soothe any scratchy feeling you have in your eye.
Beyond that, the blood in your eye will absorb within about one to two weeks, and you'll need no further treatment.
