Subconjunctival hemorrhage
Subconjunctival bleeding, also known as subconjunctival hemorrhage, is bleeding underneath the conjunctiva. The conjunctiva contains many small, fragile blood vesselsthat are easily ruptured or broken. When this happens, blood leaks into the space between the conjunctiva and sclera. Such a hemorrhage may be caused by a sudden or severe sneeze or cough, or due to high blood pressure or as a side effect of blood thinners such as aspirin or warfarin. It may also be caused by heavy lifting, vomiting, or even rubbing one's eyes too roughly. In other cases, it may result from being choked or from straining due to constipation. Also, it can result as a minor post-operative complication in eye surgeries such as LASIK Although its appearance may be alarming, in general a subconjunctival bleeding is a painless and harmless condition
