Subconjunctival Hemorrhage

A subconjuctival hemorrhage is a common disorder that usually occurs spontaneously in only one eye and may affect any age group. Its sudden onset and bright red appearance can be very alarming. The hemorrhage is caused by the rupture of a small blood vessel in the conjunctiva, which lies over the sclera (white part of your eye). It is very much like a bruise; but while your skin is translucent, allowing a bluish appearance, your conjuctiva is transparent, allowing the redness of the blood to show through. The subconjunctival hemorrhage appears as a flat, deep-red hemorrhage under the conjunctiva, and may be sufficiently severe to cause a traumatic “bag of blood” to protrude over the lid margin.

This hemorrhage is sometimes preceded by a bout of severe coughing or sneezing. It may be induced by a major or minor trauma to the eye; or it may just appear as a spontaneous hemorrhage. In rare instances hemorrhages occur in both eyes and are recurrent. In this case, the possibility of blood disease should be examined. Occasionally, bacterial or viral infections my be associated, accompanied by discomfort and discharge.

In the absence of infection or any trauma to the eye, treatment is unnecessary. The hemorrhage usually absorbs in two weeks with no therapy. Warm compresses generally will have it cleared up in 14 days. Blood thinners, including aspirin, may influence this situation. If it reoccurs, discuss this with your general practitioner.   If subconjunctival hemorrhage occurs and you have any questions, please feel free to get in touch with us.
