Subconjuctival Hemorrhage
The
conjuntiva is the clear membrane that covers the white part
of the eye, or sclera. It protects and lubricates
the eyeball. The conjuctiva contains many small, rather fragile
blood vessels. Rupture of one of these small vessels or
capillaries results in a subconjunctival hemorrhage. This
appears as a sharply-outlined, bright red spot on the white of
the eye.
Most of the
time no symptoms accompany subconjunctival hemorrhages; however,
some patients complain of a sharp pain when the hemorrhage
begins. Many people become alarmed by the sudden onset of this
common problem, even though it is not associated with any
diseases that cause vision loss. The hemorrhage tends to fade
over the following two or three weeks and clears last in the
area next to the colored part of the eye (iris).
Most of the
time an obvious cause is not found. Only rarely is the
condition ever associated with high blood pressure or other
bleeding problems. Often it is discovered on awakening.
Occasionally it occurs due to sneezing, coughing, straining or
eye rubbing.
No treatment
is needed. Subconjunctival hemorrhages may move or spread and
look worse before they become better, but they will eventually
clear. |
