This is an extreme form of
hyphemia in which the
bleeding in the
eye is so bad that the entire
eyeball turns black or dark brown from
blood clots. Thus, the eye resembles a miniature black
billiard ball. This condition is generally caused by a
severe blow to the
head or a direct blow to the
eye (such as by being struck by a
baseball or
racquetball, two common ways people end up with this condition).
This condition almost always requires surgery to correct.
