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
, two common ways people end up with this condition).
This condition almost always requires surgery to correct.
