One hundred and twenty-seven cases of traumatic hyphema are reviewed and discussed according to a definite system of grading. Grade iii hyphemas have definitely a poorer prognosis than Grade ii and Grade i hyphemas. Rebleeding occurs more frequently when there is a delay in treatment but does not appear to affect the outcome of a traumatic hyphema. Blood staining of the cornea could be avoided by an adequate treatment started immediately after the trauma, thus decreasing the percentage of blindness following a traumatic hyphema.
