Traumatic hyphema. Failure of steroids to alter its course: a double-blind prospective study.

Forty-three patients with traumatic hypema were studied prospectively in a controlled, double-blind study. Twenty-three patients received prednisone and 20 received a lactose placebo. Secondary hemorrhages occurred in 16% of all patients. There was no significant difference in the incidence of secondary hemorrhage between the two groups (P = .85). There is no evidence that prednisone (40 mg/day) decreases the incidence of secondary hemorrhage. There was no significant difference in final visual acuities between the two groups. Patients with initially larger hyphemas do not appear to have worse final visual acuities. Hyphemas without secondary hemorrhage had a uniformly good prognosis. Although final visual acuities were worse in eyes with secondary hemorrhage, associated ocular injuries rather than blood-related complications accounted for the decreased visual acuity.
