The detrimental effect of aspirin on hyphema rebleed.

One hundred ninety-five cases of traumatic hyphema admitted to 2 medical centers over an 8 year period were studied in terms of factors effecting the rebleeding rate. It was found that aspirin given for analgesia had a detrimental effect on the rebleeding rate, and that dilating the iris offered some protection against this complication. This report is the second one to show association of higher rebleeding rate and aspirin.
