title: Preoperative prediction of hyphemas.
abstract: In a prospective study, 139 patients undergoing cataract extraction were evaluated preoperatively with a panel of coagulation studies: prothrombin time, partial thromboplastin time, platelet count, and total bleeding time. Patients were monitored postoperatively for the presence of a hyphema which was then correlated with the test results. There was an overall incidence of 10.8% hyphemas in the population, and a statistically significant correlation was revealed with abnormal test results only if all the tests were considered together.
