再出血是钝伤性前房积血常见而严重的并发症,其发生率为5—38%。多数学者认为再出血与房水中存在纤维蛋白溶解活性有关,在血管的连续性及完整性恢复前,如果破裂血管的血栓溶解或退缩,即可发生再出血。由于再出血的量往往比初次积血量多,且常伴有青光眼、角膜血染、虹膜前、后粘连等并发症,病人的手术机会增加,视力预后变差,因此,预防再出血是治疗钝伤性前房积血的重要内容。为了确定prednisone及EACA 在预防再出血中的作用,我们对钝 Rebleeding is a common and serious complication of blunt traumatic hyphema, with an incidence of 5-38%. Most scholars believe that rebleeding is associated with the presence of fibrinolytic activity in aqueous humor. Re-bleeding may occur if the thrombosis of the ruptured vessel is dissolved or withdrawn before the continuity and integrity of the blood vessel is restored. Because the amount of rebleeding is often more than the first volume of hemorrhage, and often accompanied by glaucoma, corneal blood stained, pre-iris adhesions and other complications, the patient’s chance of surgery increased, the prognosis of vision worse, therefore, the prevention of rebleeding is the treatment Blunt traumatic hyphema an important part. In order to determine the role of prednisone and EACA in the prevention of rebleeding, we blunt
