To evaluate the interaction of risk factors for expulsive hemorrhage, we evaluated 3 cases of expulsive hemorrhage and 2 of acute intraoperative choroidal effusion that occurred at the University of Tsukuba Hospital over a 16-year-period and investigated the common findings in these 5 cases. We also selected randomly 500 cataractous cases operated at the University of Tsukuba Hospital and investigated the probabilities of risk factors for expulsive hemorrhage in these control cases. The 5 affected patients exhibited more than four risk factors of expulsive hemorrhage. The probability of more than four risk factors being involved in any cataract operation was approximately 0.33% (0.17 approximately 0.67%; 95% confidence interval). The incidence of expulsive hemorrhage at our hospital was approximately 0.2%, which is similar to the probability rate. Thus, we concluded that the development of expulsive hemorrhage was proved to be related to an accumulation of the risk factors for expulsive hemorrhage.
为评估驱逐性出血的危险因素之间的相互作用，我们评估了筑波大学医院在16年期间发生的3例驱逐性出血和2例急性术中脉络膜积液病例，并调查了这5例病例中的共同发现。我们还随机选择了在筑波大学医院接受手术的500例白内障病例，并调查了这些对照病例中发生驱逐性出血的危险因素概率。5例受影响患者表现出超过四种驱逐性出血的危险因素。在任何白内障手术中涉及超过四种危险因素的概率约为0.33%（0.17至0.67%；95%置信区间）。我院驱逐性出血的发生率约为0.2%，与该概率相似。因此，我们得出结论，驱逐性出血的发生被证明与驱逐性出血危险因素的积累有关。
