Nine cases of intraoperative expulsive suprachoroidal hemorrhage occurred in a series of 2011 consecutive penetrating keratoplasties (an incidence of 0.45%). In four cases, the complication was directly related to the anesthesia technique. The incidence of hemorrhage was 1.0% in the eyes with preoperative anterior chamber intraocular lenses (IOLs), an incidence significantly higher than for any other associated condition (P < .02). Four of the nine patients recovered a postoperative visual acuity of 20/70 or better. We discuss reasons for the relatively high incidence of hemorrhage during penetrating keratoplasty; its occurrence in relation to the type of anesthesia used, prior intraocular surgery, types of surgery performed together with the penetrating keratoplasty, and the presence of an anterior chamber IOL; and the risks introduced by hemorrhage in a fellow eye and by a previous hemorrhage in the same eye.
在连续2011例穿透性角膜移植术中，发生了9例术中暴发性脉络膜上腔出血（发生率为0.45%）。其中4例并发症与麻醉技术直接相关。术前有前房人工晶状体（IOL）的眼中，出血发生率为1.0%，该发生率显著高于任何其他相关情况（P < 0.02）。9例患者中有4例术后视力恢复到20/70或更好。我们讨论了穿透性角膜移植术中出血发生率相对较高的原因；其发生与所用麻醉类型、既往眼内手术、与穿透性角膜移植术同时进行的手术类型以及前房IOL的存在之间的关系；以及对侧眼出血和同一只眼既往出血所带来的风险。
