We studied the frequency of massive suprachoroidal hemorrhage during and after penetrating keratoplasty. Nine cases of intraoperative or immediately postoperative massive suprachoroidal hemorrhage were identified in 830 consecutive patients (1.08%) undergoing penetrating keratoplasties at the Manhattan Eye, Ear, and Throat Hospital over a 2 1/2-year period. Six of the nine patients had atherosclerotic disease or hypertension, six of nine patients had glaucoma, and eight of nine patients had undergone previous intraocular surgery. Surgery was performed under general anesthesia in 714 patients, and four of these patients (0.56%) suffered hemorrhages. Five of 116 (4.3%) local anesthesia patients experienced expulsive choroidal hemorrhage. The increased resistance to venous outflow associated with retrobulbar anesthetic injection may significantly contribute to the risk of massive suprachoroidal hemorrhage.
我们研究了穿透性角膜移植术中及术后发生大量脉络膜上腔出血的频率。在曼哈顿眼耳喉医院2年半的时间里，对830例连续接受穿透性角膜移植术的患者进行了观察，发现9例术中或术后即刻发生大量脉络膜上腔出血（1.08%）。9例患者中有6例患有动脉粥样硬化疾病或高血压，9例中有6例患有青光眼，9例中有8例曾接受过眼内手术。714例患者在全身麻醉下进行手术，其中4例（0.56%）发生出血。116例局部麻醉患者中有5例（4.3%）发生了脉络膜出血。球后麻醉注射导致的静脉流出阻力增加可能是大量脉络膜上腔出血风险增加的重要原因。
