We reviewed the charts of 500 patients who underwent filtration procedures and found ten patients who developed postoperative suprachoroidal hemorrhage (PSCH) following surgery. The incidence (2% overall) is especially high in those patients who were aphakic (6.6%) or who had high myopia (10%). Nine patients developed PSCH within the first four postoperative days. Pain, nausea, and vomiting were common presenting symptoms of PSCH although not invariably present. Postoperative suprachoroidal hemorrhage is related to prolonged hypotonia and inflammation; prevention centers on proper case selection and on avoiding a precipitous rise in postoperative intravascular pressure. Initial treatment consisted of anterior chamber reformation and drainage of suprachoroidal blood, often followed by vitrectomy and scleral buckling procedures. Four eyes (40%) obtained final visual acuities of 20/200 or better, four (40%) were reduced to counting fingers or hand motions, and two (20%) lost all light perception.
我们查阅了500例行滤过手术患者的病历，发现有10例患者术后发生脉络膜上腔出血（PSCH）。总体发生率为2%，在无晶状体患者（6.6%）或高度近视患者（10%）中尤其高。9例患者在术后头4天内发生PSCH。疼痛、恶心和呕吐是PSCH常见的症状表现，但并非总是出现。术后脉络膜上腔出血与持续性低眼压和炎症有关；预防的关键在于合理选择病例以及避免术后血管内压力急剧升高。初始治疗包括前房重建和脉络膜上腔血液引流，通常随后进行玻璃体切除术和巩膜扣带术。4只眼（40%）最终视力达到20/200或更好，4只眼（40%）视力降至数指或手动，2只眼（20%）丧失所有光感。
