摘要
目的分析白内障晶状体超声乳化术中发生脉络膜下爆发性出血（SEH）的原因和治疗效果。方法对2012年1月至2014年12月6例（6眼）超声乳化术中及术后发生脉络膜下爆发性出血的临床资料进行回顾性分析。患者均伴有高血压病，3例伴有高度近视。结果6例中出血发生于术中者4例，发生于术后者2例。经保守治疗和手术治疗，随访3～29个月，平均（15．7±10．5）个月。治疗后视力4例为0．25、0．3、0．8、0．9。原有黄斑变性或视网膜脱离的2例，视力未恢复。所有患者眼压正常。眼球切开后眼压突然降低，使眼内外压力差过大，引起脉络膜血管破裂是SEH的主要原因。高血压、高度近视、高血糖及术中过度紧张与术中发生SEH相关。结论白内障术中及时发现与治疗SEH，可以保留其部分视力，挽救患者的眼球。
Objective To analyze the cause and the treatment efficacy of subchoroidal expulsive hemorrhage（SEH） in phacoemulsification. Methods Six eyes of 6 cases of subchoroidal expulsive hemorrhage from Jan. 2012 to Dec. 2014 dining and after phacoemulsification were analzed retrospectively. All cases suffered from hypertension and 3 cases of high myopia. Results All cases received conservative treatment and surgery. SEH occurred during the surgery in 4 cases and 2 cases after surgery. The follow-up time was 3-29 months, average （15.7 ± 10.5） months. After treatment the visual acuity of 4 cases was 0.25,0.3,0.8,0.9. The visual acuity of macular degeneration or retinal detachment wasn＇ t improved in 2 cases. After treatment IOP were normal. IOP was suddenly reduced after eye incision, so that the internal and external pressure difference was too large, which was the main cause of SEH. Hypertension, high myopia, hyperglycemia and intraoperative tension were associated with introperative SEH. Conclusion Early diagnosis and treatment of SEH during phacoemulsification can maintain the eyeball integrity and save partial sight.
