【摘要】 爆发性脉络膜上腔出血(SCH)是少见但严重威胁视力的内眼手术并发症。尽管治疗方法不断进展,视力预后仍然较差。该病的临床表现较为典型,病因及发病机制尚未明确,术中眼部及全身的多种因素均可能诱发爆发性SCH。术中应急处理及二次手术时间的选择十分重要。二次手术主要包括巩膜切开引流术、玻璃体切割术、重组纤溶酶原激活剂辅助手术等,但最好的治疗方法仍然存在争议。此外对于较小范围的爆发性SCH,药物治疗可以取得一定疗效。该文就爆发性SCH的临床表现、发病机制、易患因素及治疗方法进行综述。更多还原

【Abstract】 Expulsive suprachoroidal hemorrhage(SCH) is a rare complication of intraocular surgery,which severely threatens the visual acuity.In spite of continuous progression of therapeutic approaches,the clinical prognosis of visual acuity remains relatively poor.SCH possesses typical clinical manifestations,whereas the etiology and pathogenesis of SCH remains elusive.Intraoperative ocular and systemic factors probably induce the incidence of SCH.Intraoperative emergent management and the timing of secondary surgery are of great significance.Secondary surgeries mainly include scleral incision and drainage,vitrectomy,recombinant tissue plasminogen activator-assisted surgery,etc.However,the optimal treatment is still controversial.Medication therapy yields certain clinical efficacy in the management of relatively slight SCH.This article summarizes the clinical manifestations,pathogenesis,susceptible factors and therapeutic methods of SCH.更多还原
