白内障超声乳化术后晚期囊袋阻滞综合征临床分析

Etiopathogenesis of late capsular block syndrome after cataract-phacoemulsifi cation

目的 探讨白内障超声乳化联合人工晶状体植入术后晚期囊袋阻滞综合征（capsular block syndrome,CBS）的临床表现、发生机制及治疗方法。方法 回顾性分析解放军总医院2012年6月-2013年6月收治的白内障超声乳化人工晶状体植入术后晚期CBS患者5例（5只眼）,均采用囊袋松解及囊袋内液体吸除术治疗。结果 5例发病时间为术后1-6年,平均术后3.6年,均表现为前囊口阻滞、人工晶状体前移位、囊袋皱缩,后囊扩张,其中2例囊袋内有乳白色液体积聚。5例均行囊袋松解及囊袋内液体吸除术治疗,术后裸眼视力不同幅度提高。结论 行囊袋松解及囊袋内液体吸除术是治疗术后晚期CBS的可靠方法。

Objective To investigate the clinical manifestation, pathogenesis and therapy of later capsular block syndrome （CBS） after cataract-phacoemulsification with intraocular lens （IOL） implantation. Methods Five patients （5 eyes） admitted to our hospital from June 2012 to June 2013 were retrospectively analyzed, and they all took the treatment with capsule of lens and capsular liquid ~ Results Five eyes of late postoperative CBS all had anterior capsular opening block, IOL moving forward, and posterior capsule expansion, which occurred in 1 year to 6 years （average, 3.6 years） after cataract-phacoemulsification with 1OL implantation, and 2 eyes were filled with milky liquid in the capsule. UCVA （naked vision） improved in all patients after treatment with capsule release and aspiration of the capsular liquid. Conclusion Capsule release and aspiration of the capsular liquid are the effective treatment methods for late postoperative CBS.
