白内障术中房水迷流综合征

Fluid misdirection syndrome during cataract surgery

白内障术中房水迷流综合征是白内障术中罕见且严重的并发症,其特点为眼压突然升高、虹膜前移、前房变浅,且排除脉络膜上腔出血。其病理机制为液体通过睫状带区域进入玻璃体与晶状体后囊之间的腔隙并产生聚集。危险因素有高灌注压、晶状体悬韧带脆弱等。充分术前评估以及精细手术操作是预防白内障术中房水迷流的重要方式。目前普遍使用经睫状体平坦部玻璃体腔穿刺吸取液体治疗。

Fluid misdirection syndrome during cataract surgery is a rare and serious complication,characterized by an immediate increase in intraocular pressure,iris anterior movement and shallow anterior chamber,excluding iris hyphema.The pathological mechanism involves the accumulation of fluid between the posterior chamber and the anterior hyaloid membrane.Its risk factors include high intraocular pressure and thinning of the lens capsule.To prevent fluid misdirection syndrome,adequate assessment and meticulous operation during surgery are important.Currently,pars-plana fluid aspiration is the primary treatment method for this condition.
