无前房或浅前房是青光眼滤过性手术后早期主要并发症之一。人们已经提出了许多方法以减少它的发生,例如使用青光眼罩紧密闭合巩膜瓣、前房内注入空气或粘稠剂等。另一并发症是角膜内皮细胞丧失。目前透明质酸钠(HA),已广泛用于保护角膜内皮细胞。据报道,在青光眼滤过性手术中应用HA的优点有术后可减少低眼压和无前房的发生率,视力较好;滤枕结疤轻,很少形成虹膜周边前粘连,术后用药量少。至关重要的是粘稠剂在术中给予的时机。正像Wand(1988)提出的,为防止术后无前房,关键是
No anterior chamber or shallow anterior chamber glaucoma filtration surgery is one of the main complications after surgery. Many methods have been proposed to reduce its occurrence, such as the use of glaucoma to close the scleral flap, the anterior chamber to inject air or viscous agents and so on. Another complication is the loss of corneal endothelial cells. Currently sodium hyaluronate (HA) has been widely used to protect corneal endothelial cells. It is reported that the advantages of the application of HA in glaucoma filtration surgery postoperative can reduce the incidence of low intraocular pressure and no anterior chamber, better visual acuity; filter pillow scar light, rarely form the iris peripheral adhesions, postoperative Small amount of medication. It is crucial that the viscous agent be given intraoperatively. As Wand (1988) put it, the key is to prevent anterior chamber after surgery
