对８４例（１０４眼）原发性青光眼，首次成功滤过手术眼术后的前房深度观察，２３眼于手术结束时用平衡盐液（ＢＳＳ）形成前房，术后发生浅前房２眼占６．１％；７１眼令其自然恢复，术后发生浅前房２５眼占３５．２％。两组术后浅前房的发生率差异有高度显著性（Ｐ＜０．０１）。表明术中形成前房可明显降低滤过术后浅前房的发生率。闭角型较开角型青光眼术后浅前房的发生率高（Ｐ＜０．０５）；小梁切除术和巩膜瓣下咬切术术后浅前房的发生率无显著差异（Ｐ＞０．０５）。手术结束时用平衡盐液形成前房可以预防术后前房延缓形成，从而避免浅前房引起的并发症。
For 84 cases (104 eyes) of primary glaucoma, the depth of anterior chamber was observed after the first successful filtering surgery, and 23 eyes were formed with balanced salt solution (BSS) at the end of surgery. The anterior chamber occurred after operation Eyes accounted for 6.1%; 71 eyes make it natural recovery, 25 cases of shallow anterior chamber occurred after 35.2%. The incidence of postoperative shallow anterior chamber was highly significant (P <0.01). Show that the formation of anterior chamber surgery can significantly reduce the incidence of shallow anterior chamber after filtration. The incidence of shallow anterior chamber was significantly higher in patients with angle-closure open-angle glaucoma (P <0.05). There was no significant difference in the incidence of shallow anterior chamber between trabeculectomy and scleral buckling (P> 0.05). The formation of the anterior chamber with balanced salt solution at the end of surgery can prevent postoperative anterior chamber retardation, thus avoiding the complications caused by the shallow anterior chamber.
