Application of hyaluronan in the treatment of shallow anterior chamber

目的探讨黏弹剂透明质酸钠(hyaluronan,HA)在治疗浅前房中的作用。方法对26例(26眼)浅前房患者行前房注入HA,观察术后角膜、视力的变化,前房的形成及眼压的改变。结果术后第1天,24眼眼压控制在21mmHg(1mmHg=0.133kPa)以下,2眼大于21mmHg,经药物治疗后均控制在21mmHg以下;26眼前房形成良好,角膜逐渐恢复透明;术后1个月,24眼最佳矫正视力提高。结论黏弹剂的应用促使前房恢复,提高手术成功率。

Objective To investigate the role of hyaluronan（HA） in the treatment of shallow anterior chamber. Methods HA agents were filled into the shallow anterior chambers caused by different reasons in 26 cases （26 eyes）. The anterior chamber formation and the changes of cornea, vision and the intraocular pressure and were observed. Results One day after the operation, the intraocular pressure was below 21 mm Hg （ 1 mm Hg = 0. 133 kPa） in 24 eyes and higher in 2 eyes which were controlled later by drugs. Anterior chambers were well formed in 26 eyes with the corneal transparency gradually restored. One month after the operation the best-corrected visual acuity improved in 24 cases （24 eyes）. Conclusions Application of hyaluronan was helpful restore the anterior chamber and to improve the success of surgery.
