目的 观察冻干人羊膜在抗青光眼手术中的防粘连作用。方法 对 10例 (13只眼 )难治性青光眼行小梁切除术后 ,在巩膜瓣及结膜瓣下植入冻干羊膜。结果 术后第 1天结膜下滤过泡扁平 ,前房形成良好。术后 3个月结膜下滤过泡无明显变化。术后第 1天及术后 3个月平均眼压为 14 .3± 2 .5 mm Hg及 15 .9± 1.8m m Hg,与术前相比有显著性差异 (P <0 .0 0 1)。结论 冻干羊膜具有防粘连、保持滤过道通畅的作用。
Objective To observe the anti-adhesion effect of lyophilized human amniotic membrane in anti-glaucoma surgery. Methods Ten patients (13 eyes) with intractable glaucoma underwent trabeculectomy, and the amniotic membrane was implanted under scleral flap and conjunctival flap. Results On the first postoperative day, the conjunctival perforation was flattened and the anterior chamber was well formed. There was no significant change in conjunctival filtration bleb after 3 months. The mean intraocular pressure (IOP) at the first postoperative day and the third postoperative month were 14.3 ± 2.5 mm Hg and 15.9 ± 1.8 mm Hg, which were significantly different from those before operation (P <0.01) ). Conclusion Freeze-dried amniotic membrane with anti-adhesion, keep the filtration tract unobstructed role.
