We studied 20 patients with uncontrolled symmetric glaucoma who had undergone bilateral trabeculectomy after having received the same medical or laser treatment to both eyes. In each patient, the techniques and suture material used in the two eyes were identical, and the surgeon was the same. The only variable was the type of conjunctival flap used: one eye received a limbal-based flap and the other a fornix-based flap. These patients were followed up from three to 13 months (median, 8.5 months). There was no difference between the two groups in postoperative anterior chamber depth, intraocular pressure control, occurrence of hyphema, size and shape of the bleb, or the rate of complications. The fornix- and limbal-based conjunctival flaps in trabeculectomy were found to yield comparable results in terms of safety and short-term efficacy of pressure control.
我们研究了20例未得到控制的对称性青光眼患者，这些患者双眼接受了相同的药物或激光治疗后均接受了双侧小梁切除术。在每例患者中，双眼所采用的技术和缝合材料均相同，且手术医生也相同。唯一的变量是所使用的结膜瓣类型：一只眼采用角膜缘结膜瓣，另一只眼采用穹窿部结膜瓣。这些患者的随访时间为3至13个月（中位数为8.5个月）。两组在术后前房深度、眼压控制、前房积血的发生、滤过泡的大小和形状或并发症发生率方面均无差异。结果发现，就小梁切除术中穹窿部和角膜缘结膜瓣在眼压控制的安全性和短期疗效而言，二者效果相当。
