目的 探讨部分眼解剖因素与青光眼小梁切除术后并发持续性浅前房之间的关系.方法 术前A超测量拟接受小梁切除手术的原发性闭角型青光眼患者的中央前房深度(D)、晶状体厚度(L)和眼轴长度(A),并计算前房深度和轴长的积与晶状体厚度的比值(D×ML).根据Spaeth分类法和术后前房的形成时间,如患者Ⅲ度浅前房持续1d以上,Ⅱ度浅前房持续5～7d以上需手术介入者,归入浅前房组;其他患者术后前房在7d之内恢复正常者则归入正常组,统计分析两组上述参数的差异.结果 浅前房组的眼轴长度较正常组短(P<0.01),而中央前房深度较正常组深(P<0.05).晶状体厚度较正常组薄(P<0.01),参数D×A/L两组则差异无统计学意义(P>0.05).结论 在上述原发性闭角型青光眼的危险因素中,只有眼轴长度短与持续性浅前房的发生有关,提示术前进行眼轴长度的测量可部分预测小梁切除术后持续性浅前房的发生.
目的 探討部分眼解剖因素與青光眼小樑切除術後併髮持續性淺前房之間的關繫.方法 術前A超測量擬接受小樑切除手術的原髮性閉角型青光眼患者的中央前房深度(D)、晶狀體厚度(L)和眼軸長度(A),併計算前房深度和軸長的積與晶狀體厚度的比值(D×ML).根據Spaeth分類法和術後前房的形成時間,如患者Ⅲ度淺前房持續1d以上,Ⅱ度淺前房持續5～7d以上需手術介入者,歸入淺前房組;其他患者術後前房在7d之內恢複正常者則歸入正常組,統計分析兩組上述參數的差異.結果 淺前房組的眼軸長度較正常組短(P<0.01),而中央前房深度較正常組深(P<0.05).晶狀體厚度較正常組薄(P<0.01),參數D×A/L兩組則差異無統計學意義(P>0.05).結論 在上述原髮性閉角型青光眼的危險因素中,隻有眼軸長度短與持續性淺前房的髮生有關,提示術前進行眼軸長度的測量可部分預測小樑切除術後持續性淺前房的髮生.

Objective To elucidate the relationships between some ocular anatomical parameters and occurrence of sustained shallow anterior chamber after trabeculctomy.Methods The central anterior chamber depth (D), lens thickness (L), axial length(A) of primary angle closure glaucoma sufferers were measured before accepting trabeculectomy and ratio of the product of D and A to L (D*A/L) was calculated.According to postoperative observation, the patients, if shallow anterior chamber Ⅲover 1 day or Ⅱ lasting for 5-7 days and a surgical intervention being needed, fell into shallow anterior chamber group and the rest with anterior chamber recovery within 5-7 days into normal recovery group.Results Compared with normal recovery group,shallow anterior chamber group possesses a shorter axial length (P<0.01) but a deeper central anterior chamber depth (P<0.05, >0.01) and a thinner lens thickness (P<0.01) while no significant difference was found in D*A/L parameter (P>0.05).Conclusion Among those risky factors to primary angle closure glaucoma,only the shorter axial length is found a possible correlation to the occurrence of sustained shallow anterior chamber.It would partially predict the incidence of shallow anterior chamber and attract attention in advance to measure the axial length preoperatively when performing trabculectomy to patients.
