摘　　要：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.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.
