目的探讨原发性急性闭角型青光眼术前术后与正常眼的解剖结构差异.方法使用A超对30例(60只眼)原发性急性闭角型青光眼(AACG)术前术后及对照组30例(60只眼)正常眼的解剖结构(包括前房深度、晶状体厚度、玻璃体腔长度、眼轴长度)和角膜直径进行测量,同时计算相对晶状体位置及晶状体厚度/眼轴长度系数,各项均值进行对比分析(t检验).结果 AACG术前术后与正常眼相比,前房浅、晶状体厚、眼轴短、相对晶状体位置前移、晶状体厚度/眼轴长度系数大,角膜横径较小,以上差异均有显著性(P＜0.05).结论 AACG以浅前房、厚晶状体、眼轴短、角膜横径较小等特点.相对晶状体位置及晶状体厚度/眼轴长度系数可作为AACG早期诊断的指标之一.

Objective To explore the differences in anatomic structures of primary acute angle closure glaucoma (PAACG).Methods sixty eyes of 30 cases of PAACG and 60 eyes of 30 cases of normal eyes were enrolled in the study.For PAACG patients,anatomical structural data were obtained before and after trabeculectomy surgery.Then the results were compared with the data of normal eyes.Observational items included anterior chamber depth,lens thickness,vitreous cavity length,axial length and corneal diameter.The relative location of lens was calculated by the formula (anterior chamber depth + 1/2 lens thickness) over axial length.The coefficient of lens thickness over axial length was calculated and analyzed.Results Compared with normal eyes,PAACG patients had shallower anterior chamber,thicker lens,shorter axial length,forward shifting of lens position,smaller corneal diameter and larger coefficient of lens thickness/axial length.The differences were statistically significant (P ＜ 0.05).Conclusion PAACG patients have shallower anterior Chamber,thicker lens,shorter axial length and smaller corneal diameter.The relative location of lens and coefficient of lens thickness/axial length are the early indicators for PAACG.
