急性闭角型青光眼发作眼与对侧眼解剖参数的比较

目的对照研究急性闭角型青光眼发作眼和对侧眼的角膜中央厚度和前房深度，晶状体厚度和眼轴长度。方法共观察了急性闭角型青光眼75例。眼压控制后每个患者双眼接受A超检查，检查项目包括角膜中央厚度、前房深度、晶状体厚度和眼轴长度。统计分析采用配对t检验。结果急性闭角型青光眼发作眼的平均角膜中央厚度是（576．97±50．93）μm，对侧眼的平均角膜中央厚度为（544．68±33．53）μm（P〈0．001）。另外两组之间的前房深度、晶状体厚度和眼轴长度无差异（P〉0．05）。结论与对侧眼相比，急性闭角型青光眼的角膜中央厚度较厚，可能是发作后遗留的损害。其它眼解剖参数无统计学差异，因此对侧眼也应进行预防治疗。

Anatomy parameters in attack eye of primary acute angle-closure glaucoma patients compared to that of contralateral eye

Objective To campare the central corneal thickness (CCT) between the attack eye and contralateral eye in primary acute angle-closure glaucoma(AACG) patients. Methods About 75 primary acute angle-closure glaucoma patients was observed. We measured the CCT of the both eyes in primary acute angle-closure glaucoma by A scan. Also the ACD, thickness of lens and axis were measured when the IOP was reduced. And paired t test was used to compare the difference. Results The mean CCT of the attacked eye of AACG is (576.97 ±50.93) μm while the mean CCT of the contralateral eye is (544.68 ±33.53)(μm. There is significance in CCT between the attacked eye and the contralateral eye(P < 0. 001). There isn' t significance in ACD, thickness of lens and axis between the two eyes( P >0.05). Conclusions CCT was increased in acute angle-closure glaucoma after the attack compared to the contralateral eye which should be considered during the treatment of the AACG patients.
