  • 简介:目的分析剥脱综合征(ES)患者和正常人眼轴及中央前房深度与眼压的相关性。方法2010年1月~2012年1月间来本院就诊的Es患者106例(106眼)、正常人69例(69眼),均为维吾尔族。观察Es眼和非ES眼眼轴长度、中央前房深度及眼压有无差异,分析眼轴及中央前房深度与眼压的相关性。结果ES患者眼轴长度为(22.89±0.91)mm,正常人眼轴长度为(23.12±0.97)mm,差异无统计学意义(P=0.12);ES患者前房深度为(2.84±0.41)mm,正常人前房深度为(2.93±0.39)mm,差异无统计学意义(P=0.14);ES患者眼压为(26.72±15.70)mmHg(1mmHg=0.133kPa),正常人眼压为(14.39±2.19)mmHg,差异有统计学意义(P=0.00)。Es患者眼轴与眼压具有相关性(r=-0.412,P=0.00);正常人眼轴与眼压不具有相关性(r=-0.102,P=0.405)。ES患者中央前房深度与眼压具有相关性(r=-0.33,P=0.001);正常人中央前房深度与眼压不具有相关性(r=-0.102,P=0.406)。结论维吾尔族ES患者的眼压较正常人高,其眼轴及中央前房深度与眼压具有负相关性。(中国眼耳鼻喉科杂志,2013,13:170—172)
