原发性闭角型青光眼晶状体形态变化的超声诊断价值

目的 评价超声检查晶状体形态在原发性闭角型青光眼(PACG)诊断中的价值.方法 超声检测20例PACG患者和22例正常人为对照组的晶状体中央部和周边部厚度,分析晶状体前表面曲率,研究晶状体在PAOG发生和发展中的病理机制.结果 与对照组比较,PACG组晶状体增厚,前表面曲率增大且相对位置偏前.结论 超声诊断晶状体增厚、前表面曲率变大及相对位置前移为临床诊断提供更为直观的形态学依据.

Value of ultrasound in the diagnosis of lens morphological changes in primary angle-closure glaucoma

Objective To explore the value of ultrasound in the diagnosis of lens' morphological changes in primary angle-closure glaucoma(PACG).Methods Twenty patients and 22 health persons were included in the study.Central thickness and periphery thickness were measured by two-dimensional ultrasound.The parameter of anterior lens surface curvature was analyzed by computer to explore the pathological and physiological mechanism of lens in development of PACG.Results PACG group showed thickened lens,increased anterior surface curvature and relatively forward location compared with control group.Conclusion The morphological changes of PACG include thickened lens,increased anterior surface curvature and relatively forward location.Ultrasonography provides morphological changes for clinical diagnosis of PACG.
