单眼先天性白内障患者双眼轴长比较分析

A comparison between the axial length of congenital cataract and control eyes

目的 探讨单眼先天性白内障形觉剥夺时间与眼轴的相关性。方法 采用法国BiovisionA型超声仪对32例单眼发病的先天性白内障眼和对侧眼的眼轴进行测量，并进行对比分析，观察形觉剥夺时间与眼轴增长的相关性。结果 先天性白内障眼较对侧眼的眼轴增长，具有统计学意义（P〈0.01）；眼轴增长值与先天性白内障眼形觉剥夺时间存在正相关关系。结论 尽早去除先天性白内障所造成的形觉剥夺，恢复视觉正常环境，有利于预防眼轴增长等眼球发育异常所致的视觉功能异常。

Objective To study the relationship between the form deprivation of congenital cataract and axial oculi. Methods Bilateral axial lengths in 32 cases of unilateral congenital cataract were measured with A-scan ultrasonography, axial lengths of bilateral eyes were compared, study the relationship between the form deprivation of congenital cataract and axial oculi. Results There was significant difference between the axial length of congenital cataract and control eyes.（P〈0.01）Axis oculi and deprivation of congenital cataract have positive correlation. Conclusion Eliminating form deprivation earlier due to congenital cataracts is beneficial to maintain and restore a normal visual environment during the sensitive period of visual development.
