先天性白内障近视发生的危险因素分析

摘要

ObjectiveTo explore the risk factors of myopic occurrence in congenital cataract and to provide scientific basis of preventing myopia．MethodsThe corneal diopter，anterior chamber depth，thickness of lens，axial length of 109 eyes in 83 cases with congenital cataract were measured biologically and their refractive state was also determined．Logistic regression of single factor or multiple factors were used for statistical analysis． ResultsMyopic incident rate was 61.38％ among congenital cataract．The axial length was achief myopic risk factor．The axiall engthi ncreased 1mm，the OR increased 138.699．C onclusionIt is beneficial to eliminating form deprivation from congenital c ataract earlier，keeping or restoring normal visual environment and the prevention of myopia in critical periods of visual development．%目的探讨先天性白内障近视发生的危险因素，提供预防近视的科学依据。方法对83例109只先天性白内障眼球的各屈光因子进行生物学测量，确定其屈光状态，并用Logistic回归的方法进行单因素和多因素分析。结果先天性白内障的近视发生率是61.27%，眼轴长度为近视发生的主要危险因素，OR=138.699。结论尽早去除先天性白内障所造成的形觉剥夺，保持或恢复视觉发育敏感期正常的视觉环境，有利于预防近视的发生。
