目的探讨屈光不正性弱视儿童屈光度变化的规律。方法对197例(370眼)屈光不正性弱视儿童每年进行一次屈光检查,连续4年以上,将逐年屈光度的数据作比较,并进行屈光度与观察期的直线回归分析。结果远视屈光度逐年减少,其平均值与观察期存在回归关系;近视屈光度逐年增加,其平均值与观察期也存在回归关系;散光度数保持不变或略有增减。结论屈光不正性弱视儿童的屈光度随着年龄的增长,有远视度数逐年减少,近视度数逐年增加的趋势,而散光度数则基本保持不变。
Objective To study the changes of refractive error in children with refractive amblyopia. Methods A total of 197 eyes (370 eyes) with refractive amblyopia were examined annually for more than four years. The data of annual refraction were compared and linear regression analysis was performed between diopter and observation period. Results The refractive power of myopia decreased year by year, and the average value of the myopia had a regression relationship with the observation period. The refraction of myopia increased year by year. The average value of the myopia also had a regression relationship with the observation period. The degree of astigmatism remained unchanged or slightly increased or decreased. Conclusions The refractive power of children with ametropic amblyopia increases with age, the number of myopia decreases year by year, the number of myopia tends to increase year by year, while the number of astigmatism remains basically unchanged.
