弱视训练对屈光不正性弱视儿童弱视眼调节功能的影响

Effect of amblyopia training in regulating the amblyopic eye in children with ametropic amblyopia

目的:探讨弱视训练对屈光不正性弱视儿童患眼调节功能的影响。方法:对2012年3月~2014年2月于我院行弱视训练治疗的屈光不正性弱视儿童50例(弱视组,共计90眼)病历资料进行回顾分析,记录患儿临床疗效及组内不同弱视严重程度患儿提高1行LogMAR视力所需的平均时间,及儿童眼调节功能指标检测结果差异;并与同期来院体检的视力正常儿童36例(对照组,共计72眼)进行对照观察。结果:弱视组内重度弱视患儿提高1行LogMAR视力所需的平均时间最短,其次为中度弱视患儿,轻度弱视患儿提高1行LogMAR视力所需的平均时间最长,各亚组间比较差异均具统计学意义(P<0.05);治疗前后,弱视组患儿患眼调节幅度和调节灵活度均显著低于对照组儿童,调节滞后量则明显高于对照组儿童(P<0.05)。治疗3个月后,弱视组各患儿患眼调节幅度及调节灵活度均较治疗前明显提高,且轻、中度弱视>重度弱视(P<0.05),患眼调节滞后量则明显降低,且轻、中度弱视<重度弱视(P<0.05)。结论:对屈光不正性弱视儿童予以弱视训练,能有效改善其患眼调节功能,对患儿预后恢复有利。

Objective：To explore the effect of amblyopia training in regulating the amblyopic eye in children with ametropic amblyopia.Methods：A total of 50 children with ametropic amblyopia who were admitted in our hospital from March,2012 to February,2014 for amblyopia training were included in the study and served as the amblyopia group（n=90）.The clinical efficacy and average time to enhance 1 line LogMAR vision in children with different degrees of amblyopia were recorded.The regulatory function indicators of amblyopic eye were detected.A total of 36 children with normal visions who came forphysical examinations at the same stage were served as the control group（n=72）.Results：The average time to enhance 1line LogMAR vision for children with severe amblyopia in the amblyopia group was the shortest,secondly was the moderate amblyopia children,while the average time for children with mild amblyopia was the longest,and the comparison among each group was statistically significant（P〈0.05）.The accommodation amplitude and accommodation flexibility before and after treatment in the amblyopia group were significantly lower than those in the control group（P〈0.05）,while the accommodation lag was significantly higher than that in the control group（P〈0.05）.The accommodation amplitude and accommodation flexibility 3months after treatment in the amblyopia group were significantly elevated,and those in children with mild and moderate amblyopia were significantly higher than those in children with severe amblyopia（P〈0.05）,while the accommodation lag was significantly reduced,and that in children with mild and moderate amblyopia was significantly lower than that in children with severe amblyopia（P〈0.05）.Conclusions：Amblyopia training for children with ametropic amblyopia can effectively improve the regulatory function,and is beneficial for the recovery.
