目的:评价视知觉训练治疗对弱视儿童视觉表征和双眼视功能的影响。
方法:选取2014-01/2015-12我院眼科门诊收治的94例94眼弱视儿童为研究对象,并按弱视程度进行分组,采用视知觉训练治疗3mo。比较各组临床疗效及治疗前后的知觉水平眼位和差眼视力,并采用Pearson相关系数分析弱视儿童治疗前后差眼视力差值与知觉眼位差值的关系。
结果:轻度弱视儿童临床总有效率高于中、重度弱视儿童(P<0.05),中度弱视儿童与重度弱视儿童临床总有效率比较无差异(P>0.05)。弱视儿童治疗后知觉水平眼位明显低于治疗前(P<0.05); 轻、中、重度弱视患儿治疗后知觉水平眼位均明显降低(P<0.05),轻、中度弱视儿童知觉水平眼位改善幅度较重度弱视患儿明显(P<0.05)。弱视儿童治疗后差眼视力较治疗前明显提升(P<0.05); 轻、中、重度弱视患儿治疗后差眼视力均明显提高(P<0.05),轻、中度弱视儿童差眼视力改善幅度较重度弱视患儿明显(P<0.05)。弱视儿童治疗前后差眼视力差值与知觉眼位差值呈正相关(r=0.371,P<0.001)。
结论:视知觉训练治疗能有效改善弱视儿童视觉表征、双眼视功能,适用于弱视儿童的临床治疗。

[Abstract]
AIM: To evaluate the effects of visual perceptual learning on visual representation and binocular vision function of children with amblyopia.
METHODS: A total of 94 cases(94 eyes)children with amblyopia admitted to the ophthalmology clinic of our hospital from January 2014 to December 2015 were selected for the study and were grouped according to the degrees of amblyopia, and they were given visual perceptual learning for 3mo. The clinical efficacy and perceptual level of eye position and poor visual acuity before and after treatment were compared among groups, and Pearson correlation coefficient was used to analyze the relationship between difference of poor visual acuity and difference of perceptual eye position before and after treatment in children with amblyopia.
RESULTS: The total clinical effective rate of children with mild amblyopia was higher than that of children with moderate or severe amblyopia(P<0.05), and there was no significant difference in the total clinical effective rate between children with moderate amblyopia and children with severe amblyopia(P>0.05). The perception level of eye position after treatment of children with amblyopia was significantly lower than that before treatment(P<0.05). The perception level of eye position after treatment in children with mild, moderate or severe amblyopia was significantly decreased(P<0.05), and the improvement of perception level of eye position in children with mild or moderate amblyopia was more significant than that in children with severe amblyopia(P<0.05). The poor visual acuity of children with amblyopia after treatment was significantly improved compared with that before treatment(P<0.05). The poor visual acuity after treatment in children with mild, moderate or severe amblyopia was significantly improvement(P<0.05), and the improvement of poor visual acuity in children with mild or moderate amblyopia was more significant than that in children with severe amblyopia(P<0.05). The difference of poor visual acuity was positively correlated with difference of perceptual eye position before and after treatment among children with amblyopia(r=0.371, P<0.05).
CONCLUSION: Visual perceptual learning can effectively improve the visual representation and binocular vision function of children with amblyopia, and it is suitable for the clinical treatment of children with amblyopia.
