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.
