ABSTRACT
@#AIM: To evaluate the effects of visual perceptual learning on visual representation and binocular vision function of children with amblyopia. <p>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. <p>RESULTS: The total clinical effective rate of children with mild amblyopia was higher than that of children with moderate or severe amblyopia(<i>P</i><0.05), and there was no significant difference in the total clinical effective rate between children with moderate amblyopia and children with severe amblyopia(<i>P</i>>0.05). The perception level of eye position after treatment of children with amblyopia was significantly lower than that before treatment(<i>P</i><0.05). The perception level of eye position after treatment in children with mild, moderate or severe amblyopia was significantly decreased(<i>P</i><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(<i>P</i><0.05). The poor visual acuity of children with amblyopia after treatment was significantly improved compared with that before treatment(<i>P</i><0.05). The poor visual acuity after treatment in children with mild, moderate or severe amblyopia was significantly improvement(<i>P</i><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(<i>P</i><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(<i>r</i>=0.371,<i> P</i><0.05). <p>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.
ABSTRACT
AIM: To observe the long - term effect of visual perceptual learning to correct anisometropic amblyopia in children.?METHODS: The clinical data of 200 children (200 eyes) with anisometropic amblyopia were retrospectively analyzed, which were divided into 2 groups according to therapeutic methods, and 82 children treated with traditional integrative therapy were distributed to the control group, while 118 children treated with visual perceptual learning were distributed to the observation group. After 1 year's treatment, the corrected vision, contrast sensitivity and stereo sharpness of patients were compared between groups.?RESULTS:After 1 year's treatment, the effective rate of the observation group was higher than the controls (90. 7％ vs 75. 6％, P<0. 05), and after 1 year's follow up, there was 92. 5％ patients maintained stabilization in the observation group, while that in the control group was 80. 6％, and the observation group was higher than the controls too, the difference between groups had statistical significance (P<0. 05). Before treatment, there was no significant difference in contrast sensitivity between groups (P>0. 05). After 6 and 12 months' treatment, the contrast sensitivity of both groups increased(P<0. 05), and the observation group was higher than the controls after 12 months' treatment, the difference between groups had statistical significance (P<0. 05). Before treatment, there was no significant difference in stereopsis acuity between groups ( P > 0. 05 ). After treatment, the stereopsis acuity of the observation group was better than the controls, and the difference between groups had statistical significance (P<0. 05).?CONCLUSION: The long-term curative effect of visual perception learning to correct children's refractive aberration is better than traditional comprehensive therapy.
ABSTRACT
Objective To investigate the compliance and its impact factors of amblyopic children treating with visual perceptual learning.Methods 116 amblyopic children treating with visual perceptual learning were investigated using self-made compliance questionnaire for amblyopic children treating with visual perceptual learning.Results The average compliance score of amblyopia in treatment of visual perceptual learning was(71.45±10.10) points,ranging from 36 to 92 points.The univariate linear regression analysis showed thatawareness of parents on the amblyopia training,communication with medical staff,parents supervise children training and eyesight improvement speed of children were the statistical significant impact factors.The further multivariate linear regression analysis showed that awareness of parents on the amblyopia training and parents supervise children training were also the statistically significant impact factors.Conclusions The compliance of amblyopic children treating with visual perceptual learning was satisfactory and its impact factors were associated with parents,the supervision and awareness of parents were the key impact factors for amblyopic children treating with visual perceptual learning.
