| ［摘要］ 目的 了解近视性弱视患者在视知觉学习治疗中近视屈光动态变化规律。方法 选择2006～2009年在广西视光中心弱视门诊行视知觉学习治疗的近视性弱视患者54例（98只眼），前瞻性收集患者治疗前后的近视屈光度，并对治疗前后屈光动态按患者弱视程度、近视程度和疗效等特征进行分层分析。结果 (1)近视性弱视视知觉治疗后的球镜和等效球镜高于治疗前（P<0.01）；球镜、等效球镜的年均变化为（0.52±0.79）D/年和（0.54±0.81）D/年；等效球镜年均增长在1.00 D以内者占76.53%，年均增长超过1.00 D者占23.47%。(2)轻、中、重度弱视的球镜和等效球镜动态变化差异均有统计学意义（P<0.01），但柱镜动态变化差异无统计学意义。(3)轻、中、重度近视弱视眼的球镜、柱镜和等效球镜动态变化差异均无统计学意义（P>0.05）。(4)不同疗效的弱视眼屈光度动态变化差异无统计学意义（P>0.05），但球镜和等效球镜呈现出从无效到治愈逐渐降低趋势。结论 近视性弱视视知觉治疗后近视屈光度增长，且主要来自于球镜的增长，弱视重度弱视屈光动态变化超过轻、中度弱视，不同近视程度和疗效弱视眼的“近视化”未见明显差异。 |

| ［Abstract］ Objective To explore the myopic diopter dynamics of the myopic amblyopia during the treatment of perceptual learning.Methods Refractive diopter of the 54 children with myopic amblyopia (98 eyes) were prospectively collected，which was selected from the amblyopia clinic between 2006 and 2009, and the myopic diopter dynamics before and after perceptual learning were analyzed according to the degree of amblyopia, myopia and the curative effect.Results (1) The spherical and spherical equivalent (SE) of children with myopia amblyopia after visual perception treatment was higher than that before treatment (P<0.01); the annual average change of spherical and SE were (0.52±0.79)D/year and (0.54± 0.81)D/year; the annual average growth of SE less than 1.00 D accounted for 76.53%, in contrast, average annual growth more than 1.00 D accounted for 23.47%. (2) The dynamic changes of spherical or SE of light, moderate and severe amblyopia have the significant difference (P<0.01), but the dynamic changes of cylinder was no significant difference between them. (3)The dynamic changes of spherical, cylinder and SE between the mild, moderate and severe myopia amblyopes was no significant difference (P>0.05). (4) the spherical and SE showed decreased trend from ineffective to cure, however, the dynamic changes of refractive diopter between different curative effects of amblyopia showed no significant difference (P>0.05).Conclusion The myopia diopter of the myopic amblyopia increased after the visual perception treatment, which may be contributed to the growth of spherical diopter, refractive change of severe amblyopia is higher than those of mild or moderate degree of amblyopia, the myopic degree and efficacy have no effect on myopization. |
