摘　　要：该文运用自适应光学矫正系统对人眼做实时高低阶像差矫正,并在此条件下结合知觉学习分别对4例屈光参差性和4例斜视性青少年弱视患者进行视觉训练。结果显示,基于同样的方法,训练后4名屈光参差性弱视患者的对比灵敏度函数(CSF)得到统计意义上的显著提高,而4例斜视性患者的对比度敏感函数则无明显变化。为验证对比度敏感函数结果的可靠性,同时对所有被试进行中心视力测试,测试结果与CSF结果一致。最后对实验结果进行分析,说明结合高低阶像差矫正下对弱视人眼进行视知觉训练的方法对屈光参差性弱视有治疗功效,但不适用于斜视性弱视的治疗。Visual perceptual learning with aberration corrected by adaptive optics visual stimulator system (AOVS) is applied to human eyes. Four subjects with anisometropia and four subjects with strabismus are trained by this way. Statistical results show that based on the same method, the contrast sensitivity function (CSF) of four subjects with anisometropia are improved significantly than that of four subjects with strabismus. The comparison of visual acuity (VA) between two groups is performed before and after the training. Experiment results prove that the proposed method is effective for subjects with anisometropia but not effective for subjects with strabismus.
