【摘要】：目的观察知觉学习提高大龄弱视患者视力和对比敏感度(contrast sensitivity,CS)的临床疗效。方法选择60例弱视患者进行知觉学习,训练前分别测量健眼和弱视眼的最佳矫正logMAR视力和7组空间频率对比敏感度,然后遮盖健眼对弱视眼进行知觉训练,每天训练1次,每次约30 min。以10 d为一个疗程,一个疗程结束后再对健眼和弱视眼分别进行矫正后logMAR视力检查和对比敏感度测试。结果训练前健眼logMAR视力0.020 0±0.105 0,训练后健眼logMAR视力0.004 4±0.099 6,差异有统计学意义(P=0.023 0);训练前弱视眼logMAR视力0.532 7±0.381 8,训练后弱视眼logMAR视力0.443 9±0.304 4,差异有统计学意义(P=0.000 0)。健眼训练前后7组空间频率对比敏感度均无统计学差异,弱视眼训练前后0.5、1、2所对应的空间频率对比敏感度差异无统计学意义,4、8、12、16所在空间频率对比敏感度差异有统计学意义(P0.05)。≤12岁的弱视患者,健眼和弱视眼7组空间频率对比敏感度训练前后差异均无统计学差异;12岁弱视患者,健眼训练前后7组空间频率对比敏感度仅12、16所在空间频率对比敏感度差异有统计学意义(P0.05),而弱视眼训练前后除空间频率2所在对比敏感度外,其他6组差异有统计学意义(P0.05)。结论知觉学习能显著改善弱视患者的各空间频率对比敏感度和视力,显著提高弱视眼的对比敏感度辨别能力,尤其是高空间频率对比敏感度,同时对健眼也有一定程度的改善。但该学习更适用于配合较好的大龄弱视患者。
[Abstract]:Objective to observe the clinical effect of perceptual learning on improving visual acuity and contrast sensitivity (CSA) in elderly patients with amblyopia. Methods 60 cases of amblyopia were selected for perceptual study. The best corrected logMAR vision and spatial frequency contrast sensitivity of 7 groups were measured before training. Each time is about 30 minutes. After a course of 10 days logMAR visual acuity test and contrast sensitivity test were performed on healthy eyes and amblyopic eyes respectively. Results the logMAR visual acuity was 0.020 卤0.105 0 before training and 0.004 4 卤0.099 6 after training, and the logMAR vision was 0.532 7 卤0.381 8 in amblyopia and 0.443 9 卤0.304 4 in amblyopia after training (P 0. 000 0). There was no significant difference in spatial frequency contrast sensitivity between 7 groups before and after eye training. Before and after amblyopia training, the spatial frequency contrast sensitivity of amblyopia eyes was not significantly different from that of 0. 5 and 1: 2 spatial frequency contrast sensitivity. There was significant difference in spatial frequency contrast sensitivity between two groups of amblyopia patients (P < 12 years old, P < 12 years old, P < 0.05), and there was no significant difference in spatial frequency contrast sensitivity before and after training. There was no significant difference in spatial frequency contrast sensitivity between healthy eyes and amblyopic eyes before and after training. The spatial frequency contrast sensitivity of 7 groups before and after normal eye training was significantly different (P 0.05), while that of amblyopia before and after training was significantly higher than that of the other 6 groups (P 0.05) except spatial frequency 2. Conclusion perceptual learning can significantly improve the contrast sensitivity and visual acuity of amblyopia patients, especially the high spatial frequency contrast sensitivity of amblyopia eyes, and improve the healthy eyes to some extent. But the study is more suitable for the older amblyopia patients.
