高斯化知觉学习系统的研发及其初步应用

The Design of Gaussian Perceptual Learning System and Its Preliminary Application

摘要: 目的：设计高斯化知觉学习训练方法，观察其对大龄弱视患者的治疗效果。方法：在液晶显示屏上显示空间频率可变的高斯化知觉学习光栅。应用于12例大龄弱视，3月后随访观察这些患者的弱视治疗效果。结果：大龄弱视治疗前后平均视力分别为0.42、0.67，统计学具有显著性的差异(P < 0.05)。结论：高斯化知觉学习训练是一个有效的大龄弱视治疗方法。

Abstract: Objective: To observe the treatment effect of Gaussian perceptual learning stimulation on elder amblyopic patients. Methods: Gaussian perceptual learning gratings with different spatial fre-quency were displayed on the computer’s monitor, the effect of 12 elder amblyopic patients was observed after three months. Results: Vision acuity was 0.42, 0.67 before and after treating re-spectively, there was significantly difference between them (P < 0.05). Conclusion: The Gaussian perceptual learning stimulation is a useful method to treat elder amblyopia patients.
