【摘要】：目的通过增加视觉诱发电位中不同空间频率的图像刺激信号，，找出患者的最敏感空间，进行针对训练，观察患者的治疗疗效及时间。方法将患者随机分为两组。实验组：进行PVEP检测，找出最敏感空间频率作为刺激源进行弱视训练，视力提高两行或以上时再次用VEP检测出新的敏感空间作为刺激源进行训练。对照组：从低频率到高频率依次进行弱视训练。结果实验组的有效率和治愈率均优于对照组，差异有统计学意义（P＜0.05）；3-6岁组，7-9岁组，10-12岁组的治愈率均有统计学差异（P＜0.05）；轻度弱视组、中度弱视组、重度弱视组之间的治愈率均有统计学差异（P＜0.05）。结论通过不同空间频率视觉诱发电位的检查，提供给弱视患者针对性训练，疗效显著，可用于弱视的临床治疗和推广，且年龄越小、弱视程度轻者疗效越好。
[Abstract]:Objective to find out the most sensitive space of the patients by increasing the image stimulation signals with different spatial frequencies in visual evoked potentials (VEP), and to observe the therapeutic effect and time of the patients. Methods the patients were randomly divided into two groups. The experimental group was tested with PVEP to find out the most sensitive spatial frequency for amblyopia training. When the visual acuity was improved by two or more lines, the new sensitive space was detected by VEP again as the stimulation source. In the control group, amblyopia training was carried out from low frequency to high frequency. Results the effective rate and cure rate of the experimental group were better than those of the control group (P < 0.05). The cure rate of 3-6 years old group was significantly different from that of 10-12 years old group (P < 0.05). The cure rate of mild amblyopia, moderate amblyopia and severe amblyopia was significantly different (P < 0.05). Conclusion through the examination of different spatial frequency visual evoked potential, it is effective to provide specific training for amblyopia patients. It can be used in clinical treatment and popularization of amblyopia. The younger the age, the better the effect of amblyopia.
