| 目的 通过增加不同空间频率视觉诱发电位中图像刺激信号,找出患者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岁组的有效率均有统计学差异(P<0.05);轻度弱视组、中度弱视组、重度弱视组,每两组之间的有效率均有统计学差异(P<0.05)。结论 通过不同空间频率视觉诱发电位的检查对弱视患者进行针对性训练的疗效显著,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。 |

| Objective To identify the most sensitive visual space of the patients by increasing different spatial frequency image stimulus signal in the visual evoked potential and to observe the therapeutic effect and timing of the patients. Methods Patients were randomly divided into two groups. In experimental group, patients were detected by PVEP to find out the most sensitive visual space to spatial frequency as a stimulus for amblyopia training and then detected by VEP when patients,vision was improved two lines or more. In control group, the amblyopia training of patients was carried out from low frequency to high frequency in turn.Results The efficiency and the cure rate of the experimental group was better than that of control group, and there was significant difference between the experimental group and the control group (P<0.05). There was significant difference in the cure rate of 3-6 years old group, 7-9 years old group and 10-12 years old group(P<0.05).Conclusion Specific training to amblyopia patients can be used in the clinical treatment and gain obvious curative effect. |
