目的　探讨图像视觉诱发电位 (PVEP)自律空间频率进行手、眼、脑联合训练法治疗儿童弱视。方法　用国产 DV- 10 0 PVEP分析系统检测弱视儿童的振幅与潜时 ,按其较好一档的振幅与潜时的空间频率作为第一张自律空间频率光盘刺激训练的信号 ,以后根据视力进步与 PVEP复查 ,再换相应的高空间频率来刺激训练 ,直到视力提高到 1.0。结果　 3～ 9岁弱视儿童 172例 (2 92只眼 ) ,随访 4～ 2 1月 ,视力提高≥ 0 .9者 78只眼 ,视力提高 2行以上者 16 6只眼 ,无效 4 8只眼 ,总有效率 83.5 3%。结论　 PVEP自律空间频率刺激疗法对儿童弱视有较好的疗效 Objective To investigate the relationship between the visual evoked potentials (PVEP) and the spatial frequency of self-regulation by hand, eye and brain in children with amblyopia. Methods The domestic DV-100 PVEP analysis system was used to detect the amplitude and latency of amblyopia children. According to their better amplitude and latent frequency, the first self-regulated space frequency CD stimulus training signal was used. According to the visual acuity improvement Review with PVEP, and then the corresponding high spatial frequency to stimulate training, until the eyesight increased to 1.0. Results 172 eyes (292 eyes) with amblyopia in 3 ~ 9 years old were followed up for 4 ~ 21 months. There were 78 eyes with ≥0.9 eyesight improvement, 16 eyes with vision improvement of 2 lines or more, and 48 eyes with no vision , The total effective rate of 83.5 3%. Conclusion PVEP autonomic spatial frequency stimulation therapy has a good effect on amblyopia in children
