一种新型的弱视诊断与治疗方法研究及系统实现

Study of New Amblyopia Diagnostic and Treatment Method and System Implementation

弱视是儿童发育过程中的常见病,传统的弱视治疗方法存在依从性差、易导致健眼视力问题、双眼视和立体视恢复效果差等弊端。该文提出了一种新型的个性化弱视诊疗系统,结合图形视觉诱发电位和双眼平衡视觉训练模式,通过采集脑电信号和同步触发信号,准确测量了图形视觉诱发电位(P_VEP)潜伏期和波形,实现了弱视的辅助诊断和治疗反馈,搜索得到了治疗训练图形的最佳空间频率,结合3D显示技术,提出了一种双眼平衡模式下的个性化弱视诊疗解决方案。

Amblyopia is the common disease in the children＇s growth. There are some disadvantages in traditional treatment to amblyopia, such as poor compliance, easily leading to the healthy eye eyesight problem, the poor recovery of binocular and stereoscopy vision, etc. This paper put forward a new individual amblyopia treatment system to solve these problems. It combined pattern reversal visual evoked potential （P_VEP） feedback and dichoptic training theory and then developed the EEG data acquisition and synchronized trigger circuit using and I/O data collecting card, realized the raw EEG signal real-time sampling, extracted VEP waveform from the raw EEG data by using digital filtering algorithm, average superposition algorithm and wavelet an Igorithm, finally, the latency and peak of P_VEP wave shape were accurately measured. This system also present an individual treatment solution based on dichoptic training model by searching and obtaining the best spatial frequency of the treatment training picture and combining with 3D display technology.
