彩色图形视觉诱发电位已成功地作为一种敏感和客观的技术用于诊断先天性和获得性色觉缺陷。它也被用来表征颜色视觉通路的发育、成熟和老化。在这里,我们使用多焦点技术来确定全视野VEP的地形图成分。用VERIS™系统进行记录,该系统使用伪随机刺激序列提取地形图VEP。彩色图案刺激以起始-偏移时间序列呈现,颜色在MBDKL颜色空间中沿不同轴调制。另外还进行了实验,以验证每个观察者的S圆锥轴,以及我们的色度刺激在不同的视野位置上接近等照物。我们的数据显示,对于符合模式首发全场VEP波形特征的多个视网膜区域,可靠且稳健的彩色首发VEP反应。对于具有色度贡献的刺激,模式起始集产生可靠和一致的波形,而对于具有较大亮度贡献的刺激,模式反转刺激优于模式反转刺激。我们记录彩色多焦点模式发作的视觉诱发电位的方法有望在临床上应用于检测和监测与衰老和疾病相关的早期视网膜和视神经变化。
The chromatic pattern-onset VEP has been used successfully as a sensitive and objective technique to determine congenital and acquired color vision deficiency. It also has been applied to characterize development, maturation and aging of the chromatic visual pathways. Here we determine the topographic components of the full-field VEP using the multifocal technique. Recordings were made with the VERIS™ system that extracts topographic VEPs using a pseudorandom stimulus sequence. Chromatic pattern stimuli were presented in an onset-offset temporal sequence, with colors modulated along different axes in the MBDKL color space. Additional experiments were conducted to verify the S-cone axis for each observer and that our chromatic stimuli were close to isoluminant at different field locations. Our data show reliable and robust chromatic onset VEP responses for multiple retinal areas that conform to pattern-onset full-field VEP waveform characteristics. For stimuli with chromatic contributions, pattern-onsets produced reliable and consistent waveforms whereas for stimuli with large luminance contributions pattern-reversal stimuli were superior. Our method for recording chromatic multifocal pattern-onset VEPs holds promise for clinical application to detect and monitor early retinal and optic nerve changes related to aging and disease.
