Global ERG recordings are only modified in conditions with diffuse or extensive retinal involvement. The use, over the last 6 months, of a new functional testing device: VERIS (visual evoked response imaging system) allows accurate detection and quantification of localized retinal function defects. Our preliminary experience shows that a careful preparation of subjects, standardized testing protocols and a good understanding of the device technology, especially software parameters are mandatory. We report our results on a series of 28 normal volunteers, grouped by age and describe the various graphic presentation of data collected. This technology should allow accurate detection and quantification of retinal functional defects in patients with age related macular degeneration as well as evaluation of visual function in retinitis pigmentosa patients before and after photoreceptor transplantation.
全视网膜电图（ERG）记录仅在弥漫性或广泛性视网膜受累的情况下发生改变。在过去6个月中使用了一种新的功能测试设备：VERIS（视觉诱发电位成像系统），它能够准确检测和量化局部视网膜功能缺陷。我们的初步经验表明，对受试者进行仔细准备、采用标准化测试方案以及充分了解设备技术，尤其是软件参数是必不可少的。我们报告了对28名正常志愿者按年龄分组的一系列研究结果，并描述了所收集数据的各种图形呈现方式。这项技术应能准确检测和量化年龄相关性黄斑变性患者的视网膜功能缺陷，以及评估视网膜色素变性患者在光感受器移植前后的视觉功能。
