Normative data taken on a sample of 10 eyes indicate that transscleral visual evoked response (TVER) stimulation of the cortical evoked response with a range of lights and at lower adaptation levels produces replicable, low-variance responses which may be of sufficient quality for the clinical evaluation of retinal and visual pathway condition. Response amplitudes were related to the radiant peak-power of white stimuli but were greater for red stimuli. Attenuation of the subjective brightness of the stimulus delivered through the inferior lid and sclera was about 0.4 log units compared to corneal delivery. Typical signal:noise ratios were 5:1.
对10只眼睛的样本进行的标准数据表明,经巩膜视觉诱发电位(TVER)在一系列光照条件下以及较低适应水平下对皮质诱发电位的刺激会产生可重复、低方差的反应,这些反应的质量可能足以用于视网膜和视觉通路状况的临床评估。反应幅度与白色刺激的辐射峰值功率有关,但红色刺激的反应幅度更大。与通过角膜传递相比,通过下眼睑和巩膜传递的刺激的主观亮度衰减约为0.4对数单位。典型的信噪比为5:1。
