阿拉斯加雪橇犬的视网膜电图（ERG）只含有视杆成分。在暗适应过程中，通常用红光刺激引起的明视b波不存在，并且使用闪烁刺激时，仅存在闪烁融合反应曲线的第一或杆分支。在高刺激强度水平下，不存在hemeralopes的闪烁反应。使用蓝光刺激和低强度白色光从受影响的狗记录正常的ERG。在成年的Hemeralope中，视网膜不包含锥体。
The electroretinogram (ERG) of hemeralopic Alaskan malamute dogs contains only rod components. There is absence of the photopic b-wave which is normally elicited with red light stimuli during dark adaptation and, using flicker stimulation, only the first or rod branch of the flicker fusion response curve is present. At high stimulus intensity levels, the flicker response of hemeralopes is absent. A normal ERG is recorded from affected dogs using blue light stimuli and low intensity white light. In the adult hemeralope, the retina contains no cones.
