Hypovitaminosis A caused by a malabsorption syndrome had led to nearly selective disturbance of rod function in a 30 years old female. No rod dark-adaptation could be recorded. The b-wave in the ERG was lacking and the EOG was flat. The cone function appeared to be unimpaired. This could be documented by normal cone-ERG, colour vision, visual acuity and central visual fields. Following treatment with vitamin A the subjective dark-adaptation, the b-wave in ERG and the EOG recovered. The results show that cones contribute barely to the oscillations of EOG.
吸收不良综合征导致的维生素A缺乏症，致使一名30岁女性几乎出现了视杆细胞功能的选择性障碍。无法记录到视杆细胞的暗适应情况。视网膜电图（ERG）中的b波缺失，眼电图（EOG）呈平坦状态。视锥细胞功能似乎未受损害。这可通过正常的视锥细胞ERG、色觉、视力和中心视野得以证实。补充维生素A治疗后，主观暗适应、ERG中的b波以及EOG均恢复正常。结果表明，视锥细胞对EOG的振荡几乎没有贡献。
