To describe vitamin A deficiency using multimodal functional visual assessments and imaging.
METHODS/CASE: A 50-year-old female with past medical history significant for Roux-en-Y gastric bypass surgery complained of nyctalopia and "yellowing" of vision.
Vitamin A levels were noted to be < 0.06 mg/L (normal 0.3-0.12 mg/L). Fundus examination was notable for peripheral yellow punctate lesions, superior arcuate defects on HVF 30-2 testing, an indistinct ellipsoid zone on SD-OCT, and absent rod responses and severely reduced amplitudes for the cone photoreceptors on full-field ERG. These findings resolved with initiation of parenteral vitamin A supplementation.
This report documents an example of vitamin A deficiency in the developed world. We aim to provide a comprehensive description of clinical examination and multimodal imaging findings before and after vitamin supplementation for vitamin A deficiency.
使用多模态功能视觉评估和成像来描述维生素 A 缺乏症。
方法/案例:一名 50 岁女性,既往病史为 Roux-en-Y 胃旁路手术,主诉为夜盲症和“视力变黄”。
维生素 A 水平<0.06mg/L(正常值 0.3-0.12mg/L)。眼底检查可见周边黄色点状病变,HVF 30-2 测试显示上方弓形缺损,SD-OCT 显示椭圆体带不清晰,全视野 ERG 显示杆状细胞反应缺失,锥状细胞振幅严重降低。这些发现随着静脉内补充维生素 A 而得到改善。
本报告记录了一例发达国家的维生素 A 缺乏症。我们旨在为维生素 A 缺乏症患者提供全面描述,包括补充维生素 A 前后的临床检查和多模态成像结果。
