Vitamin A deficiency (VAD) after bariatric surgery is recognised as a significant post-operative complication that can lead to visual impairment. We report two cases of night blindness and visual impairment caused by VAD after malabsorptive bariatric surgery. Both patients were treated with intramuscular vitamin A replacement and made near complete recovery in their vision. Ocular complications due to VAD should be diagnosed and treated promptly in patients after bariatric surgery because these complications are reversible.
术后维生素 A 缺乏症（VAD）被认为是一种严重的术后并发症，可导致视力损害。我们报告了两例因吸收不良性减重手术后 VAD 引起的夜盲和视力障碍。两名患者均接受了肌肉内维生素 A 替代治疗，视力几乎完全恢复。减重手术后的患者应及时诊断和治疗 VAD 引起的眼部并发症，因为这些并发症是可逆的。
