A patient with cystic fibrosis and cirrhosis developed a progressive neurological syndrome associated with ataxia, proximal weakness, and ophthalmoplegia. Profound deficiencies of vitamins A, D, and E were present. Visual acuity and results of retinal funduscopy were normal. The pattern reversal visual evoked potential was initially abnormal (P100 latency, 136 and 130 ms from left and right eyes, respectively) but became normal (less than 3 standard deviations from mean control P100 latency) over a two‐month period when vitamin E was administered. This case documents a potentially reversible visual evoked potential abnormality in a visually asymptomatic patient with vitamin E deficiency.
