The ocular function of 14 non‐alcoholic, highly icteric patients with recent occlusion of the common bile duct and 3 patients with viral hepatitis with a cholestatic pattern was studied. By means of a colour vision test panel including the Farnsworth‐Munsell 100‐hue test, 12 patients were initially classified as colour defective with a pattern of acquired colour vision deficiency (ACVD), predominantly of a tritan type. Visual acuity, visual field, slit lamp microscopy, intraocular pressure, ophthalmoscopy and tear secretion tests were normal, and all patients had normal levels of serum vitamin A. Retesting of 4 initially colour defective patients after disappearance of the obstructive jaundice showed a complete normalisation of the ACVD's. It is concluded, that the colour perception in patients with obstructive jaundice is related to the serum bilirubin level, and not to a deficiency of vitamin A.
