Vitamin A intoxication by overdosage and vitamin A deficiency due to fat malabsorption represent clinical situations in which techniques for the assessment of tissue vitamin A are highly desirable. In the present study a method has been elaborated for the quantitative determination of dark adaptation. Since current chemical methods may be open to criticism, a functional test related to the availability of vitamin A in the tissues appeared to represent an approach worth exploring.
