A Rare Cause of Bilateral Corneal Ulcers: Vitamin A Deficiency in the Setting of Chronic Alcoholism.

Vitamin A deficiency is rarely encountered in the western world. When encountered, vitamin A deficiency is seen as a component of the malabsorption spectrum of disease. Given the infrequency of nutritional deficits in the developed world, vitamin A-associated ophthalmologic disease is rarely encountered. We report a case of a 56-year-old male with severe vitamin A deficiency in the setting of alcoholic liver cirrhosis. This case emphasizes two important points. First, it considers vitamin A deficiency as a cause of corneal ulceration in patients with chronic alcoholism. Second, it raises awareness of hepatotoxicity that can result after the supplementation of vitamin A in patients with chronic alcoholism. Although an uncommon diagnosis, it should be considered when other causes, such as infectious and autoimmune conditions, are ruled out.
