Hypovitaminosis A is a well-recognized condition in many developing countries. However, in the developed world the diagnosis is frequently missed or delayed because of its rarity. A 67-year-old man from metropolitan Adelaide presented to us with gradual but severe bilateral visual loss. He had marked punctate epithelial keratopathy in both eyes. Hypovitaminosis was suspected because of his bizarre dietary habit, and this was confirmed by a combination of impression cytology of the ocular surface and biochemical testing of his venous blood. His vision responded dramatically to vitamin A supplementation. Hypovitaminosis A should be suspected in severe cases of 'dry-eye', especially in those patients with unusual dietary habit or malabsorption.
