SUBSEQUENT to a preliminary report made on nutritional dystrophy of the corneal epithelium,1 facilities for examination of the blood and urine for various vitamins, viz., vitamin A and carotene in the blood and thiamine and riboflavin in the urine, were made available through the courtesy of the Institute of Nutrition, Department of Health, Republic of the Philippines.
While at the time of the preliminary report the impression was entertained that such a type of corneal dystrophy was of nutritional origin, and while therapeutic tests seem to bear out the assumption that it was due to hypovitaminosis in the B complex group, nevertheless, the absence of supportive biochemical examinations precluded definite conclusions as to the etiology.
The cases covered by this report were seen in Lucena, Philippines, within the period from September, 1950, to August, 1952, inclusive, and in a number of them examinations have been made for blood level
