Eight children with corneal xerophthalmia (x2 or x3A) received standard high-protein diets and massive systemic vitamin A therapy. Retinoic acid, 0.1% in oil, was applied daily to one eye, and oil alone to the other. Topical retinoic acid proved safe and effective in speeding corneal healing, especially during the first critical days.
