Ocular symptoms as the initial signs of zinc deficiency.

A 2-year-old boy with a history of food allergy presented with severe edema and erythema, excoriations and honey-colored crusting on both lower eyelids, and erythematous rash on his perioral region. An evaluation for micronutrient deficiencies revealed low plasma zinc level. The patient was started on a regimen of zinc supplementation, and at 4 weeks' follow-up there was nearly complete resolution of the lesions.
