RESUMEN
In order to evaluate the association between serum vitamin A levels and ocular lesions attributable to non-complicated malaria, 200 patients seen consecutively at the Malaria Outpatient Clinic of FUNASA, Manaus, Amazonas, Brazil were included in this study.

Vitamin A serum concentration was determined by HPLC, and deficiency was defined as serum values equal to or lower than 0.35 micromol/l. Serum vitamin A values between 0.36 and 0.70 micromol/l were considered as marginal levels. Hypovitaminosis A (
