Electro-oculogram in vitamin A deficiency associated with cystic fibrosis. Short communication

Ophthalmic Paediatr Genet. 1992 Sep;13(3):187-9. doi: 10.3109/13816819209046488.

Abstract

Electro-oculograms (EOGs) were recorded in a patient with cystic fibrosis and vitamin A deficiency before and during vitamin A supplementation (25,000 IU/day). Before vitamin A supplementation the EOG Arden light/dark ratio was 1.27. After seven months of vitamin A supplementation the Arden ratio increased to 3.0. These results reveal that vitamin A deficiency can cause an abnormal EOG.
