The diagnosis of Bitotís spots will be confirmed by an eye specialist or opthalmologist. Vitamin A status is measured by tests for retinol, with blood-serum retinol concentrations of 30-60 mg/dl considered in the normal range. Levels that fall below this range indicate Vitamin A deficiency.
This condition results from a buildup of keratinized epithelial debris and secretions that can be found in the conjunctiva. These spots are a sign of Vitamin A deficiency and are usually accompanied by night blindness.
Treating Bitotís spots first and foremost involves improving the individualís diet. Regular and adequate intake of foods rich in Vitamin A can reduce symptoms of Bitotís spots such as night blindness. Other medical conditions such as respiratory tract infections, diarrhea and measles that may be present should also be treated immediately.
Usually, topical antibiotics are administered to prevent secondary bacterial infection. Vitamin A deficiency and the early stages of xerophthalmia can be reversed by administration of a massive does (200,000 IU or 110 mg of retinol palmitate) orally on two successive days. Children with corneal ulcers should receive vitamin A whether or not a deficiency is suspected.
