Cataracts and riboflavin deficiency

H W Skalka, J T Prchal

    The American Journal of Clinical Nutrition
    |May 1, 1981
    PubMed
    Summary

    This study found no link between riboflavin deficiency and early cataract formation. While older cataract patients showed more deficiency, it did not appear to cause cataracts in the general population.

    Area of Science:

    • Ophthalmology
    • Nutritional Science
    • Biochemistry

    Background:

    • Reduced glutathione, vital for lens health and diminished in cataracts, requires flavin adenine dinucleotide (FAD) as a coenzyme for glutathione reductase.
    • Riboflavin is a precursor to FAD, leading to the hypothesis that riboflavin deficiency might contribute to cataract development.

    Purpose of the Study:

    • To investigate the association between riboflavin nutritional status and cataract formation.
    • To evaluate riboflavin levels in various patient groups, including those with and without cataracts, across different age groups.

    Main Methods:

    • Assessed riboflavin nutritional status in healthy young adults, presenile and senile cataract patients, and young and older individuals with clear lenses.
    • Compared riboflavin levels across these distinct demographic and clinical groups.

    Main Results:

    • No evidence of an association between riboflavin deficiency and early cataract formation (idiopathic or secondary) was found.
    • Older cataract patients exhibited a higher prevalence of riboflavin deficiency compared to younger individuals.
    • Older individuals with clear lenses did not show evidence of riboflavin deficiency.

    Conclusions:

    • Riboflavin deficiency does not appear to be a direct cause of early cataract formation.
    • While older cataract patients may have lower riboflavin status, this deficiency is not considered cataractogenic in the general population.
    • Age may influence riboflavin status, independent of cataract presence.
