The dynamics of trace elements in eye tissues

: The dynamics of trace elements in various organs and eye tissues of NOD mouse and zinc deficiency rat were examined. Zinc content in eye tissues, especially the retina and choroid of NOD mouse with spontaneous diabetes mellitus and zinc deficiency rat were significantly decreased. Zinc uptake also was decreased in the retina and choroid, as compared with other organs. As a result, it was concluded that eye tissues, especially the retina and choroid were markedly reflected changes of the dynamics of trace elements.
