Elemental concentrations in ocular tissues of various species.

An investigation was undertaken to expand the data base for elemental concentrations within eye tissues of different species. This report provides data on the distribution of calcium, copper, iron and zinc in human, dog, bovine, bird, amphibian and fish ocular tissues. The variation between different eyes of the same individual and different individuals was calculated for each metal. Elemental concentrations between the left and right eyes of an individual were usually closer in value than between two eyes of different individuals.
