Calcium: I. Ocular and systemic metabolism

The research cited above has shown that calcium and related minerals play a significant role in the maintenance of ocular and systemic health. While it is difficult to obtain a complete picture of calcium metabolism in any given patient, the tests previously discussed (most of which can be performed by or at the direction of an optometrist) do serve to differentiate patients with normal versus aberrant calcium dynamics. Since calcium is important to the proper function of the visual system, the optometrist should be alert to signs and symptoms which can indicate calcium metabolic or nutriture imbalances, and test, counsel or refer suspect patients appropriately.
