Tear calcium and magnesium levels of normal subjects and patients with hypocalcemia or hypercalcemia.

Abstract

Tear calcium and magnesium levels were measured in eight patients with hypercalcemia and two patients with hypocalcemia and compared to that of 72 subjects with normal serum calcium and magnesium levels. No correlation was found between tear and serum calcium and magnesium levels. Tear calcium level has no diagnostic importance.
