[Clinical observations and calcium determinations in hypocalcemic cataract].

Among 38 cases of hypoparathyroidism, 32 patients were found to have hypocalcemic cataract. The morphology and mechanism of cataract formation were studied by clinical observation and biochemical calcium determinations, which indicated that the development of hypocalcemic cataract was related to the calcium level in blood but not to the duration of disease. The results suggest that early diagnosis and treatment of hypocalcemia may be useful in controlling the development of cataract. Calcium determinations showed that the blood calcium level was related to that in the aqueous humor. It is probable that the blood calcium content may reflect the calcium level in the aqueous humor, thus evaluating the tendency for cataract development.
