There is nothing new in the fact that disturbances of the parathyroids can cause, among other things, opacities in the crystalline lens; this has been established since 1888, when Landsberg reported the first case. Even prior to that cases of cataract associated with tetany or with muscular cramps that were probably tetany were reported. The parathyroids are small and are closely related to the thyroid, so that in operating on the thyroid it is easy to damage them by removal, by interference with their blood supply or by involving them in cicatricial tissue. The outstanding evidence of interference is the development of tetany. Their influence on calcium metabolism shows itself in a reduction of the calcium content of the blood and an increase of phosphorus. About forty-five cases of parathyroid cataract have been recorded, which probably represents a small proportion of the number that have been observed. The two
