To the Editor:
—Previously I have reported in The Journal seven cases that seemed to indicate hereditary tendency to cataract in some families.I operated lately on Mrs. T., aged 51, for cataract in the right eye that had been forming for four or five years. Recently the left eye became blind from the same cause.Just twenty-one years ago I had operated on this patient's mother, who was blind in both eyes from cataract, and who was then 54 years old. Her mother, the present patient's grandmother, was blind from double cataract when she died at 65. A full cousin of the present patient, a daughter of her mother's sister, was blind from cataract when she died of an acute disease at 50. So this is evidently another cataractous family.
