Mr. T., statesman, aged sixty, has had more or less pain on using his eyes for reading and writing, for a long time. About three weeks ago he was attacked, rather suddenly, with a mistiness of vision of both eyes. This haziness of sight has since remained about the same, and the pain in his eyes, has been more annoying than previously. He considers his general health fair for a man of his age. He smokes cigars excesssively and indulges freely in snuff. Each eye has vision f-g-, and both are emmetropic. He reads Jaeger No. 1 with his glasses. Ophthalmoscopic examination reveals the presence of numerous crystals of cholesterine in the vitreous humor. On causing him to move his eye about rapidly and then to suddenly fix it, beautiful showers of sparkling crystals are seen slowly falling, and flitting past each other in various directions, through the vitreous, and thus gradually settling down into the bottom of the vitreous chamber. The crystals having settled, the fundus can be seen to be normal. « Case 2.—April 4, 1876. Mr. M., aged fifty-two, a teacher in the public schools, says that his eyes have troubled him only within a few months. He has never used glasses for reading, and can still read Jaeger No. 1, with much apparent effort, at a dis¬ tance of thirteen inches. Vision = each eye, and no improve¬ ment with glasses. Reads more comfortably with No in¬ sufficiency of ocular muscles. Ophthalmoscopic examination shows sparkling synchysis of the left eye. Case 3.—June 29, 1876. Miss A. C. C., aged forty, when sev¬ enteen years of age fell from a horse, and “ injured her spine sympathetically.” She was a patient of Dr. J. Marion Sims, and was confined to a sofa most of the time for twelve years. Her eyes have been weak ever since the injury. They suffer from a sense of heat after being used, in reading or sewing, for a short time, and from aching, darting pains. There is an hereditary tendency to weak eyes in the family.
