DESCRIPTION OF A CASE SHOWING THE LATE OPHTHALMOSCOPIC APPEARANCES OF SUP- POSED EMBOLISM OF THE CENTRAL RETINAL ARTERY. On the 2d day of October, 1893, a sixty-four-year-old man, C. K., of South Bethlehem, Pennsylvania, applied to Dr. George C. Harlan’s clinic at Wills’ Eye Hospital. The patient, a worker in steel, stated that nine days previously, while knocking off clinkers from a grating, he noticed a sudden loss of vision, which lasted about two hours. Three days later the repeated itself, lasting this time but thirty minutes. During the following forty-eight hours his vision remained good, when, without any apparent cause, he experienced periodical attacks of dimness of vision and blindness. At the time of examination the eye was blind, the pupil was dilated, and the iris was immobile. A marked oedema, especially in and around the macula lutea, existed. A typical cherry-colored spot could be seen in the foveal region. Both the retinal arteries and veins were small, the arterial currents being thread-like and even invisible in places. The perivascular channels were thickened and opaque. No arterial pulse could be produced upon pressure. The left eye was unaffected, no fundus lesion could be detected, and vision could be brought to normal by the employment of a proper corrective lens. The patient was lost sight of until the month of May, 1894, when he voluntarily reappeared in order that he might obtain a glass for an increasing presbyopia. At this time, through the kindness of Dr. Harlan, the accom- panying sketch of the fundus-details, by Miss Margaretta Washington, of this city, was obtained. The eye was blind and the pupil was undilated and fixed. The media were clear, and the fundus-details, as here shown in the lithographic plate, SUPPOSED EMBOLISM OF THE CENTRAL RETINAL ARTERY. were those of optic-nerve atrophy, gross peri vasculitis, and retinal degenera- tion. Verbal descriptions of the late ophthalmoscopic appearance of this variety of disease are so rare in ophthalmic literature, and the visible changes in the present instance are so characteristic, that they have been deemed worthy of an accurate and faithful graphic representation. International Medical Magazine. AN ILLUSTRATED MONTHLY DEVOTED TO MEDICAL AND SURGICAL SCIENCE. edited, under the supervision of JOHN ASHHURST, JR., M.D., AND JAS. T. WHITTAKER, M.D., LL.D., BY HENRY W. CATTELL, A.M., M.D. THE development of medical science is proceeding at such a rapid rate that a medical journal is an absolute necessity to every practising physician. The International Medical Magazine supplies this need by giving, as it does, authorita- tive expression to the results of the experience and investiga- tions of the foremost physicians, surgeons, and lecturers of the leading medical schools of the United States and Canada, together with those of the great medical centres abroad, such as Eon don, Paris, Berlin, and Vienna. The contents of each number embrace Original Contributions and Clinical Lectures by leading practitioners, whose labors are exercising a directive, stimulating, and conservative influence on the healing art. In addition to these departments and with a view to securing ex- haustiveness, thoroughness, and reliability, specialists, tried in the school of experience and tested by their success in their specialty, have been placed in charge of separate departments embracing the following subjects: Medicine, Therapeutics, Neurology, Pediatrics, Surgery, Genito-Urinary Surgery, Orthopaedics, Obstetrics and Gynaecology, Ophthalmology and Otology, Laryngology and Rhinology, Dermatology, Hygiene and Bac- teriology, Pathology, and Climatology. To this must be added translations of what is best from the medical literature of Italy, Spain, and Portugal. The department of Forensic Medicine, dealing with medico-legal questions, and the legal duties and responsibilities arising out of, and incidental to, the relation of physician and patient, as ascertained and defined by courts of last resort, has proved an interesting and valuable feature of the Magazine, and called forth many expressions of apprecia- tion and approval from its readers. The department of Book Reviews furnishes a brief critical analysis of all the more important medical books and periodicals as soon as they are published. The Magazine becomes, therefore, the medium by which all that is settled as best, in every department of medical and surgical science throughout the medical world, is placed within the means of every practitioner.
