PY - 1 T2 - Practice of Neural Science: A Case-Based Approach AB - For the past 6 weeks, a 52-year-old man has been having spells of transient monocular visual loss. Every few days, it seems as if a curtain descends over his right eye, with total loss of vision for several minutes. He has verified that only the right eye is affected by covering first one eye and then the other during the attacks. Within an hour of a typical episode, examination reveals a small yellowish refractile body at a bifurcation of an inferior retinal arteriole, obstructing distal flow. A soft, high-pitched, continuous, systolic murmur extending into diastole is present over the right anterior neck at the level of the thyroid cartilage. Physical and neurological examinations are otherwise normal. SN - PB - CY - New York, NY Y2 - 2024/03/28 UR - neurology.mhmedical.com/content.aspx?aid=1180669537 ER -
