Case Study presented by Kevin Schreiber and Katie Stanton

History

The patient is a 61 year old right-handed white male who, while watching television, developed the sudden onset of blurred vision in his upper right visual field.This problem persisted even after alternately closing the right and left eyes.While continuing to watch television, he also noted difficulty in reading captions presented on the screen. He was able to read the captions only by sounding out each individual letter. Reading the word as a whole was impossible for him, but if he spelled the word aloud he could make sense of it. He could understand and could produce, speech without any difficulty. Later, while discussing his new problem with his wife, he discovered that he coud not perform calculation in his head- a task that, as an accountant, he could perform easily before. He denied weakness, numbnes, tingling, diplopia, dysarthria, dysphagia, dizziness, vertigo, or word-finding difficulty. He denied any previous difficulty with languahe and was previously an avid reader. When he arrived at the hospital, one day after the onset of his symptoms, the visual defict was improving but his reading problems persisted.
