A PRIMARY INTRADURAL TUMOR OF THE OPTIC NERVE

Abstract

History. —L. H., a negro girl, aged 15 years, came to the clinic of the University of Tennessee in November, 1915, complaining that the right eye had protruded for five years and was blind. There was no history of trauma, and the date of the beginning of the protrusion of the eye, as well as of the beginning of the failure of vision, was not definitely ascertained. Examination. — The right eye was prominent and turned inward and upward (Fig. 1). Motion was preserved except outward. The proptosis measured 25 mm. with the exophthalmometer, as compared to 15 mm. in the left eye. The pupil was dilated and fixed and the eye was blind, but the external appearances were normal in every way. There were postneuritic atrophy of the optic nerve and some tortuosity of the veins; otherwise the eyeground was normal.
