History.—I. O. D., a girl, aged 12, was referred to the Memorial Hospital, Richmond, on Aug. 31, 1932, by Dr. S. P. Hileman, of Millboro, Va., because of frontal headache, progressive loss of vision, and drowsiness. Headache was first noticed six months previously, being occasional and not accompanied by nausea or vomiting ; school work was continued. The school nurse found subnormal vision and advised refraction.
Glasses were fitted in June by Dr. Frank Wysor, of Clifton Forge, Va., who furnished the following notes : "My records show that I. O. D. was sent to me for refraction on May 31, 1932, and that her vision at that time was 20/40.
