THE MEASUREMENT OF AUDITORY ACUITY
Walter A. Wells · JAMA · 1913
taken with acute ethnioiditis following a cold which he con- tracted in St. Louis.He came ,to Omaha.I found complete blindness in the right eye and that he could count the fingers with the left eye at not farther than 2 feet.The skia- gram showed both sphenoids filled with pus.On opening both sides the condition at once cleared up.Du. W. B. PARKER, Detroit: Dr. Shambaugh's cases illus- trate well the point I wished to make.Two patients were without eye Symptoms and one undoubtedly showed eye symptoms of sinus origin. 1 think these conditions are possible, but rare.I did not include in the paper inflammatory conditions of the conjunctiva or cellular tissue of the orbit, nor did 1 include reflex headaches, or cases of corneal ulcérations which depend on affections of the lacrimal apparatus.Cases' of this kind arc more common and well understood.Sly experience agrees with that of Dr. Dwight.In large student bodies we do meet cases of rcllcx headaches due to eye or nose affections.In these cases congestion of the mucous membrane of the nose, of the sinus and of the eth- moid colls may be found.A low-grade retinitis or a "fluffy chorioid" may also be found.You may refract and re-refract in these cases, but you will not cure them.If you relieve the nose and sinus condition, the patient will at once feel better.The trouble is not, it seems to me, due to the use of the brain, but rather to a relaxed condition of the mucous membrane incident to sedentary life.Get these persons out in the fresh air, with exercise and good food, and their symp- toms will disappear.
