Abstract
On one hundred cases of empyema, classifying them into three groups; slight medium and serious, I have investigated their states of eyes of pre and after-operation. The result of which shows the following; one who has an ophthalmic trouble among these, slight-11.1%, medium-12.8%, serious-28.6%, and the former two have lessened after operation, but the serious have increased. The sight had a tendency of betterment a little after operation, but it was not remarkable. One who had a difference of right and left in a grade of protrusion of the eyeballs was recognized by percentage of 50 in the slight, 51.9 in the medium and 83.3 in the serious. The differences are within 1 mm. in the slight, 3 mm. in the medium and 6 mm. in the serious, and they increase gradually. Every case has progressed favorably after operation. The central scotom was proved by 6% in the slight, 14.5% in the medium and zero in the serious. This has disappeared or dimidished after operation. 3% of them have become wider and 4% of them have become narrower in a field of vision. On the fundus changes, hyperemy of the disk and opacity of retina around the disk were observed in a small number of cases, but it is not positive about the influence upon a disease in the nose.
