In May, 1885, Geo. H., age thirty-seven, came to me from Indiana, with the following history: He had been very nearsighted all his life, but had never worn glasses. His eyes had never troubled him in any other way, until a few days before he came. He then noticed a few floating white spots before his left eye. This gradually increased, and the vision of this eye, by degrees, grew less and less until after four days the sight of the left eye was gone. There was no pain in either eye. Examination showed vision of the right eye was 4/200; with a — 13 Ds. glass, 15/200. With the left eye he could just distinguish light in the outer upper field of vision. With the ophthalmoscope only the lower fundus of the left eye could be made out, where the retinal vessels were seen up to the lower edge of the optic disk. The disk itself could not be made out, but above it a bulging, detached retina was prominent, with a hemorrhagic spot at its inner margin. In the upper outer fundus another separate bulging detachment of the retina could be plainly seen. The right eye was highly myopic, with a myopic arching around the disk, and the entire fundus was mottled with small choroidal pigmentation spots, clearly of long standing. The nature of his trouble was explained to him. He was kept quiet, and all forms of tobacco and stimulants were forbidden. He was placed on kali hyd. 3d, three times daily. In one week’s time a remarkable change for the better had taken place. The detachment was much reduced. The wavy retinal vessels were seen climbing over its edges. The optic disk was visible. In two days more he could count fingers with the left eye at two feet. The improvement continued. On June 24 vision of the left eye was 15/200; right eye, 15/100. He then went home for a few days; the kali hyd. being kept up. July 13 he returned, saying that the improvement had gone on by slow degrees, until, suddenly, the vision of the left eye was again lost, on July 12. He was then placed on 5‒grain doses of kali iod. 3d, three times daily, which was followed by very slow improvement, so that in three weeks he could again count fingers with the left eye at two feet, and the detachment, which had resumed its former dimensions, was somewhat reduced. I then went back to kali hyd. 3d, three times daily, which was again followed by improvement for some months after his return home. This, with some intercurrent medication, was kept up from time to time for a year, gradual improvement being reported until the sight of both eyes seemed about as it was in former years.
