Nearly One Hundred Years of the Ophthalmoscope
No instrument in general medicine has influenced and developed a specialty as the ophthalmoscope has done for ophthalmology. On the occasion of my lectures on the physiology of the sense organs, I made a discovery which may be of real value to ophthalmology; it was so simple, requiring no more knowledge than what I had learned of optics in high school, that it is laughable that other people and I could have been so obtuse as not to have recognized it before.
