BURKE'S REFLECTING OPHTHALMOSCOPE.

The Ophthalmoscope

Miniature binocular indirect ophthalmoscope.

The optical principles of indirect ophthalmoscopy were mastered by Gullstrand (I 9 I I) although his ophthalmoscope did not achieve wide popularity because of its complexity and limited field of view. Schepens (I947) demonstrated his binocular indirect ophthalmoscope 2I years ago in the United States of America. The instrument described here is a further stage in simplification (Figs I and 2). ...

Simplified Indirect Ophthalmoscope.

INDIRECT ophthalmoscopy is one of the most important methods of fundus examination, especially in cases of detachment of the retina. The advantages of this method over direct ophthalmoscopy include a larger field of view, a more brilliant image, and a greater depth of focus. It is especially valuable for the examination of the highly myopic eye. The stereoscopic view obtained with the binocular...

In 1703, Jean Méry reported that the luminosity of the cat's eye could be seen when the animal was held under water, and Mariotte observed that a dog's eye was luminous but erroneously thought this was because its choroid was white.

The second, in addition to his clinic...
