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). ...
متن کاملFilter mount system for the miniature indirect binocular ophthalmoscope.

The recently introduced miniature indirect binocular ophthalmoscope of Schultz and Crock (Crock, Galbraith, and Parel, I969) offers a lightweight spectacle-frame instrument with ...
متن کاملSimplified 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...
متن کاملA new indirect ophthalmoscope prototype.
We have constructed a new indirect ophthalmoscope. This instrument has a T-shaped housing composed of an illuminating tube and a viewing tube. A fiberoptic light source provides illumination. The inverted aerial image of the fundus coincides with the plane of the viewing window of the housing. This unit can be easily connected to a television camera for television ophthalmoscopy or to an image ...
متن کاملUnderstanding and caring for an indirect ophthalmoscope
or indirect ophthalmoscope, is an optical instrument worn on the examiner’s head, and sometimes attached to spectacles, that is used to inspect the fundus or back of the eye. It produces an stereoscopic image with between 2x and 5x magnification. It is valuable for diagnosis and treatment of retinal tears, holes, and detachments. The pupils must be fully dilated for it to work well. In a dark r...
