Luminous Ophthalmoscopes.
Morton Inskeep Luminous Ophthalmoscope Patent. (Fig. 5.)
Fig. 5.
The arrangement of condensing lenses and lamps gives a better illumination than heretofore in luminous ophthalmoscopes. The form of mirror and aperture permit a good view of the fundus when seen through a smaller pupil than has been considered possible heretofore, and hence in those cases when a cyclopaegic is not indicated the instrument is an especially valuable ophthalmoscope.
The Inskeep Ominous Retinoscope, (Fig. 6,)
Fig. 6.
This is a compact instrument, the light being located in the handles as in the luminous ophthalmoscope. The mirror and aperture are sufficiently elongated in their greatest diameter to have the effect of a round mirror and aperture when in use. There are two condensing lenses, that next the mirror being fixed, and the other adjustable in .the tube. By means of this adjustable lens, one is able to produce a light as from a concave or plane mirror at will.
