Binocular direct ophthalmoscope.

Archives of Ophthalmology, 1969
In the study of small areas of the fundus as the disc and macula, depth relationships may be of considerable importance. A binocular direct ophthalmoscope has been designed to accomplish such observation with greater simplicity than other techniques. The instrument produces a magnification of 15 times, an excellent stereoscopic effect, and is hand held.

Directional light scanning laser ophthalmoscope

Journal of the Optical Society of America A, 2005
The cone photoreceptor mosaic of the living human eye has in a limited number of cases been imaged without the use of wavefront-correction techniques. To accomplish this, the directionality of the photoreceptors, as manifested by their waveguiding properties, may be used to advantage.
