Some years ago, the speaker demonstrated that vertebrate retinal photoreceptors are fiber optics
elements and waveguides, and he succeeded in defining many of their properties. For a summary of
much of this research, please see the reference to Enoch and Tobey listed below (Reference 4).
Included are studies of photo-receptor alignments and maintenance of receptor alignments across the
retina in normal and abnormal human eyes. With very rare exceptions, rod and cone photoreceptors
across the retina align remarkably and precisely with the center-of-the-exit-pupil-of-the-optics-ofthe-
eye throughout the lifetime of the individual! And within a modest period of time (a day or a bit
more), it proved possible to alter that photoreceptor alignment by physically displacing the pupillary
aperture; and with recentration of the eye pupil, these alignments recovered their original state.
Here, the author asks, "Might advantage be gained by developing alignment sensitive, photoactivated,
waveguide/fiber optic units? That is, might comparable mechanisms be adapted in a
useful manner to non-biological fiber-optics applications? Since such characteristic responses have
been clearly of great value for biological species; might similar designs serve other important
roles?"
