Origin of entoptic¹

Example Sentences

It seems safer to term them entencephalic, on the analogy of entoptic, since they seem to be due to something in brain-structure, much as entoptic percepts are due to something in the structure of the eye.

From Project Gutenberg

From these entencephalic photisms we seem to proceed by an easy transition to the most inward form of unmistakable entoptic vision—which is therefore the most inward form of all external vision—the flash of light consequent on electrisation of the optic nerve.

From Project Gutenberg

Midway, again, between entoptic and ordinary external vision we may place after-images; which, although themselves perceptible with shut eyes, presuppose a previous retinal stimulation from without;—forming, in fact, the entoptic sequel� of ordinary external vision.

From Project Gutenberg

In their simplest spontaneous form they are the cerebral sequel� of external vision, just as after-images are its entoptic sequel�.

From Project Gutenberg

The chapters on Ophthalmometry, Ophthalmoscopy, Accommodation, Astigmatism, Aberration and Entoptic Phenomena, etc.—in fact, the entire book contains so much that is new, practical and necessary that no refractionist can afford to be without it.
