noun
Retina  n.  (Anat.) The delicate membrane by which the back part of the globe of the eye is lined, and in which the fibers of the optic nerve terminate. See Eye. Note: The fibers of the optic nerve and the retinal blood vessels spread out upon the front surface of the retina, while the sensory layer (called Jacob's membrane), containing the rods and cones, is on the back side, next the choroid coat.

"Retina" Quotes from Famous Books



... hast it in thy choice, which of the two), that gleams-in from the circumambient Eternity, and colours with its own hues our little islet of Time. The Understanding is indeed thy window, too clear thou canst not make it; but Fantasy is thy eye, with its colour-giving retina, healthy or diseased. Have not I myself known five-hundred living soldiers sabred into crows'-meat for a piece of glazed cotton, which they called their Flag; which, had you sold it at any market-cross, would not have brought above three groschen? ...

... masturbation was stopped, the eye trouble improved. Even in these cases, however, the troubles were but slight, the chief being, apparently, photopsia (a subjective sensation of light) with otherwise normal conditions of pupil, vision, color-sense, and retina. In some cases there was photophobia, and he has also found paralysis of accommodation and conjunctivitis. At a later date Salmo Cohn, in his comprehensive monograph on the relationship between ...

... circulatory process which, in its spasms of activity, gives rise to spots, produces in its regular course the singular "marbled" appearance, for the recording of which we are no longer at the mercy of the fugitive or delusive impressions of the human retina. And precisely this circulatory process it is which gives to our great luminary its permance as a sun, ...

... L. T. Troland of Harvard tells us, "are built up on the same principle as the ordinary 'half-tone' engravings; that is, they are made up of minute dottings or stripplings far too small to be detected by the eye. . . . The sensitiveness of the retina is so great that a visual sensation can be produced by relatively few Quanta of the right kind of light." Through a master's divine knowledge of light phenomena, he can instantly project into perceptible manifestation the ubiquitous light atoms. ...

Far off—even when occupied with the pressing claims of business—that portrait-face had often appeared upon the retina of his memory, and often also in the visions of dreamland.

The two pictures which I have already referred to, those of Erasmus and of Dr. Johnson, come up more distinctly before my mind's eye than almost any faces of the living. My mental retina has, I fear, lost much of its sensitiveness. Long and repeated exposure of an object of any kind, in a strong light, is ...

A great number of them settled along the edges of the eyelids, attracted by the sheen of the retina of the eye, into which they gazed with great interest. Others, more inquisitive, would explore the inside of your ears; while millions—actually millions—of pium, the tiny gnats—more impertinent than all the others taken together—dashed ...

Microscopic scrutiny reveals that it is made up in part of nerve cells containing a pigment similar to that present in the cells of the retina, thus clinching the argument for its ancient function as an eye. But the outstanding and specifically glandular cells are large secreting affairs, which too reach back to the tidewater days of our vertebrate ancestors, ...

Regarding the eye as analogous in its structure with the camera obscura of Baptista Porta, he discovered that the images of external objects were painted in an inverted position on the retina, by the union of the pencils of rays which issued from every point of the object. He ascribed an erect vision to an operation of the mind, by which it traces the rays back to the pupil, where they cross one another, and thus refers the lower parts ...

Anemia of the soft parts at the points of pressure results from prolonged sitting or lying in one position, and as a result pain compels a muscular action that shifts the damaging pressure—this is the pain of anemia; when the rays of the blazing sun shine directly upon the retina, pain immediately causes a protective muscular action—the lid is closed, the head turns away—this is light pain; when standing too close to a blazing fire the excessive heat causes a pain which results in the ...

Doubtless there was more—doubtless—I had seen pretty faces before, and knew that they were pretty, but they had passed from my retina, like the prints of beauties which I saw in the shop windows, without exciting a thought—even a conscious emotion of complacency.

In short, there is no insignificant line or mark that has not its memory or its indication of the strange phenomena of the upper world. True, the same picture is painted upon the retina of all classes of observers; and so Porson and a schoolboy and a peasant might receive the same physical impression from a set of black and white marks on the page of a Greek play; but to one they would be an incoherent conglomeration of unmeaning ...

Only an instant did he see it, photographed as by electricity upon the retina, when with a sharp stinging pang and whirring "whist" and thud a second arrow, better aimed, tore through the flesh and muscles just at the outer corner of his left eye, and glanced away down the hill. With one spring he gained the edge of the shelf, and shouted to the scouts to come on. Even ...

There is nothing in the realm of sound at all corresponding to the actual photographing of a visible object on the retina; our auditive apparatus, whatever its mysteries, gives no sign of being in any way of the nature of a phonograph. Moreover, one element of music is certainly due to the sense of locomotion, the rhythm; so that ...

It spreads the sensitive film on the artificial retina which looks upon us through the optician's lens for a few seconds, and fixes an image that will outlive its original.

The image of substantial and material loveliness once seen leaves an impression as distinct and perfect upon the retina of memory as upon that of the eyes.

By comparison of what is near with what is distant we learn that the tree, house, river, etc. which are ...
