Abbildungen des menschlichen Auges.
. Frankfurt am Mai, bei Varentrapp und Wenner, 1801, Folio, X, 110 pp., 16 Kupferstichtafeln, davon 8 Umrisstafeln, im feinen Halbledereinband der Zeit: St.a. Tit., die ersten und letzten Seiten etwas fleckig.. First Edition of this important Milestone of Ophthalmology! - Samuel Thomas Soemmerring (1755-1830) "is best remembered for his fine anatomical illustrations, of which those devoted to the human eye are a good example". - - Ludwig Choulant declared this book "Soemmerring's most perfect work" which with Zinn's monograph formed the basis for all modern research on the structure of the eye. - - "Soemmering explains in the preface to his book (1801) that the "Abbildungen des menschlichen Auges" originated from drawings which he himself had made from anatomical preparations or he had made the first sketches which then had been elaborated on. He declares that he did not spare time nor effort nor cost in order to produce these anatomical illustrations which should enable one to obtain a more correct and more precise picture of the natural and healthy structures of the eye. This should be of benefit when investigating the function of the eye as well as for the treatment of eye diseases. I first thought this to be more of a hobby but then I had the advantage of getting access to a number of human corpses and the cooperation of the excellent artist Chr. Koeck who could follow my ideas in a splendid way. My teaching obligations gave me a certain amount of free time and I was supported by many encouraging friends. Each plate shows the illustration in lines to which letters and numbers are attached explaining the various structures. Another illustration is then reproduced in various shades of white and black. - The first plate illustrates the healthy living eye. - "The eye of a man is in general round, thick and strong; the eye of a woman is more elongated, flat, gentle, thin and pleasant." The conjunctiva of a Negro is never as white, clear and transparent as that of a European; the iris is so dark brown that at a certain distance it can hardly be distinguished from the pupil. In the eye of an albino the iris seems to be discontinuous so that the red color of the fundus can be seen not only through the pupil but also through these tissue defects. The eyes of albinos were in constant movement and even the iris made quicker than normal motions. During sleep the lids are closed in such a fashion that the upper lid is farther downward on the temporal side than nasally; the eye is somewhat rolled upward and the lower lid usually keeps its skin fold; the lashes cross each other. - The second plate illustrates the lids, the muscles, the nerves (as they have never been shown previously), the arteries and veins and the lacrimal apparatus. - The third and fourth plates show the extraocular muscles with their nerves and blood vessels. - The fifth plate shows the details of the interior of the eye. "I probably would never have noticed the central hole in the retina had I not had the chance to examine the eyes of a young man who had recently drowned." - "In the center of the retina is a very conspicuous round hole with a golden yellow margin around which blood vessels form a beautiful wreath." (Compare § 723, Buzzi, 1782.) - "I shall skip the differences between a hyperopic and a myopic eye". - The four main branches of the central vein are correctly illustrated, the corresponding arteries are still somewhat incompletely sketched. - The seventh plate shows the orbit and the eighth the profile of the eye seen from the left; it also shows a vertical cross section through the closed lids, the eyeball and the orbit. It has been reproduced often in various books on ophthalmology." F.C.Blodi/ Hirschberg 464 - - Garrison & Morton No.1489; Hirschberg 464; Becker Collection Nr.348
