Page 10 - THE INFLUENCE OF SPECTACLES ON THE OPTICAL CONSTANTS AND VISUAL ACUTENESS OF THE EYE.
Page 34 - ... makes it probable, in his opinion, that the chorio-capillaris are essential in the production of osseous deposits, on account of its rich blood supply. Subsequent inquiry strengthened his views. Knapp further stated that the formation of bone in the eye is a consequence and a final stage of a plastic inflammation of the capillary layer of the choroid. He described the exudate as investing the inner surface of the choroid and continuing in the form of a transverse septum through the anterior part...
Page 34 - The diagnosis of ossification may be based upon the unyielding and hard condition of the posterior part of the globe, terminating about two lines behind the cornea, while the anterior region is soft, or at least impressible. Simultaneous occurrence of calcification and ossification is frequent. Calcification may be diagnosticated by atrophy or degeneration of the iris, in combination with a shrunken white or yellowish cataractous lens. As ossification does not involve the outer choroidal layers,...
Page 2 - ... power diminished still further, the double hearing continued for some time, and ultimately all musical sounds appeared to him so perverse that music in general, which he had been very fond of before, became a perfect horror to him. In none of these two cases mention is made which ear perceived rightly the natural tone, nor whether the pseudo-tone was higher or lower in pitch. The only well-analyzed case of the few cases of double hearing which are on record up to this day, is the observation...
Page 2 - The second patient had impairment of hearing from chronic aural catarrh for ten years. One evening, to shorten a fit of his habitual asthma, he anaesthetized himself by chloroform.
Page 57 - ... iris beneath it, is left behind, but the bulk of the tumor, and all the iris with which it was connected, are taken away. Since I wrote the foregoing, which was at the time of the patient's discharge, I have had repeated information with regard to. her health. The eye has completely recovered, there is no irritability of either eye, and no cystoid protrusion of the wound has developed. The lower part of the iris is somewhat drawn upward, encroaching upon the clearest portion of the pupil ; vision,...
Page 48 - ... outer portion of the iris, and became so much filled that it touched the posterior surface of the cornea, and crowded the iris and lens backward. The tumor was evidently still progressive. All the cysts of the iris which have been recorded up to this day (about 22 in number) were, when left untouched, destructive to the eye, and several of them even caused sympathetic inflammation of the other eye. I therefore was convinced that nothing but an early operation could save the eye of the patient,...
Page 1 - Roosa and .Moos, I have not recommended any more the use of the nasal douche, but applied injections of astringent remedies by the posterior nares syringe. They are disagreeable for a great many patients, producing very unpleasant fits of sneezing and coughing, but their action is efficient, and, as it seems, devoid of danger. If we inject only small quantities of fluid, which is mostly sufficient, there is commonly no unpleasant reaction.
Page 34 - ... septum, through the anterior part of the vitreous humor,. behind the ciliary body and the crystalline lens, "without, however, involving these structures. The diseases which lead to ossific productions are chronic inflammations of the interior coats of the eye, called internal ophthalmia by the earlier, irido-choroiditis by modern writers. It should be particularly mentioned that chronic plastic inflammation limited to the ciliary body and iris, irido-cyclitis, which is not uncommon, and leads...
