Book excerpt: Excerpt from American Journal of Ophthalmology, Vol. 14: Being the Ophthalmic Year Book, Containing a Digest of the Literature of Ophthalmology, for the Year 1917 and Parts of 1918 This section reviews the literature of 1917, on ophthalmic diagnosis in general. Papers referring to the diagnosis of any particular disease will be found mentioned under the heading of that disease or the class to which it belongs. Ophthalmoscopy. - Lucanus to examine the anterior media illuminates the eye with the ophthalmoscope from a distance of one-half meter, and views it through a convex 6 D. lens held nearly its focal distance from the cornea. This magnifies the cornea about two diameters and shows minute foreign bodies, epithelial lesions, and minute opacities that are invisible by ordinary oblique illumination. Feilchenfeld, to secure a dark-room in a large light ward, has used an umbrella with a black curtain attached to its margin much as suggested by Lundsgaard (O.Y. B., v. 11, p. 18). Beneath this the patient and surgeon can escape the general illumination around them. Blanco adopts the view that the unfavorable results on vision following the use of arsenical preparations, especially salvarsan and neosalvarsan, are due to the exaggeration of previously existing ocular diseases. He therefore urges that prior to their administration a careful ophthalmoscopic examination should be made; and believes that when the eyes are strictly normal the therapeutic use of such drugs is not dangerous. Best, in 328 cases of serious war injuries to the head, found choking of the disc in 40 per cent. But in the first year of the war they amounted to 45 per cent., and in the second year to only 25 per cent., the improvement being ascribed to early and frequent intervention. The choking was more marked on the side of the injury in 61 out of 70 cases. In one case the swelling appeared as late as the fifty-second day. In a war atlas of ophthalmoscopy v. Szily has published plates of various injuries in the ocular fundus. The post-mortem segmentation of the blood column in the retinal veins due to coagulation has been described by Kahn, who records his observation in three cases. The interruption of the venous blood column gave the appearance indicated in the accompanying illustration. Such interruptions were found in the larger veins, in one case as early as forty-five minutes after death. The examination may be facilitated by dilatation with a mydriatic, which is possible several hours after death. Clouding of the cornea may be prevented or removed by instillation of distilled water.
