摘要:

We adapted a Nikon camera body without a built-in mask to the Kowa RC-W retinal camera in combination with the Komura Telemore 95 2 × magnification accessory attachment. This way we obtain finer detail retinal photographs taking the complete image field of 24 × 36 mm on the film into consideration. The negatives or slides are large enough to be read without the use of a magnifier. Most other systems have a smaller field of view at higher magnification, because of built-in masks.

摘要:

In order to find a successor for the Hardy, Rand and Rittler (AOH-R-R) test the author made a comparison between the AOH-R-R and the Tokyo Medical College (TMC) tests in acquired dyschromatopsia. The diagnosis of the TMC type of a red-green defect is often in contradiction with the results of other color vision tests. In grading the severity of a red-green defect the TMC classification is shifted with regard to the AOH-R-R classification. A corrected grading in better agreement with the AOH-R-R classification is proposed. The TMC blue-yellow screening plates are more sensitive than the AOH-R-R blue-yellow screening plates. A TMC (supermild) blue-yellow defect in general corresponds to blue-yellow defects detected by FM 100 Hue and its derivatives. In the study of acquired dyschromatopsia, it is necessary to use a test battery. In our opinion the TMC can be used in such a test battery although it is not a real successor to the AOH-R-R. If ever the AOH-R-R is reprinted, the blue-yellow plates should be extended to a ‘supermild’ degree as are the TMC blue-yellow plates.

摘要:

In 13,440 bacteriological investigations the effectivity of different methods for desinfection of Goldmann tonometer prisms (merfen, pantasept, sekusept steril, UV sterilizer Sklar) is tested. Sekusept steril and UV sterilizer show the quickest and most sufficient results. They cause no damage to corneal epithelium or to plastic objects. We can recommend them for desinfection of applanation tonometer prims, Goldmann’s gonioscopy and fundus contact lenses as routine methods.

摘要:

The results of pseudoisochromatic tests (TMC Ishihara, AOH-R-R) are relatively independent of age. In the Panel D-15, the NCT box 6/4 and the desaturated panel, ageing goes hand in hand with blue-yellow confusions. Fault-positive red-green confusions result from D8/2 examination. For the FM 100 Hue test and the Anomaloscope Nagel, the data found in the literature are confirmed. In nuclear cataract there is no increased shift of the Rayleigh equation towards the green, but towards the red.

摘要:

Ocular involvement was found in 29 autopsied individuals with generalized vascular amyloidosis. It may be present both in clinically primary and secondary amyloidosis. In the latter form the choroid and the sclera are particulary involved, whereas in the orbit the most frequently affected tissues in both forms are the extraocular muscles. However, in most cases amyloid deposits are localized in the vessels of the aterial circle of Zinn-Haller. The retina showed no involvement in 28 of 29 cases while optic nerve fibres never were affected. The optic nerve dural sheath was slightly involved in 8 cases.

摘要:

Various dosages of the anticancer agent 1,3-bis(2-chloroethyl)-1-nitrosourea (carmustine, BCNU) were administered to 28 normal rabbit eyes. Single injections and series of injections were given to determine the tolerance and toxicity levels of this drug when injected directly into the vitreous cavity, the anterior chamber, or the subtenon-retrobulbar space. During a follow-up period of 3 weeks to 4 months, no significant ocular changes were noted following a single injection of BCNU into the vitreous (0.002–0.50 mg) or anterior chamber (0.001–0.250 mg), or 10 daily subtenon-retrobulbar injections (0.5–1.0mg each). When the daily dosage was increased to 1.5–2.0 mg, corneal damage with stromal infiltration, edema, and vascularization were found after the course of the 10 subtenon-retrobulbar injections in 3 of 6 test animals.

摘要:

After successful surgery for retinal detachment, a series of functional tests was performed, which primarily concerned the contact between photoreceptors and pigment epithelium. Even several months after reattachment the EOG still remained lower than in the fellow eye, when the macula was involved. If maximal visual acuity was reached with a formerly detached retinal area, the photostress recovery time was found to be delayed. The decoupled ERG showed distinct impairment of the c-wave in the eye with the reattached retina.

摘要:

Rebound nystagmus represents a disorder of ocular motility, encountered in patients with chronic cerebellar lesions. The case history of a 34-year-old patient suffering from cerebellar degeneration is introduced briefly, and the oculographic features of rebound nystagmus are discussed with special remarks on the problems, tracing this kind of ocular motor disturbance.
