title: Asymmetry of retinal lesions in experimental scrapie after intracerebral inoculation of hamsters.
abstract: Hamsters injected into the right cerebral hemisphere with the scrapie agent developed retinal lesions to a greater extent in the contralateral than in the ipsilateral eye. This asymmetry was evident during the incubation period as well as during the clinical encephalopathy. The results explain much of the variation in the degree of retinal disease seen earlier at specific times after inoculation. Moreover, they strengthen the hypothesis that scrapie spreads via neurons.
