New prion assay suggests ophthalmic surgical instruments could transmit vCJD

(CIDRAP News) – A new immunoblot method for detecting prion protein related to variant Creutzfeldt-Jakob disease (vCJD) is much more sensitive than existing bioassay techniques, according to a recent report in The Lancet. The new assay revealed significant amounts of prion protein in the eye tissue of vCJD patients, prompting researchers to suggest that ophthalmic surgical instruments may pose a risk of transmitting the disease.
