Prion diseases result from abnormal prion proteins accumulating in the brain. The proteins form lesions that can precipitate progressive neurodegeneration. One such condition of this type is Creutzfeldt-Jakob Disease or sCJD, which researchers believe can be passed on to patients receiving corneal grafts from the donor. Blindness will ultimately develop in up to 42% of sCJD patients.

The research team notes:

“Corneal grafts from prion-infected patients have led to two probably and three possible cases of iatrogenic prion transmission.”

These findings could guide scientists on the quest for developing early diagnostic tests for sCJD.
