Visual aspects of Creutzfeldt-Jakob disease

Richard A. Armstrong

Research output: Contribution to journalArticlepeer-review


In recent years, a number of diseases believed to be caused by proteinaceous infectious agents called 'prions' have been described and collectively referred to as the 'transmissible spongiform encephalopathies'. Prions, which are composed mainly of protein, differ significantly from other infectious agents such as bacteria and viruses. However, they may, and have been reported to, cause visual symptoms, whilst the possible transfer of prions through optometric procedures has also been the subject of much debate. This article discusses the relevance of prions to optometric practice.
