Individuals with Parkinson’s disease present with reduced thickness of two key components of the retina, which may indicate retinal optical coherence tomography as a vital tool in early disease detection, data show.
“Stimulated by the postmortem finding of reduced dopamine content in the retina of people with Parkinson’s disease, researchers have sought evidence of retinal changes on in vivo imaging techniques, such as optical coherence tomography,” Siegfried Karl Wagner, MSc, MD, of the Institute of Ophthalmology at University College London, and colleagues wrote in
