Analyzing the progression in retinal thickness could predict cognitive progression in Parkinson's patients

Although there are still some aspects pending confirmation for its use in the clinical setting, and its resolution needs to be improved slightly, a study has shown that a method routinely used to carry out ophthalmological tests can also be used to monitor the neurodegeneration that occurs in Parkinson's patients. In the course of the research it was found that the neurodegeneration of the retina probably precedes cognitive impairment.
