Today, on World Brain Day 2020, we note that several neurodegenerative conditions, that affect the brain, including Parkinson’s Disease, exhibit ocular symptoms, and that the retina may be an accessible biomarker to monitor disease progression. Just as lifestyle, dietary and medical interventions can prove beneficial for retinal and neurodegenerative conditions, the benefits are greatest with early detection. With increasing knowledge and therapeutic interventions under development it essential that screening programmes are implemented to identify neurological conditions, and retinal exams may help with this.
