"Predicting Parkinson's Progression with Eye Tests"

Optical coherence tomography, commonly used in eye exams, can monitor neurodegeneration in Parkinson’s disease patients by measuring the thickness of the retina, which often precedes cognitive and motor decline. This method offers a potential early indicator of disease progression, suggesting that routine eye exams could become a non-invasive tool for predicting the future severity of Parkinson’s symptoms and aiding in more targeted treatment strategies.
