Patients with Parkinson's disease often face difficulties with reduced visual contrast acuity

Patients with Parkinson's disease (PD) often have difficulties with visual acuity in low-contrast images. Because they may have normal high-contrast vision, this is often overlooked during routine eye exams. In the current issue of the Journal of Parkinson's Disease, researchers report that PD patients had significantly worse vision for low-contrast images at close (40 cm) and far (2 m) distances. Even for high-contrast images, PD patients' vision was deficient at far distances.
