BACKGROUND: Blurred near vision is a common non-motor symptom in patients with Parkinson's disease (PD), however detailed characterization of vergence eye movements (VEM) is lacking. METHODS: Convergence and divergence were examined in 18 patients with PD and 18 control subjects using infrared video-oculography. VEM metrics analyzed included latency, velocity and accuracy, in vertical and horizontal planes. RESULTS: The latency of convergence and divergence was significantly increased in PD subjects. Additionally, divergence was slow and hypometric, while other convergence metrics were similar to controls. CONCLUSION: We provide evidence in favor of disrupted VEM in PD.
