Parkinsonism Relat Disord. 2015 Jul;21(7):797-9. doi: 10.1016/j.parkreldis.2015.04.014. Epub 2015 Apr 23.
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.
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.
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.
We provide evidence in favor of disrupted VEM in PD.
近视模糊是帕金森病（PD）患者常见的非运动症状，然而，目前缺乏对双眼视轴汇聚眼动（VEM）的详细特征描述。
使用红外视频眼动图技术对18例PD患者和18名对照者进行了集合和发散检查。分析的VEM指标包括垂直和水平平面上的潜伏期、速度和准确性。
PD患者的集合和发散潜伏期显著延长。此外，发散缓慢且测距不足，而其他集合指标与对照组相似。
我们提供的证据支持PD患者存在VEM障碍。
