Gaze and Eye Movement Data in Orthostatic Hypotension Study for Parkinson’s Patients

This dataset contains detailed eye-tracking measurements from patients with Parkinson’s disease (PD) who participated in a study on orthostatic hypotension (OH). Data were recorded as patients performed a series of gaze tasks, focusing on an object positioned first on the ceiling and then on the wall, repeating this process through three sequences of lying down and sitting up. The objective was to assess eye movement characteristics, gaze stability, and pupil dynamics under repeated orthostatic challenges. This study aims to investigate the relationship between PD, OH, and potential oculomotor and autonomic nervous system impairments.本数据集收录了参与体位性低血压（orthostatic hypotension, OH）研究的帕金森病（Parkinson’s Disease, PD）患者的详细眼动追踪测量数据。数据采集于患者完成一系列凝视任务的过程中：受试者需先注视天花板上的视觉目标，随后转向注视墙面目标，并通过三次躺卧-坐起的循环重复该操作流程。本次研究的核心评估目标为：在反复体位应激条件下的眼动特征、凝视稳定性及瞳孔动力学变化。本研究旨在探究帕金森病、体位性低血压与潜在眼动及自主神经系统损伤三者之间的内在关联。
