A Comprehensive Dataset of Pattern Electroretinograms for Ocular Electrophysiology Research: The PERG-IOBA Dataset
收藏资源简介：
The pattern electroretinogram (PERG) is a valuable tool in ophthalmic electrophysiology, offering a non-invasive and objective method to evaluate central retinal function. By measuring electrical activity in the macula and retinal ganglion cells, PERG provides essential quantitative insights, especially when distinguishing between macular and optic nerve diseases remains challenging. This dataset comprises 1354 transient PERG responses from 304 subjects in 336 records, representing a comprehensive collection of ocular electrophysiological data. The evaluations took place at the Institute of Applied Ophthalmobiology (IOBA) at the University of Valladolid, Spain, from 2003 to 2022. Detailed clinical information, including age, gender, and diagnoses, is provided in CSV format. Additionally, the dataset, which guarantees the presence of at least one PERG signal for each eye, incorporates visual acuity measurements in logMar scale, facilitating assessments of vision quality. Addressing a significant gap in ocular electrophysiological signal repositories, this dataset serves as a valuable resource for the advancement of ophthalmology research. Researchers can explore a wide range of eye-related conditions and diseases, leading to improved diagnostic techniques, treatment strategies, and a deeper understanding of ocular electrophysiology.
模式视网膜电图（pattern electroretinogram, PERG）是眼科电生理学领域极具价值的工具，可为视网膜中心功能评估提供无创且客观的检测手段。通过测量黄斑区与视网膜神经节细胞的电活动，PERG可提供关键的定量分析依据，尤其在区分黄斑病变与视神经疾病存在较大难度时，其应用优势更为突出。本数据集包含来自304名受试者的1354个瞬态PERG响应信号，共计336条记录，是一套覆盖全面的眼电生理学数据集合。该数据采集自西班牙巴利亚多利德大学应用眼科学研究所（Institute of Applied Ophthalmobiology, IOBA），采集时间跨度为2003年至2022年。详细的临床信息（包括年龄、性别与诊断结果）以CSV格式提供。此外，本数据集确保每只眼均至少包含一条PERG信号，同时纳入了以logMar量表记录的视力测量数据，可辅助视力质量评估。针对当前眼电生理学信号数据库存在的显著研究缺口，本数据集可为眼科研究的发展提供宝贵的资源支持。研究人员可借此开展各类眼部相关病症与疾病的相关研究，助力优化诊断技术、完善治疗策略，并加深对眼电生理学的认知。
