研究目的:

本研究旨在明确大脑视觉中枢是否以及如何参与屈光参差的形成及其向弱视发展的机制,系统评估屈光参差及屈光参差弱视患者视觉中枢和视网膜结构与功能的异常特征,通过多模态脑影像(OPM-MEG)与眼部OCT、OCTA等技术,联合系统评估大脑视觉中枢、眼部结构及视觉功能的多层次变化,探讨三者之间的动态关联。研究目的在于揭示大脑视觉中枢是否及如何主导或参与屈光参差形成及弱视发生,同时明确其通过调节眼部结构和功能影响视觉发育的机制,并且发现能够预测屈光参差性弱视发生的早期中枢或外周联合生物标志物,并为理解屈光参差的神经生理机制提供新的视角。  

Objectives of Study:

The present study is designed to investigate the role of the cerebral visual cortex in the formation of anisometropia and the subsequent development of amblyopia. Utilizing multi-modal neuroimaging techniques, including optically pumped magnetometer-based magnetoencephalography (OPM-MEG), in conjunction with ophthalmic technologies such as Optical Coherence Tomography (OCT) and OCT Angiography (OCTA), this research will systematically assess the abnormal characteristics of both structure and function within the visual cortex and retina of patients with anisometropia and anisometropic amblyopia. A key objective is to examine the dynamic associations among the central visual pathway, ocular structures, and visual function. The study aims to reveal whether and in what manner the visual cortex directs or contributes to the pathogenesis of anisometropia and the onset of amblyopia, and to delineate the mechanisms by which it regulates ocular structures and functions, thereby impacting visual maturation. Furthermore, this investigation endeavors to identify early-stage central and/or peripheral biological markers predictive of the development of anisometropic amblyopia, offering new perspectives on the underlying neurophysiological mechanisms of anisometropia.

Measure method:

OCT/OCTA Measurement Method The patient rests their chin and forehead on the device and gazes at an internal fixation target. The instrument directs near-infrared light to rapidly scan the fundus (e.g., the macular region). OCT (Optical Coherence Tomography): Analyzes back-scattered light to generate real-time, high-resolution cross-sectional retina images, clearly delineating its structural layers. OCTA (OCT Angiography): Detects signal changes caused by red blood cell movement between successi

Measure method:

mfERG Measurement Method Following topical anesthesia of the eye, a recording electrode (e.g., a DTL fiber) was placed on the cornea. The participant fixated on a monitor displaying a hexagonal array, where each element flickered independently according to a pseudo-random sequence. The system simultaneously recorded electrical responses from multiple retinal locations, generating a topographic map that quantitatively assesses local retinal function.
