Abstract:
The visual signal generated by the eye receiving external light stimulation reaches the visual center through the visual pathway and is processed and integrated by the visual center to form a subjective sensation called cerebral vision.Cerebral vision reflects the function of the whole visual nervous system from the retina to the visual cortex.Abnormal cerebral vision has been found in myopes using electrophysiology, magnetic resonance imaging (MRI) and functional near-infrared spectroscopy (fNIRS). The abnormal electrophysiological results are mainly found in patients with high myopia and pathological myopia.MRI shows abnormal changes in the structure and function of several vision-related brain regions in patients with high myopia.Recently, by applying near-infrared brain function imaging technology combined with self-developed equipment, our team conducted a series of studies on the brain function of myopic patients and found that adult patients with moderate myopia and patients with pathological myopia have the abnormal cerebral vision.The mechanism of neural regulation of eye accommodation in myopic children needs further investigation.In this article, we reviewed the current status and outlook of myopic brain vision research in terms of myopia classification, myopic brain vision research methods, and myopic visual electrophysiology, MRI, and fNIRS studies.
