“…The initial stages of visual perception are controlled by two parallel pathways (retinogeniculocortical pathways), namely, the magnocellular and parvocellular pathways, which each transmit different types of visual information ( 43 , 45 , 104 , 105 ). Physiological and behavioral studies have shown that the magnocellular pathway is most affected in HM, with patients showing impaired perception of motion and blue-yellow contrast ( 104 ). To date, there have been no reports on the neuroimaging of the retinogeniculocortical pathways in HM.…”

Dementia and cognitive impairment (CIM) carry high levels of mortality. Visual impairment (VI) is linked with CIM risk. High myopia (HM) is a chronic disease frequently leading to irreversible blindness. Current opinion has shifted from retinal injury as the cause of HM to the condition being considered an eye-brain disease. However, the pathogenesis of this disease and the manner in which neural structures are damaged are poorly understood. This review comprehensively discusses the relationship between HM, the central nervous system, and CIM, together with the novel concept of three visual pathways, and possible research perspectives.

“…Besides poor visual acuity, myopes also show abnormalities in spatial visual processing including contrast sensitivity (Stoimenova, 2007;Ehsaei et al, 2013), blur perception (Gwiazda et al, 1993;Rosenfield and Abraham-Cohen, 1999;Vasudevan et al, 2006;Maiello et al, 2017;Ang et al, 2020), color vision (Garcia-Domene et al, 2018), binocular vision (Vera-Diaz et al, 2018), and attention (Kerber et al, 2016). Myopes may also have abnormal temporal visual processing abilities.…”

“…Another study found that critical flicker frequency was lower in high myopes compared to emmetropes; and in a large range (5–60 Hz) of temporal frequency, the contrast modulation threshold of flickering stimuli was higher in high myopes ( Chen et al, 2000 ). A recent study using a psychophysical multichannel functional test ( Antón et al, 2012 ) to study the sensitivity of visual pathways in high myopes ( Garcia-Domene et al, 2018 ) found that the sensitivity of the magnocellular pathway, which is mainly responsible for the motion perception ( Merigan and Maunsell, 1990 ), decreased. Therefore, it suggested myopia may have impaired motion perception.…”

PurposeThe current study was to investigate whether myopia affected peripheral motion detection and whether the potential effect interacted with spatial frequency, motion speed, or eccentricity.MethodsSeventeen young adults aged 22–26 years participated in the study. They were six low to medium myopes [spherical equivalent refractions −1.0 to −5.0 D (diopter)], five high myopes (<-5.5 D) and six emmetropes (+0.5 to −0.5 D). All myopes were corrected by self-prepared, habitual soft contact lenses. A four-alternative forced-choice task in which the subject was to determine the location of the phase-shifting Gabor from the four quadrants (superior, inferior, nasal, and temporal) of the visual field, was employed. The experiment was blocked by eccentricity (20° and 27°), spatial frequency (0.6, 1.2, 2.4, and 4.0 cycles per degree (c/d) for 20° eccentricity, and 0.6, 1.2, 2.0, and 3.2 c/d for 27° eccentricity), as well as the motion speed [2 and 6 degree per second (d/s)].ResultsMixed-model analysis of variances showed no significant difference in the thresholds of peripheral motion detection between three refractive groups at either 20° (F[2,14] = 0.145, p = 0.866) or 27° (F[2,14] = 0.475, p = 0.632). At 20°, lower motion detection thresholds were associated with higher myopia (p < 0.05) mostly for low spatial frequency and high-speed targets in the nasal and superior quadrants, and for high spatial frequency and high-speed targets in the temporal quadrant in myopic viewers. Whereas at 27°, no significant correlation was found between the spherical equivalent and the peripheral motion detection threshold under all conditions (all p > 0.1). Spatial frequency, speed, and quadrant of the visual field all showed significant effect on the peripheral motion detection threshold.ConclusionThere was no significant difference between the three refractive groups in peripheral motion detection. However, lower motion detection thresholds were associated with higher myopia, mostly for low spatial frequency targets, at 20° in myopic viewers.
