Common childhood vision disorders that occur during a critical period of visual system development

The incidence rate among the population is 3.9%

Refractive error

strabismus

form deprivation

Crowding

Loss of stereopsis

Impaired contrast sensitivity

Spatial positioning affected

Shape and motion perception affected

Unsteady gaze

selective visual attention deficit

Visual motor coordination deficits

Elevated contrast sensitivity threshold

Increased brightness threshold

Shape and motion information are suppressed

Eye movement training

May result from severe visual impairment

Improved sensory perception or executive performance resulting from practice, achieved through repeated exposure to certain stimuli or repeated performance of certain physical tasks

Repeated stimulation leads to strong and synchronous activation of certain cell populations along neuronal pathways, mediates specific neurosensory tasks, and promotes synaptic strengthening between these neurons

Permanent neuroplastic changes through training that improve neurosensory responses

The effectiveness of PL in shaping neuroplasticity in the visual cortex and subsequently in rebalancing the dominant eye was demonstrated in patients with amblyopia through changes in steady-state visual arousal potential (SSVEP) amplitude measured before and after multiple treatments.
