Sensory Eye Dominance: Relationship Between Eye and Brain

Area of Science:

• Neuroscience
• Ophthalmology
• Visual Science

Background:

• Eye dominance describes a preference for one eye during visual tasks.
• Motor and sensory eye dominance are distinct, with sensory dominance assessed via binocular rivalry.
• The divergence between motor and sensory eye dominance is not fully understood.

Purpose of the Study:

• To review recent advances in understanding sensory eye dominance.
• To explore the relationship between sensory eye dominance and other visual functions like stereopsis.
• To investigate the plasticity of sensory eye dominance.

Main Methods:

• Review of studies quantifying sensory eye dominance.
• Analysis of research correlating sensory eye dominance with stereopsis and visual functions.
• Examination of studies on the plasticity of sensory eye dominance.

Main Results:

• Sensory eye dominance is task-dependent and can differ from motor eye dominance.
• Sensory eye dominance in normal vision shares behavioral similarities with amblyopia, indicating interocular inhibition imbalance.
• Evidence suggests sensory eye dominance may manifest at multiple visual pathway levels.

Conclusions:

• Sensory eye dominance is a complex phenomenon potentially involving widespread neural mechanisms.
• Further high-resolution brain imaging is needed to confirm the neural basis of sensory eye dominance.
• Understanding sensory eye dominance may offer insights into visual processing and disorders.
