Summary
Binocular vision develops with distinct stages, showing early competence but also unique processing mechanisms in children compared to adults. This research uses Visual Evoked Potentials (VEPs) to track this development.
Area of Science:
- Neuroscience
- Developmental Biology
- Ophthalmology
Background:
- Bilateral vision provides evolutionary benefits like expanded visual fields and depth perception.
- Understanding binocular vision development is crucial for identifying visual processing maturation in children.
Purpose of the Study:
- To review the developmental trajectory of binocular vision using Visual Evoked Potentials (VEPs).
- To explore key aspects of binocular vision development, including summation, masking, motion processing, and depth perception.
Main Methods:
- Analysis of studies employing Visual Evoked Potentials (VEPs) to assess binocular interactions.
- Review of research on binocular summation, dichoptic masking, intermodulation, developmental motion asymmetry, and sensitivity to retinal disparity.
Main Results:
- Early binocular vision exhibits distinct developmental patterns, including a 'developmental motion asymmetry'.
- Sensitivity to horizontal retinal disparity, a primary depth cue, develops over time.
- Children's binocular vision shows both early strengths and qualitative differences from adult processing.
Conclusions:
- Binocular vision development is characterized by distinct processing mechanisms and developmental sequences.
- VEPs provide valuable insights into the maturation of visual processing from infancy to adulthood.

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...
