Study Notes
Binocular Vision
- Binocular vision is the brain’s ability to combine images from both eyes into a single, unified image.
- Proper binocular vision requires synchronized movement of the eyes, accurate alignment of the eyes, and the ability of the brain to combine the separate images received from each eye.
- Binocular vision issues can occur due to problems with the anatomy of the visual system, the motor system that controls eye movements, or the sensory system which integrates information from the eyes.
- Anatomical abnormalities can be present from birth or develop later in life.
Motor System
- Fusional reserves refer to the ability of the eyes to move and converge to maintain single vision.
- Motor fusion refers to the act of fusing the two images together with the movement of the eyes, allowing for a single percept.
Sensory Fusion
- Sensory fusion refers to the brain's ability to blend the separate images from each eye to create a unified image.
- Fusion Lock occurs when the brain has successfully combined the images from both eyes into a single percept.
