What accurately describes Normal Correspondence (NC) in binocular vision?
What accurately describes Normal Correspondence (NC) in binocular vision?
- The state where each eye's visual direction is coordinated without deviation. (correct)
- A condition where one eye dominates in visual processing.
- The ability of both eyes to align properly at all times.
- A visual discrepancy where images from the two eyes are fused incorrectly.
Which of the following statements best defines Anomalous Correspondence (AC)?
Which of the following statements best defines Anomalous Correspondence (AC)?
- A situation where there is full binocular vision without any suppression.
- The eyes work together with no misalignment and perfect vision.
- A temporary visual condition caused by environmental factors.
- A form of visual perception where the dominant eye does not correspond with the non-dominant eye. (correct)
In the context of binocular vision, which scenario illustrates a misalignment of normal correspondence?
In the context of binocular vision, which scenario illustrates a misalignment of normal correspondence?
- Normal vision is restored through corrective lenses.
- Visual fields from both eyes overlap perfectly.
- Both eyes converge on an object but one eye perceives it differently. (correct)

Study Notes
Normal Correspondence (NC)
- Both eyes have a harmonious relationship.
- A single object is seen as one by both eyes.
- Fusion between projections of the object from both retinas occurs in the brain.
Anomalous Correspondence (AC)
- The eyes do not have a harmonious relationship.
- One eye dominates the other.
- The brain creates a single image by combining projections from retinal points which do not correspond in normal alignment.
Factors affecting the development of AC
- Age of onset and duration of strabismus.
- Angle of deviation.
- Type of strabismus.
- Treatment options.
Significance of AC
- AC can reduce the effectiveness of some treatment methods.
- AC can lead to a decreased ability to see in depth (stereopsis).
