2. Abnormality of Binocular single Vision Confusion Diplopia Suppression ARC

3. Abnormality of Binocular single Vision Confusion: Confusion occurs when two different objects are seen in the same visual direction, commonly as a result of acquired strabismus.

4. Confusion F F

5. Abnormality of Binocular single Vision Diplopia: Diplopia (double vision) occurs when a single object is seen as two objects in different visual directions, commonly as a result of strabismus.

6. Homonymous (parallel) diplopia in esotropia with NRC F F

7. Abnormality of Binocular single Vision Suppression: Suppression is a binocular phenomenon resulting in the inhibition at the cortical level of the image from one eye. Suppression typically occurs as an adaptation to an anomaly of binocular vision, like strabismus or anisometropia

8. Esotropia with suppression F F N T

9. Anomalous Retinal Correspondence It is a sensoric shift in retinal correspondence so that previous non corresponding retinal elements start to work together and develop a common visual direction. Such a shift also implies a reordering of the visual cortex. This adaptation is thought to enable the development of a crude type of binocularity in the presence of Strabismus.

10. Binocular Single Vision The advantages of a Binocular vision are: The first and the foremost advantage of a binocular vision is single vision. In addition to single vision it results in stereopsis – the most precise kind of depth perception Enlargement of the field of vision Compensation for blind spot and other differences
