Question

Question 13 2.5 pts Strabismus is a childhood eye disease in which children cannot align their eyes properly (it is also called 'lazy eye'). Children with this condition typically stop using one of their eyes to avoid double vision. Use several paragraphs to explain the basis of binocular vision, how strabismus affects the representation of input into the visual cortex, and what happens if the disease is not corrected?

The question is been asked from a Neurobiology stand point.....

Answer 1

Answer:

Strabismus result in mono-ocular blurred retinal image. This causes dissimilar images to fall on corresponding retinal areas.

The images cannot be fused. Result in adaptation of visually immature eye, by inhibiting cortical activity from blurred eye or deviated eye.

This is because binocular vision is not inborn. In first 3 years of life, the binocular input into cortex makes, the neurons in that area of cortex develop.

In young patients sensory adaptation overcome diploid and confusion.

Sensory adaptation are

a) suppression

b) abnormal retinal correspondence. ARC

ARC

Here shift in spatial localization from deviated eye, helps to develop binocular vision.

Convergence of nerve fibres from here means, it lost point to point correspondence.
