Strabismus or squint or Crossed eyes

Strabismus is a condition of the eye in which the eyes are not aligned with each other. It occurs due to lack of coordination of the extra ocular muscles. It is also known as crossed eyes, Estropia, Exotropia, Wall eye

 

 

 

When the two eyes fail to focus on the same image, the brain will ignore the inputs from one eye. It is allowed over a period of time, the eye that the brain ignores will not be able to see well. This is called as amblyopia or lazy eye.

In strabismus the visual axes are not parallel to each other and hence the eyes appear to be looking at different directions.

If both the eyes are turned in it is called esotropia. If both eyes are turns out it is called exotropia. If the both eyes turn up it is called hypertropia. If both eyes turn down it is called hypotropia
