Those diagnosed with strabismus have mis-aligned eyes, due to lack of coordination between the extraocular muscles. This can lead to improper double vision. Our ophthalmologist here can help correct this with a combination of eyeglasses, vision therapy and surgery.
What is Strabismus?
Strabismus is used to describe the disorder where the eyes do not line up together in the same direction. Six different muscles surround the eye and work together to ensure both eyes can focus on the same object. In someone with strabismus, these muscles do not work together. As a result, one eye looks at one object, while the other eye turns in a different direction and is focused on another object. The squinting eye can turn inwards (convergent), outwards (divergent), up or down. When squinting occurs, two different images are sent to the brain, one from each eye. This confuses the brain, and the brain may learn to ignore the image from the weaker eye. Someone with strabismus may also experience difficulty with depth perception.
Types of squints:
The most common types of squint are as follows:
Strabismus can also be seen in adults when there is presence of other disorders such as, brain & nerve disorder, diabetes, injuries to eye and tumor in the eye or brain.
What are the implications of a squint?
Amblyopia (lazy eye) – If a child develops a squint he/she ‘switches off’ the eye that turns to avoid experiencing improper double vision. If left untreated the vision can deteriorate and result in amblyopia, also known as lazy eye.
