Eye Squint (Strabismus)published on: 14th march, 2023
What is Eye Squint or Strabismus?
Eye Squint or Strabismus is also referred to ocular misalignment or misalignment of the eyes which may occur at any age. Misalignment refers to the eye which are not lined up to look at the same thing wherein one eye is fixed to on what the person intends to look at the (fixing eye) and the other eye is looking at something else (the deviated eye). While it has been regarded as failures of development from birth, it has been noted to begin when an individual reaches two and a half to three and a half year period; with its peak of incidence during the second to fifth years.
What are the effects of Eye Squint or Strabismus to one's vision?
- Very rarely seeing of 2 different objects in the same place or images appear to merge into one another, a condition termed as Visual Confusion.
- More commonly, for cases of acute squint, two images double/image is seen. One image is from the fixing eye which appears normal and the image from the deviated eye usually appears blurred.
- For longer standing squint, the second or blurred image as seen by the deviated eye is ignored or suppressed by the brain.
- Reduced depth perception.
- Amblyopia or lazy eye.
What are the forms of Eye Squint or Strabismus?
- Cross-eyed (Esotropia)
- Wall-eyed (Exotropia)
- Upward deviation (Hypertropia)
- Downward deviation (Hypotropia)
What are the causes of Eye Squint or Strabismus?
- Congenital tendency for the eyes to deviate.
- Defective nerves or muscles because of different reasons.
- Farsightedness (Hypermetropia) and need for spectacles.
- Serious disease affecting the nervous system or eye.
What are the benefits of treatment-optical/surgocal to starighten the eye vision?
- Development or restoration of binocular vision or binocular depth perception.
- Elimination of double vision.
- Restoration of normal head posture
- Increased visual field.
- Creation of normal appearance
