Why is squint correction done?
Squint correction is a surgery done to correct the misalignment of eyes due to congenital or acquired conditions. There are many forms of squint such as
- Esotropia or crossed eyes with one eye turned inwards, towards the nose
- Exotropia or wall eye/horizontal deviation with one eye turned outside, towards the temple
- Hypertropia or vertical deviation with one eye turned upward, towards the eyebrow
How is squint correction done?
- The eye is rotated and the conjunctiva cut open to expose the muscle which is either
- weakened by recession of muscles - detaching it from the eye and reattaching it further back on the eye with a suture or
- strengthened by resection - the muscle from the eye is detached, its distal end excised, and then reattached to the eye, with a suture.
- Either process is repeated for each muscle that is operated on.
