Children with congenital myotrabismus will require surgery if conservative treatment is not effective or if they are older than the age of conservative treatment at the time of presentation. The accepted age for surgery is 1-2 years old, but beyond 2 years old, myotonic squint can lead to secondary deformities such as cheek asymmetry and eye strabismus. Moreover, these secondary deformities will continue to worsen with age, and even after surgery, it will be difficult for the child to return to normal after surgery, which will bring lifelong regret to the child. Therefore, parents are advised to contact the doctor promptly after their child is diagnosed with congenital myotrabismus and opt for surgery. Generally speaking, the younger the child is at the time of surgery, the younger the deformity secondary to the myotonic neck, and the better the surgical result.
