The exact cause of squint is not really known, the eyes need to be checked to see if they have any refractive error or Amblyopia; that may be responsible for squint. If there is any significant refractive error present, it needs to be treated first. Squint can be corrected anytime between 5-24 months of age with corrective surgery, preferably before 12 months. atment involves surgery for either one or both the eyes. The surgery would include weakening or strengthening of the relevant muscles to restore the balance and to get a good coordination. With early surgery, there will be better correction. The younger the age at which Amblyopia (associated with squint) is treated; the better is the chance of recovery of vision. In case of an adults, the surgery can only improve but not permanently cure (100% result is not possible). You and your child will need to be evaluated by an Ophthalmologist.
