A three-year-old baby with misaligned eyes may be caused by strabismus. It is necessary to go to the ophthalmology department of the hospital for an examination to clarify the type of strabismus, and then take targeted treatment. Adjustable strabismus can be corrected by wearing eyeglasses, and non-adjustable strabismus can be corrected by surgery. Depending on the type of strabismus, a three-year-old child with strabismus can be categorized into two types: adjustable strabismus and non-adjustable strabismus. Adjustable strabismus is usually accompanied by a refractive error, which can be corrected with glasses as prescribed by the doctor to balance the eye position and eliminate the strabismus. For non-adjustable strabismus, if the degree of strabismus is large, the patient can be corrected by strabismus surgery, such as extraocular muscle strengthening or extraocular muscle weakening, to correct the strabismus eye position. It is recommended that children with strabismus should seek prompt medical attention to evaluate their condition and undergo treatment under the guidance of a medical professional.
