Strabismus can be caused by a variety of reasons, congenital developmental abnormality is the most common reason, refractive error can also cause strabismus, eye trauma or central nervous system lesions are triggering factors for strabismus. Different types of strabismus are treated differently. Adjustable strabismus caused by refractive error can be corrected by accurate optometry and glasses, and the symptoms of strabismus can be eliminated. Other types of strabismus usually require surgery. Patients need to go to the ophthalmology department of the hospital for strabismus-related examinations, such as corneal reflectometry, masking and de-masking tests, and trismus tests, to determine the type and severity of strabismus, and then the doctor will formulate a treatment plan. If strabismus is detected, it is recommended to consult a doctor promptly and follow the doctor’s instructions.
