A little slanting of the eyes is what is usually called strabismus, which may be caused by refractive errors, acquired diseases and so on, and can be corrected and treated by wearing glasses, surgical treatment and other ways. 1. Refractive error: when patients are in hyperopia, myopia, astigmatism, etc., if they are not corrected correctly or not corrected in time, it may lead to strabismus, especially when children are highly farsighted, many of them are accompanied by strabismus and amblyopia, and they have to wear glasses as early as possible to correct them. 2. Acquired diseases: If the acquired orbital fracture causes restrictive strabismus, it is necessary to repair the orbital fracture through surgery to release the pull on extraocular muscles, so that the strabismus symptom can be eliminated. If strabismus is caused by damage to the motoneuron due to acquired intraorbital hemorrhage or tumor, surgery is needed to remove the hemorrhage and resect the tumor to promote the recovery of the function of the motoneuron. Patients with strabismus are advised to go to the hospital in time for consultation and standardized treatment according to the doctor’s instruction after clarifying the cause of the disease.
