Objective To explore the specific etiology and management of acquired paralytic strabismus.Methods Clinical data from 3 cases of acquired paralytic strabismus in children were retrospectively analyzed.Results All 3 patients were children who experienced sudden onset of the disease and presented with obvious eye movement disorders;they were diagnosed as paralytic strabismus,with different causes of onset and systemic accompanying symptoms.The child with malignant tumor of mesenchymal origin showed significant improvement in symptoms after tar-geted treatment,with the right eye in normal position and slight restriction in outward rotation,without diplopia;the patient with otitis media showed normal position of the right eye and no ob-vious restriction in outward rotation after 17 days of anti-infective treatment,without diplopia;the patient with myasthenia gravis showed significant improvement in symptoms after symptom-atic treatment,with minimal ptosis in both eyelids,slight restriction in downward rotation of the left eye,and normal outward rotation.Conclusion The causes of acquired paralytic strabismus are complex and variable,and may be accompanied by systemic or neurological abnormalities.Certain diseases presenting with paralysis of extraocular muscles are often first diagnosed as paralytic strabismus,and identifying the cause may be helpful in formulating appropriate clinical treatment plan.
