Question
An 8-year-old patient was diagnosed with left eye optic nerve atrophy, suspected to be caused by a fever at birth, and has no family history. The patient’s right eye is normal, but the left eye has an exotropia due to a field defect in the left eye. The patient has undergone strabismus surgery, but the results were poor and it quickly relapseed, with the exotropia being particularly noticeable at a distance, while it is almost unnoticeable at close range. Is there a possibility of inheritance for this type of optic nerve atrophy? Can strabismus caused by optic nerve atrophy also be inherited?
Answer
Strabismus can be classified according to the direction of deviation as esotropia, exotropia, hypertropia, and hypotropia, with esotropia and exotropia being the most common. The treatment methods for strabismus include wearing glasses, prism treatment, medication, strabismus training, and surgical treatment. For adults with strabismus, surgery is currently the only option to achieve cosmetic correction and achieve binocular alignment.
