Trauma to the eye and orbit may cause fractures of the orbital wall, which can later cause strabismus and diplopia and seriously disrupt the patient’s life. Even with frequent orbital wall fracture repair surgery, many patients still have strabismus and diplopia that cannot be eliminated and require strabismus surgery for correction. This is also because this type of strabismus is often non-common. For example, while the diplopia may be light in the front, it is significantly worse when looking downward. This increases the difficulty of correction. We have adopted and improved on some of the advanced experience from abroad in treating these cases, and have treated a large number of these patients with good results. For example, in the following patient: Before surgery, he could only cover one eye because of diplopia. The diplopia was aggravated in the lower side and he could not walk. The eye position in all directions, noting that the downward looking left eye was not going down After the surgery, the eye movement was free and the diplopia disappeared in all directions. Note that the downward motion is also balanced. Because we have accumulated a relatively large number of such patients, we summarized an article published in a professional ophthalmology journal and also spoke at an ophthalmology conference to introduce these methods to our colleagues. We hope that patients with strabismus after post-traumatic orbital wall fractures understand that both diplopia and strabismus can be improved.
