Clinical Profiles and Surgical Outcomes of Strabismus Following Orbital Wall Fractures: A Large Cohort From a Tertiary Eye Care Center.

Abstract

To evaluate the demographic details, clinical presentation, and surgical outcomes in patients presenting with strabismus following orbital wall fractures. A retrospective review was conducted over a 6-year period on 347 consecutive patients with strabismus who presented after orbital wall fractures. The patients were evaluated for their demographic data, clinical presentation, and profiles, management, complications, and outcomes of strabismus. Strabismus following orbital wall fractures was noted in 347 patients: 87.03% were men (n = 302) and 12.97% were women (n = 45). Fracture of the orbital floor in isolation or in combination with other walls was more frequently noted in 72.3% of patients (n = 251). The resultant strabismus included paralytic, restrictive, or both etiologies. Exotropia was noted most frequently in 25.65% of patients (n = 89), followed by exotropia with hypotropia in 20.75% of patients (n = 72). Ten percent of patients with strabismus (n = 34), who were observed for at least 6 months after injury, underwent surgical correction for strabismus. Preoperative diplopia was observed in 79.41% of patients (n = 27) and persisted after strabismus surgery in 15% of patients (n = 6). A successful outcome regarding the postoperative angle of deviation of 10 prism diopters or less horizontal and/or 5 prism diopters or less of vertical deviation with elimination of diplopia was observed in 41.17% of patients. Strabismus following orbital wall fractures is complex and requires a tailored strategy. The current study found the orbital floor to be more frequently involved in orbital wall fractures. However, the resultant strabismus was a combination of paralytic and restrictive etiologies. [J Pediatr Ophthalmol Strabismus. 2022;59(3):172-179.].
