Traumatic rupture of the inferior rectus muscle: case report and review of the literature

Mona M Amer et al. Digit J Ophthalmol. .

Abstract

Traumatic inferior rectus muscle rupture secondary to blunt injury in the absence of associated orbital or ocular fractures or injury is rarely encountered, and there are limited published reports on subsequent surgical repair. We present the case of a 74-year-old man with complete inferior rectus transection following a fall with facial strike. A computed tomography scan of the face was unremarkable. Surgical exploration and repair of the muscle was performed by hooking the inferior oblique muscle to identify the inferior rectus muscle. Subsequent strabismus surgery was performed for residual binocular diplopia, resulting in excellent anatomic and visual outcomes and postoperative ocular alignment.
