Inferior Rectus Muscle

Orbital complications are known risks of endoscopic sinus surgery (ESS). The lamina papyracea and medial rectus muscle are the most commonly injured structures during ESS. Inferior rectus injury is more rare, with only one reported case of isolated inferior rectus injury in the literature. Guidelines for managing ESS-induced inferior rectus injury do not exist, and delayed intervention and management of adjacent sinuses may affect long-term outcomes such as persistent diplopia and disfigurement. In this report, we present a case of a 67-year-old man with diplopia due to isolated left inferior rectus muscle entrapment and injury from violation of the orbital floor during previous ESS. We postulate that an incomplete maxillary antrostomy contributed to scar band formation and entrapment of the inferior rectus muscle after the orbital floor was violated, and advocate early intervention with a wide, complete maxillary antrostomy if the orbital floor is injured during ESS.

Inferior Rectus Muscle

The aim of this study was to evaluate the incidence, clinical features, and risk factors of sustaining inferior rectus (IR) palsy in a group of pediatric patients with orbital floor blowout fractures. We performed a retrospective case review of sequential cases of pediatric orbital floor blowout fractures (<18 years old) from 2000 to 2013 in a tertiary ophthalmic center in Singapore. A total of 48 patients were included in our study, of whom 5 had IR palsy (10.4%). Patients with IR palsy had a higher mean age (16.4 ± 1.5 years) compared with patients without IR palsy (12.4 ± 3.3 years), had significantly ( p < 0.05) worse preoperative motility, and had significantly greater proportion developing postoperative hypertropia (100%) compared with patients without IR palsy (4.7%). Our series of pediatric blowout fractures demonstrated IR palsy prevalence and clinical features for IR palsy which may be distinct to the pediatric group.

Inferior Rectus Muscle

Orbital floor fractures (OBF) account for 40% of mid-facial injuries and are therefore the most common of all trauma injuries in this region. The post-treatment complication that often follows orbital floor repair is residual diplopia or 1 persistent diplopia and is seen in 86% of the OBF cases. The causes for persistent diplopia can be varied and is often related to the degree of inflammation, trauma to 2 musculature, fat or nerves and surgical timing. Some of the common causes of the same are - malpositioning of the globe, fibrosis of the inferior fibro fatty muscular complex following trauma, direct damage to an extraocular muscle (commonly inferior rectus muscle), local injury to a motor nerve, ischemia (or compartment syndrome), iatrogenic damage during reconstructive surgery or entrapment under improperly placed alloplastic material. Our case report mentions a rare case of persistent vertical diplopia even after successful repair of orbital blowout fracture. A 15-year-old male patient following a road traffic accident presented with persistent headache and vertical diplopia. The patient was evaluated by a oral maxillofacial surgeon and a presumptive diagnosis of a case of large orbital floor fracture with entrapment of inferior rectus muscle was made which was confirmed on CT Scan. He was managed surgically by reduction of the fracture and fixation with a titanium mesh. 2 weeks post-surgery he reported to the squint clinic with complaints of persistent double vision. On comprehensive ocular examination, it was found that patient had vertical diplopia with limitation of infraduction in the left eye with negative FDT, on re-evaluation of MRI scans with 1 mm cuts, a partial left inferior rectus tear was seen and documented as the cause of persistent diplopia. Patient was treated conservatively by prescribing prismatic glasses with fusional exercises. After 6 months of follow up, the patient was relieved of diplopia in primary position but there was a residual hypotropia in downgaze for which he was prescribed prisms only for downgaze.
