Management of traumatic globe subluxation with optic nerve and extraocular muscle transection.

Abstract

A care algorithm for partial globe subluxation cases with optic nerve and at least one extraocular muscle (EOM) transection is presented after a literature review was performed using key term variations of globe, ocular, subluxation, optic nerve evulsion or transection, and trauma. Partial globe subluxation cases with transection of the optic nerve and at least 1 EOM were included. Exclusion criteria included globe rupture, complete enucleation defined by a globe without at least 1 EOM attachment, or unclear details confirming optic nerve transection. Including the patient presented herein, a total of 24 patients with 26 eyes were analyzed. About 73.08% of cases underwent initial repositioning (n = 19), with 11.54% of those requiring secondary enucleation or evisceration (n = 3). Of the secondarily managed cases, 2 of the 3 cases listed pain (n = 2) and inadequate cosmesis (n = 1) as rationale. We found that 26.92% of cases underwent initial enucleation (n = 7), citing lack of visual potential and limiting later complications. Most cases favored repositioning, which was typically sustainable. Initial repositioning can improve cosmetic outcome and psychological impact. Given the low risk of later management, cases of traumatic partial subluxation with EOM and optic nerve transections should attempt initial repositioning.
