Diplopia Secondary to Orbital Surgery

Abstract

Diplopia may occur following any type of ocular or periocular surgery. The surgeries most frequently associated with postoperative diplopia include: repair of orbital fracture, endoscopic sinus surgery (from inadvertent orbital penetration), and orbital decompression for thyroid-related immune orbitopathy (TRIO). Postoperative diplopia after orbital tumor resection has been reported—e.g., after excision of fibrous dysplasia and osteoma.¹ However, a recent case series suggests diplopia after orbital tumor resection is uncommon and transient.² Surgical intervention for orbital trauma carries the highest risk of postoperative diplopia and will be the focus of this review. We will also present a case report of worsening diplopia following repair of orbital floor fracture to highlight potential motility issues that can arise when implants are employed to treat orbital floor fractures.
