Head trauma can injure the afferent and/or efferent visual systems, resulting in neuro-ophthalmic deficits. When assessing afferent pathway injuries, a stepwise approach to evaluating visual acuity, pupils, color perception, and visual fields is critical. Traumatic optic neuropathy is of especial importance and its management must be tailored on a case-by-case basis. Efferent pathway injuries should be assessed with attention to abnormalities of ocular alignment and motility, which may occur as isolated deficits or as part of a recognizable syndrome. Concussion or diffuse axonal injuries may also affect ophthalmologic function. Here, we review the extant literature describing the assessment and acute treatment of traumatic neuro-ophthalmic deficits.
The overall risk of severe vision loss after orbital surgery is 0.84%. The subgroup risk is higher in patients undergoing facial polytrauma repair, optic canal decompression, or orbital apex surgery from an intracranial approach. Close postoperative monitoring and urgent assessment and management of acute vision loss may improve visual outcome in some patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
