Predictive value of computed tomography in visual outcome in indirect traumatic optic neuropathy complicated with periorbital facial bone fracture

This study reveals that posterior orbital fracture is associated with a worse prognosis in visual outcome than anterior orbital fracture, with visual improvement degree and percentage being 0.86 ± 0.17 log MAR and 34.2 ± 1.7% versus 1.56 ± 0.27 log MAR and 58.9 ± 1.7%, respectively (P = 0.02 and 0.004). Blow-in fractures such as an impacted lateral orbital wall did not predict significant deterioration in visual outcome. In addition, orbital floor or medial wall blow-out fractures did not predict significant improvement in visual outcome.
