Functional success: 0.1 or better.

VA = visual acuity, BETTS = Birmingham Eye Trauma Terminology System, OTS = Ocular Trauma Score, BOF = blow-out fracture, RAPD = relative afferent pupillary defect.

^aP values were calculated using χ² and Fisher's exact test as appropriate, from non-missing data.
