BCVA = best corrected visual acuity; n = number of patients; IOFB = intraocular foreign body; RAPD = relative afferent pupillary defect; zone of injury (according to Birmingham Eye Trauma Terminology– BETT classification of ocular trauma): 1 = trauma involves cornea and limbus; 2 = extending posteriorly from the limbus up to 5 mm into the sclera; 3 = extending posteriorly more than 5 mm beyond the limbus; OTS category (sum of raw points): 1 = 0–44; 2 = 45–65; 3 = 66–80; 4 = 81–91; 5 = 92–100
Bold results indicate a significance level of P < 0.05
