PSB: primary scleral buckling; IOFB: intraocular foreign body; BDVA: best distance visual acuity; OTS: ocular trauma score; logMAR: logarithm of the minimal angle of resolution. Continuous and ordinal variables were analyzed using Mann-Whitney test. Binary variables were analyzed using trend test or Fisher’s exact test.
