Moderate effective=IDVA no more than 50%; very efficient=IDVA≥50%; ineffective=no improvement of VA after surgery.
P=difference of efficacy between patients with OCF and no OCF, using χ2 test.
IDVA, improvement degree of VA; No OCF, patients who did not have OCF; OCF, optic canal fracture; VA, visual acuity.
