Orbital HRCTEndoscopic viewMissing rate (%)
Displaced OCF with impingement2642640
Displaced OCF without impingement37442551 (12%)

No OCF567380
  • Missing rate=(Number of patients missed out by HRCT scans)/(Number of patients confirmed during surgery).

  • HRCT, high-resolution computed topography; OCF, optic canal fracture.
