Figure 1: (a) Graphical representation showing bones forming orbit: yellow = frontal bone, green = lacrimal bone, pink = ethmoid bone, blue = zygomatic bone, orange = maxillary bone, red = sphenoid bone, aqua = palatine bone. Note a bony defect in posterior aspect of left orbit due to the absence of left sphenoid wing giving the “Empty orbit sign.” (b) Plain radiograph AP view. (c) CT surface shaded display image. (d) Axial CT scan demonstrating orbits
