Fig 2. Measurement of orbital height, width and depth.

Orbital width was the length of line AB. ‘A’ represented ectoconchion, and ‘B’ represented dacryon. Orbital height was the length of line CD. ‘C’, ‘D’ were the junctions of the midnormal of line AB with the superior and inferior orbital rims. Orbital depth was the distance between the lateral rim of the optic canal and the midpoint of the inferior rim. ‘E’ represented the lateral rim of the optic canal.
