Abstract

Accurate population and sex-specific normative values for the orbital and ocular dimensions, including the position and protrusion of the eye relative to the orbital rim, are vital for reliable facial approximations. In studies utilizing cadaveric tissue and computed tomography scans, the observed measurements may be influenced by desiccation, distortion or gravity, respectively. This study assessed the dimensions of the eye and orbit and established the position and protrusion of the eye relative to the orbital margin using cone beam computed tomography (CBCT) scans to negate the effect of gravity in the supine position. Scans of 197 adult South Africans (45 Black females, 49 Black males, 55 White females, and 48 White males) were selected retrospectively from private and public hospitals in Pretoria, South Africa.
