CT Based Three-Dimensional Measurement of Orbit and Eye Anthropometry

Abstract

The comprehensive set of measurements collected in this study provides three-dimensional information on orbit geometry, as well as placement of the eye within the orbit. These measurements and the methodology used will contribute to the development of finite element models of the orbit and eye for computational modeling purposes and may be useful in the design of eye protection equipment.

Anthropometric measurements of the orbita and gender prediction with three-dimensional computed tomography images

“…In the present study we have found that the orbital height, width, orbital index, biorbital-interorbital widths were higher in males than in females. According to the study of Weaver et al [10], similarly to our study, the orbital width and height in males were found to be higher than in females. Furthermore, Husmann et al [2] in their study found that the orbital index is higher in females.…”

“…Orbits have been used in race and gender prediction of individuals for more than a century [10]. Understanding human anatomy, proportions, mechanical functions and racial variations concerning the ocular anatomy are of vital importance when treating or clinically evaluating patients [2].…”

Silicon-Integrated High-Density Electrocortical Interfaces

“…Thus far, titanium-, glass-or ceramicbased enclosures have been the primary means for hermetic sealing in long-term implants, since these hard materials have been shown to be biocompatible and impermeable to water [181]. Even though such hard enclosures are used in the majority of long-term implants [6], [111], [122], [150]- [155], [159], [183], their very large volume and weight, typically much larger than the ICs and supporting components they contain, prohibits their use in high-dimensional neural interfaces heavily constrained by anatomical space such as retinal prostheses [184] and ECoG arrays [30]. In addition, hard packaging requires intricate methods for hermetic sealing of feedthroughs to polymer insulated extensions of the implant such as electrode array cabling, limiting the density of electrode channels due to feedthrough channel spacing requirements.…”
