On variational solutions for whole brain serial-section histology using a Sobolev prior in the computational anatomy random orbit model.

PLoS Comput Biol 2018 Dec 26;14(12):e1006610. Epub 2018 Dec 26.

Center for Imaging Science, Department of Biomedical Engineering, Johns Hopkins University, Baltimore, MD, USA.

This paper presents a variational framework for dense diffeomorphic atlas-mapping onto high-throughput histology stacks at the 20 μm meso-scale. The observed sections are modelled as Gaussian random fields conditioned on a sequence of unknown section by section rigid motions and unknown diffeomorphic transformation of a three-dimensional atlas. To regularize over the high-dimensionality of our parameter space (which is a product space of the rigid motion dimensions and the diffeomorphism dimensions), the histology stacks are modelled as arising from a first order Sobolev space smoothness prior.

Is This Mine to Keep? Three-dimensional Printing Enables Active, Personalized Learning in Anatomy.

Anat Sci Educ 2018 Nov 8. Epub 2018 Nov 8.

School of Medicine (Optometry), Faculty of Health, Deakin University, Geelong, Victoria, Australia.

Understanding orbital anatomy is important for optometry students, but the learning resources available are often fragile, expensive, and accessible only during scheduled classes. Drawing on a constructivist, personalized approach to learning, this study investigated students' perceptions of an alternative learning resource: a three-dimensional (3D) printed model used in an active learning task. A human skull was three-dimensionally scanned and used to produce a 3D printed model for each student. Read More

Normal orbital anatomy plays a foundational role in stabilizing binocular eye movements. Abnormal orbital anatomy, contrariwise, destabilizes binocular eye alignment by introducing eccentric and unbalanced EOM forces. These abnormalities can be categorized into five broad etiologies: (1) orbital structural disorders; (2) globe size disorders; (3) degenerative disorders; (4) innervational disorders; and (5) trauma.

Embryologic and Fetal Development of the Human Orbit.

Ophthalmic Plast Reconstr Surg 2018 Sep/Oct;34(5):405-421

Department of Ophthalmology, University of North Carolina School of Medicine, Chapel Hill, North Carolina, U.S.A.

Purpose: To review the recent data about orbital development and sort out the controversies from the very early stages during embryonic life till final maturation of the orbit late in fetal life, and to appreciate the morphogenesis of all the definitive structures in the orbit in a methodical and timely fashion.

Methods: The authors extensively review major studies detailing every aspect of human embryologic and fetal orbital morphogenesis including the development of extraocular muscles, orbital fat, vessels, nerves, and the supportive connective tissue framework as well as bone. These interdisciplinary studies span almost a century and a half, and include some significant controversial opposing points of view which the authors hopefully sort out. Read More

Morphology and Navigational Landmarks of the Cranio-orbital Foramen in a Portuguese Population.

Ophthalmic Plast Reconstr Surg 2018 Aug 17. Epub 2018 Aug 17.

Department of Biomedicine, Unit of Anatomy, Faculty of Medicine, University of Porto, Alameda Professor Hernâni Monteiro, and.

Purpose: The cranio-orbital and accessory foramina are located in the lateral wall of the orbit and adjacent to the superior orbital fissure. In the literature, there is a lack of consistency concerning the location and morphology of these foramina in different populations. Therefore, considering its clinical importance during orbital surgeries, it was the authors' aim to determine the incidence, location, and number of cranio-orbital and accessory foramina in a Portuguese population and compare the findings with data from other studies.
