Date of Activity Release: Aug. 1, 2017
Date of Activity Expiration: Aug. 1, 2020

Target Audience:
Intended for neuroradiologists and neuroradiology trainees with varying degrees of experience.

Learning Objective:
The reader will understand the embryology of the orbit and how this relates to the developmental variations that occur.

Abstract
The eye is truly an extension of the brain and the end organ of the visual pathway. An understanding of how the eye develops and then how the extraocular structures arise allows not only a better understanding of their anatomy but also provides insight into the congenital problems that may arise. The development of the orbit is the result of complex multifactorial molecular pathways that are just beginning to be better understood, and this understanding is primarily based on animal models. This review takes the reader step by step through this embryology, with numerous figures to help the reader better understand the text. A section is also included that mentions some of the more common gene-related orbital abnormalities.

Commercial Support
