Background
Evaluation of the optic disc allows for an opportunity to assess the CNS directly and represents an easily overlooked segment of anatomy with important implications for both clinicians and radiologists. We intend to present an up-to-date case-based imaging review of adult and pediatric pathologies of the optic disc from a busy academic referral center. Our exhibit will include a pictorial and image-based review of normal optic disc, optic nerve, and relevant orbital anatomy; a review of modalities for effective imaging of the optic disc; congenital abnormalities of the optic disc and associated relevant CNS abnormalities; acquired abnormalities of the optic disc (degenerative conditions, papilledema, etc.) with associated CNS disorders.

Educational Goals / Teaching Points
Educational goals and teaching points include discussion of long-term implications that optic disc abnormalities have on visual function; CNS abnormalities with associated congenital and acquired optic disc abnormalities; and the role of imaging as an important adjunct to ophthalmoscopic examination in the management of patients with optic disc abnormalities. Participants will develop a fundamental understanding of the spectrum of optic disc abnormalities and the mechanism of their association to neuroradiology.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Key anatomic considerations for this topic include the orbit, the globe, the components of the optic nerve system, and their respective constituent components. The primary imaging techniques relevant to this topic are CT and MRI. Correlative examples of available ophthalmoscopic abnormalities will be included where appropriate. This topic will include discussion of a range of pathophysiology including ischemic processes, inflammatory disease, neoplastic processes, and proliferative dyscrasias. Discussion of both adult and pediatric processes will be included.

Conclusion
An understanding of the spectrum of optic disc abnormalities and their associated CNS diseases, in both adult and pediatric patient populations, is a key component of neuroradiology education. It is our hope that this exhibit will provide an easily digestible pictorial review of this topic that can serve as a primer for radiologists-in-training and potentially as a review for practicing radiologists.
