We also describe new technologies for visualizing the extracranial vessels in the diagnosis of giant cell arteritis (GCA). Recent findings Newer OCT modalities are expanding the evaluation of the optic disc, and are being applied to a number of neurologic conditions such as demyelinating and neurodegenerative disease. Swept-source OCT and enhanced-depth imaging OCT are refining the fine-grained analysis of the optic nerve head in the diagnosis of papilledema and optic nerve drusen. OCT-angiography is opening up new avenues to the study of the vasculature of the optic nerve head and its disorders, including ischemic optic neuropathy. Newer technologies in the diagnosis of GCA include vascular ultrasound, magnetic resonance imaging (MRI) of the extracranial vasculature and PET imaging of the large vessels. Summary OCT and several of its derivations are advancing diagnosis, and in some cases prognostication, in a variety of inflammatory, ischemic and compressive optic neuropathies. These technologies hold potential in the laboratory as well, yielding insights into the mechanisms of a variety of neurological conditions. In addition, further developments in MRI and ultrasonography techniques are shaping the approach to the diagnosis of GCA. Copyright © 2018 Wolters Kluwer Health, Inc. All rights reserved.
