Advances in Neuro-Ophthalmic Imaging
Recent years have brought a rapid evolution of diagnostic imaging studies in neuro-ophthalmic practice. Optical coherence tomography (OCT) and several of its derivations (swept-source OCT, enhanced-depth imaging OCT, and OCT-angiography) 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 magnetic resonance imaging and ultrasonography techniques are shaping the approach to the diagnosis of giant cell arteritis.
