Update on Optical Coherence Tomography Angiography Imaging in Optic Neuropathies

Dear Colleagues,

In recent years, the structural analyses of the retina and retinal nerve fiber layer (RNFL) using optical coherence tomography (OCT ) have been proven to be an excellent tool for detecting and monitoring axonal loss and neurodegeneration in patients with different diseases of the retina and optic nerve. Moreover, optical coherence tomography angiography (OCT-A) provides non-invasive and reliable data which allows for measurements of microvascular changes in the retina and choroid as well as RNFL defects. OCT-A facilitates en-face visualization of the retinal circulation into the superficial and deep vascular networks supplying the various retinal layers. As a new diagnostic tool, OCT-A has been widely used in retinal vascular diseases; however, publications on the utility of OCCT-A in optic neuropathies are scarce.

This Special Issue aims to evaluate OCT-A in optic neuropathies of different origin, including traumatic, ischemic (arteritic and non-arteritic), inherited (Leber hereditary optic neuropathy, dominant optic neuropathy), inflammatory, demyelinated (multiple sclerosis, neuromyelitis optica), compressive (optic nerve tumors) and toxic. Additionally, reports on using OCT-A in congenital optic disc anomalies, as optic disc drusen and optic hypoplasia, are welcome. Moreover, studies on retinal microvasculature in optic disc edema and optic disc atrophy are of our interest. The results of the studies on OCT-A imaging in optic neuropathies will provide a background for future more detailed differentiation between optic neuropathies of different origin.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diagnostics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
