Optical Coherence Tomography Imaging: Advances in Ophthalmology

Dear Colleagues,

The advent of optical coherence tomography (OCT) has arisen in an era in which the in vivo, cross-sectional imaging of both the retina and choroid is possible. Infra-red rays of light are used to image the chorioretinal layers with an image resolution reaching 10-15 microns. During the last 3 decades, OCT technology has undergone several improvements, such as spectral domain OCT (SD-OCT), swept source OCT (SS-OCT), enhanced depth imaging (EDI-OCT), wide field OCT, intraoperative OCT, OCT angiography (OCTA), and adaptive optics OCT. These enhancements help in both the qualitative and quantitative analysis of chorioretinal parameters in pathologies such as macular edema, neurosensory detachment, retinoschisis, macular hole, epiretinal membrane, and choroidal tumors. An added advantage is the role of OCT in the evaluation of optic disc disorders, including optic neuritis and glaucoma, by the quantitative analysis of the retinal nerve fiber layer. Moreover, OCT being non-invasive provides an opportunity for serial imaging during follow-up visits. Overall, OCT imaging provides tissue details, closely mimicking the histopathology, and is an invaluable asset in the armamentarium of retina physicians.

This issue welcomes both original (prospective and retrospective) and review articles, and will focus on the applications of OCT in various chorioretinal disorders.

Topics of interest will include, but are not limited to, the following:

• Advances in OCT;
• OCT angiography;
• OCT applications in various retinal and choroidal disorders;
• OCT biomarkers;
• Age-related macular degeneration;
• Diabetic retinopathy;
• Central serous chorioretinopathy;
• Uveitis;
• Inherited retinal diseases;
• Neurological diseases.

Manuscript Submission Information

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 250 words) can be sent to the Editorial Office for assessment.

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. Journal of Clinical Medicine 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.
