Special Issue Information

Dear Colleagues,

The oxidative stress plays a major role in the pathogenesis of multiple ocular diseases, either in the anterior or in the posterior segment of the eye, and is at the base of a vicious cycle in which oxidative stress burden progressively accumulates. The impairment of the endogenous anti-oxidant defenses with aging also contributes to dysfunction and oxidative stress burden in such diseases. In this context, natural compounds, and nanotechnological and molecular approaches targeting the oxidative stress or prompting the rescue of anti-oxidant defenses represent challenging strategies for the development of therapies to delay/limit the progression of multiple diseases.

In this Special Issue we invite researchers to provide original research articles, clinical reports, and review articles that relate to oxidative stress and corneal (i.e., keratoconus), lens (i.e., cataract) and retinal (i.e., age-related macular degeneration) diseases. Additionally, studies on anti-oxidant therapeutic strategies may be submitted for evaluation.

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 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. Antioxidants is an international peer-reviewed open access monthly 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 2900 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.

Molecular oxygen is a primary oxidant that is involved in the formation of active oxygen species and in the oxidation of lipids and proteins. Thus, controlling oxygen partial pressure (concentration) in the human organism, tissues, and organs can be the first step in protecting them against oxidative stress. However, it is not an easy task because oxygen is necessary for ATP synthesis by mitochondria and in many biochemical reactions taking place in all cells in the human body. Moreover, the blood circulatory system delivers oxygen to all parts of the body. The eye lens seems to be the only organ that is protected from the oxidative stress through the regulation of oxygen partial pressure. The basic mechanism that developed during evolution to protect the eye lens against oxidative damage is based on the maintenance of a very low concentration of oxygen within the lens. This antioxidant mechanism is supported by the resistance of both the lipid components of the lens membrane and cytosolic proteins to oxidation. Any disturbance, continuous or acute, in the working of this mechanism increases the oxygen concentration, in effect causing cataract development. Here, we describe the biophysical basis of the mechanism and its correlation with lens transparency. Full article
