Special Issue Information
Dear Colleagues,
The eye, although seemingly easy to access, is a complex and dynamic organ that presents unique challenges for drug delivery. With formidable tissue barriers and a rich perfusion of blood vessels, the eye significantly restricts the entry of foreign substances; meanwhile, due to its vulnerable nature, the toxicity and irritation potential of conventionally used formulations and excipients are often heightened. As such, ocular drug delivery is essentially a compromise between safety and efficacy.
In recent years, “nanomedicine” has been extensively investigated due to its proposed advantages of sustained and targeted drug delivery, reduced adverse effects, and enhanced bioavailability of hydrophobic and hydrophilic drugs, macromolecules, proteins, and peptides as well as biological vectors, including genes and antibodies. Thus, nanotechnology may facilitate the delivery of ocular therapeutics in clinically relevant concentrations to the anterior, and possibly even posterior, ocular tissues.
This Special Issue highlights new and emerging research in nanomedicine for both the topical and intraocular administration of ocular therapeutics and its application in the treatment and management of ocular pathologies.

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. Pharmaceutics 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.
