Special Issue Information
Dear Colleagues,
Diabetic retinopathy (DR) remains one of the leading causes of vision impairment worldwide and represents a complex neurovascular complication of diabetes. Increasing evidence indicates that DR is not only a microvascular disease but also involves early retinal neurodegeneration, chronic inflammation, oxidative stress, metabolic dysregulation, and altered neurovascular coupling. At the molecular level, dysregulated signaling pathways related to angiogenesis, immune activation, cell death, mitochondrial dysfunction, and epigenetic regulation play critical roles in disease initiation and progression.
In recent years, interdisciplinary approaches have expanded DR research beyond traditional ophthalmology. Advances in anesthesiology and pain research have provided new insights into perioperative metabolic stress, neuroinflammation, and microcirculatory dysfunction, all of which may influence retinal vulnerability in diabetic patients. Moreover, emerging experimental platforms, including retinal organoids, stem cell–derived models, and organ-on-a-chip systems, offer powerful tools to recapitulate human retinal pathology and to investigate disease mechanisms and therapeutic responses in a translationally relevant manner.
This Special Issue aims to collect high-quality original research and reviews focusing on the molecular mechanisms underlying diabetic retinopathy. Topics of interest include, but are not limited to, inflammation and oxidative stress, neurovascular unit dysfunction, metabolic and mitochondrial pathways, pain-related and anesthetic modulation of retinal injury, organoid-based disease modeling, biomarker discovery, and novel therapeutic targets. By integrating basic, translational, and interdisciplinary research, this Special Issue seeks to advance mechanistic understanding and promote innovative strategies for the prevention and treatment of diabetic retinopathy.

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. Biomedicines 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 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.
