Retinal regions shape human and murine Müller cell proteome profile and functionality

Glia, Volume 71, Issue 2, Page 391-414, February 2023., 2023
Main Points We defined Müller cells heterogeneity in the macular and peripheral human retina. Signaling pathways shaping this glial heterogeneity include proteins important for interaction with vesicular secretion, extracellular matrix and cell adhesion.

Volume‐rendered optical coherence tomography angiography during ocular interventions: Advocating for noninvasive intraoperative retinal perfusion monitoring

Journal of Biophotonics, Volume 15, Issue 12, December 2022., 2022
In ophthalmic surgery, intraoperative retinal perfusion assessment/monitoring has been suggested for numerous indications, typically using fluorescence angiography. However, applicability is limited given the difficult arrangement, associated risks and the lack of automated/objective perfusion quantification.

Theranostic‐guided corneal cross‐linking: Preclinical evidence on a new treatment paradigm for keratoconus

Journal of Biophotonics, Volume 15, Issue 12, December 2022., 2022
Theranostics is an emerging therapeutic paradigm of personalized and precision medicine that performs therapy guided by molecular diagnostic imaging. The technology was implemented in a UV‐A medical device and showed to efficiently drive the operator in performing personalized riboflavin/UV‐A corneal cross‐linking for treatment of corneal disorders ...

Sclera Segmentation and Recognition for Spectacle Dataset [PDF]

ITM Web of Conferences
Sclera, a connective tissue enveloping the eye, emerges as a novel biometric recognition method for human identification. The composition of blood vessels in the sclera proves ideal for biometric use—visible with ease, stable over time, and unique to ...

Mass spectrometry in ocular drug research

Mass Spectrometry Reviews, EarlyView., 2023
Abstract Mass spectrometry (MS) has been proven as an excellent tool in ocular drug research allowing analyzes from small samples and low concentrations. This review begins with a short introduction to eye physiology and ocular pharmacokinetics and the relevance of advancing ophthalmic treatments.

Needle detection and localisation for robot‐assisted subretinal injection using deep learning

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Subretinal injection is a complicated task for retinal surgeons to operate manually. In this paper we demonstrate a robust framework for needle detection and localisation in robot‐assisted subretinal injection using microscope‐integrated Optical Coherence Tomography with deep learning.

Stress induced aging in mouse eye

Aging Cell, Volume 21, Issue 12, December 2022., 2022
Skowronska‐Krawczyk and colleagues describe the transcriptional and epigenetic changes happening in aging retina. They also show that upon stress such as intraocular pressure elevation in the eye, retinal tissue undergoes epigenetic and transcriptional changes similar to natural aging.

The Use of Tutoplast as an Adjunct in Scleral Buckle Procedure in Patients with Extremely Thin Sclera

Journal of Ophthalmic & Vision Research, 2021
Extremely thin sclera often necessitates abortion of scleral buckle procedures. In patients in whom a scleral buckle is desired, previous techniques have included the use of cyanoacrylate glue and continuing with surgery or placing donor tissue over the ...
