Advances in Glaucoma Surgery

Delhi Journal of Ophthalmology, 2016
Currently popular glaucoma filtration surgeries which include trabeculectomy and glaucoma drainage devices have their share of vision-threatening complications. Lately less invasive and safer devices have been developed to be used alone or in conjunction with cataract surgery for lowering the intraocular pressure. These microscopic implants utilize the

Ion‐Pair‐Tuned Ionogels for Broad‐Range Linear Pressure Sensing

Advanced Science, EarlyView.
Ionogels engineered through ion‐pair tuning extend the linear sensing range of capacitive pressure sensors. By balancing ionic mobility and polarizability within the polymer matrix, this approach mitigates dielectric saturation and maintains a stable pressure response across a broad operating range.

A Viscous DES‐AAV‐Foxo1 Delivery System With High Transfection Efficiency for the Treatment of Corneal Endothelial Dysfunction by Restoring Mitochondria‐ER Contacts

Advanced Science, EarlyView.
High glucose triggers corneal endothelial dysfunction by impairing FOXO1‐mediated ITPR1 transcription, leading to disrupted mitochondria‐associated membrane (MAM) integrity and defective ER‐to‐mitochondria Ca2+ transfer. This study develops an innovative viscous DES‐AAV‐Foxo1 delivery system with enhanced transfection efficiency. This non‐invasive gene

Retinal Vessel Segmentation: A Comprehensive Review From Classical Methods to Deep Learning Advances (1982–2025)

Advanced Intelligent Systems, EarlyView.
Four decades of retinal vessel segmentation research (1982–2025) are synthesized, spanning classical image processing, machine learning, and deep learning paradigms. A meta‐analysis of 428 studies establishes a unified taxonomy and highlights performance trends, generalization capabilities, and clinical relevance.

Plasma endothelin-1 and endothelin-A receptor concentrations in patients with primary open-angle glaucoma

Biotechnology & Biotechnological Equipment, 2017
Endothelin-1 (ET-1) is a potent vasoconstrictor and is considered to have a key role in the regulation of ocular perfusion and glaucoma pathogenesis. High ET-1 and ETA-receptor levels are reported in patients with primary open-angle glaucoma (POAG).
