Nocturnal Intraocular Pressure Monitoring With a Soft Contact Lens Sensor for Glaucoma Management. [PDF]

Adv Mater
A soft contact lens sensor enables continuous, noninvasive monitoring of nocturnal intraocular pressure (IOP) under closed‐eye sleep conditions. By integrating a highly compliant inductive–capacitive circuit onto a commercial lens, the device achieves record sensitivity and stable performance.

Comparison of Dynamic Contour Tonometry and Goldmann Applanation Tonometry

Journal of the Korean Ophthalmological Society, 2009
Purpose: To compare dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) and investigate the influence of central corneal thickness (CCT) onintraocular pressure. Methods: In a prospective study of 165 eyes with glaucoma (135 eyes), glaucoma suspect (14 eyes), and ocular hypertension (16 eyes), intraocularpressure was measured with ...

Flexible wearable electronics for cardiovascular monitoring from surface signals to deep physiological insights

FlexMat, EarlyView.
This review organizes flexible wearable electronics for cardiovascular monitoring into four interconnected information layers: surface electrophysiology, hemodynamic sensing, vascular imaging, and biofluid biomarker analysis. This framework clarifies how electrical rhythm, vascular loading, structural and flow‐related features, and biochemical states ...

Longitudinal changes in bleb morphology following the PAUL Glaucoma Implant visualized using ultrasonography

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate bleb morphology longitudinally using sonography following glaucoma drainage device (GDD) surgery. Methods Prospective observational cohort study conducted from January 2022 to March 2024, with follow‐up up to 12 months postoperatively. Bleb morphology, including superior and inferior bleb height, transverse and longitudinal

Australian and New Zealand Glaucoma Society (ANZGS) Consensus on Interventional Glaucoma

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Traditional reactive ‘wait and see’ approaches in glaucoma management often result in unacceptable rates of permanent vision loss. This consensus defines a proactive ‘interventional glaucoma’ framework tailored for the Australian and New Zealand healthcare context. Methods A modified Delphi consensus process was utilised, consisting
