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

Intraocular Pressure Study in Ex Vivo Pig Eyes by the Laser-Induced Cavitation Technique: Toward a Non-Contact Intraocular Pressure Sensor

Applied Sciences, 2020
Traditional applanation tonometry techniques lack the necessary accuracy and reliability for measuring the intraocular pressure (IOP), and there is still a need for a reliable technique for in vivo diagnosis.

An Intraocular Pressure Measurement Technique Based on Acoustic Radiation Force Using an Ultrasound Transducer: A Feasibility Study

Sensors, 2021
High intraocular pressure (IOP) is one of the major risk factors for glaucoma, and thus accurate IOP measurements should be performed to diagnose and treat glaucoma early. In this study, a novel technique for measuring the IOP based on acoustic radiation

Childhood ocular safety after postnatal exposure to topical dexamethasone during retinopathy of prematurity screening

Acta Ophthalmologica, EarlyView.
Abstract Purpose Dexamethasone eye drops are being introduced off‐label to prevent progression of severe retinopathy of prematurity (ROP). We evaluated ophthalmologic outcomes in early childhood after postnatal topical dexamethasone exposure in pre‐term infants at a standardized follow‐up examination.

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

Ocular Manifestations of Metabolic Syndrome: A Systemic Vascular Phenotype

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Context Metabolic syndrome (MetS) is defined by central obesity, insulin resistance, hypertension and dyslipidemia. MetS affects over one‐third of US adults. Beyond its cardiovascular burden, MetS has clinically relevant associations with ocular health and may contribute to a systemic vascular and neuro‐metabolic phenotype involving the retina,

Equine eyelid reconstruction by semi‐circular skin flap blepharoplasty

Equine Veterinary Education, EarlyView.
Summary Reconstructive surgeries of the equine eyelid carry significant challenges for the equine surgeon, due to the poorly mobile and tightly adhered facial skin in this species. Preservation of lid function is an essential surgical consideration in order to maintain protection of the globe and cornea and to provide ocular comfort to the case ...

Analysis of the circadian rhythm of intraocular pressure in stable and progressive forms of primary open-angle glaucoma

Российский офтальмологический журнал, 2019
Purpose. To analyze the daily dynamics and the parameters of intraocular pressure circadian rhythm (IOP CR) in patients with primary open-angle glaucoma (POAG) (stable and progressive forms) and determine chronobiological regularities of glaucoma ...
