Hormonal replacement therapy in postmenopausal women ≥50 years is associated with the incidence of glaucoma: Evidence from 6576 females in Finland

Acta Ophthalmologica, EarlyView.
Abstract Purpose Hormonal replacement therapy (HRT) in postmenopausal women appears to affect glaucoma risk, but findings are inconsistent. We aimed to explore whether the use of postmenopausal HRT plays a role in glaucoma development in Finland. Methods The main outcome variable was glaucoma incidence measured by initiation of special reimbursement ...

The effect of rhegmatogenous retinal detachment on retinal oxygenation

Acta Ophthalmologica, EarlyView.
Abstract Purpose Little is known about the effects of retinal detachment on oxygen extraction from retinal vessels. The role of oxygen supply from the retinal vessels in a detached area has not previously been investigated in vivo in humans. Retinal oximetry is a non‐invasive measurement of retinal oxygen saturation.

Intraocular pressure control efficacy and safety of HA-Mg glaucoma drainage plate implantation in the anterior chamber of rabbit eyes

Journal of Materials Science: Materials in Medicine
The current clinical application of glaucoma drainage devices is made of non-degradable materials. These non-degradable drainage devices often trigger inflammatory responses and scar proliferation, possibly leading to surgical failure.

A New Adjustable Glaucoma Drainage Device

Investigative Opthalmology & Visual Science, 2014
This work is focused on the testing of a new experimental noninvasively adjustable glaucoma drainage device (AGDD) that allows for the control of its outflow resistance to modulate intraocular pressure (IOP) in a customized fashion.Six AGDDs were directly connected to a pressure transducer and a perfusion system continuously delivering saline solution ...

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

A model for designing intraocular pressure-regulating glaucoma implants.

PLoS ONE, 2022
Glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for vision. The key risk factor for the development and progression of this disease is increased intraocular pressure (IOP).

Minimally Invasive Parylene Dual-Valved Flow Drainage Shunt for Glaucoma Implant [PDF]

, 2009
A parylene-enabled microvalved shunt implant for glaucoma drainage is presented in this paper. Enabled by the dual-checkvalve operation, this device can physically drain the extra intraocular fluid and regulate the intraocular pressure (IOP) within the ...

Reduced order modelling of air‐puff test for corneal material characterisation

Journal of Microscopy, EarlyView.
Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.
