Retinal Ganglion Cell Responses to Low-frequency Focused Ultrasound Stimulation

, 2017
PURPOSE: Acoustic retinal prosthesis has been put forward using high-frequency US with non-invasive and high-resolution advantages. But its application is limited by the difficulties in fabrication, energy consumption and acoustic attenuation.

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

Acta Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

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 ...

Oral nicotinamide provides robust, dose-dependent structural and metabolic neuroprotection of retinal ganglion cells in experimental glaucoma

Acta Neuropathologica Communications
A compromised capacity to maintain NAD pools is recognized as a key underlying pathophysiological feature of neurodegenerative diseases. NAD acts as a substrate in major cell functions including mitochondrial homeostasis, cell signalling, axonal ...

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.

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

Gene expression analysis during retinal ganglion cell development

, 2015
Retinal ganglion cells are the final output neurons that gather electrical signals from light-sensing cells and relay this information to discrete locations in the brain. The loss of ganglion cells due to cell death is an irreversible process in glaucoma.
