and rarely vision loss secondary to trauma to the optic nerve or central retinal artery. There is significant risk of complication related to the placement of shunts for IIH, including shunt ...

AIM A study was designed to investigate whether measurements of the optic nerve diameter (OND) and cross sectional area (ONCSA), as measured by B-scan ultrasonography, are altered in glaucoma. The ...

At ARVO 2025, in Salt Lake City, Utah, Danielle Gauthier talked about her poster on autosomal dominant Alzheimer disease in relation to optic nerve head drusen. At ARVO 2025, in Salt Lake City, Utah, ...

In adult humans, the optic nerve displays limited regenerative capacity, typical of neurons of the CNS. In efforts to address this issue, a number of recent advances have been made in the ...

AIM--To present a new non-invasive method of performing a high definition topography of perfused vessels of the retina and the optic nerve head with simultaneous evaluation of blood flow. METHOD--By a ...

The optic nerve sends messages from the eyes to the brain. When light enters the eye, it hits the retina, which contains rods and cones. These are photoreceptors that translate signals from light ...

There is now also widespread availability of spiral (helical) volume computed tomography (CT) where high definition planes or surfaces can be reconstructed to produce detailed depiction of bone, ...

Abstract: A novel accurate and fast optic disc (OD) detection method is proposed by using vessel distribution and directional characteristics. A feature combining three vessel distribution ...

Background: Although intracranial pressure (ICP) monitoring is the gold standard method for measuring intracranial pressure after traumatic brain injury, optic nerve sheath diameter (ONSD) measurement ...

Augmented blood flow velocity is recognized to promote vascular remodeling. Importantly, increased vascular sympathetic nerve fiber density and innervation in early life plays a key role in the ...

However, these tests can be invasive, associated with radiation exposure, contraindicated, or not readily available. Ultrasonography measurement of the optic nerve sheath diameter (ONSD) is proposed ...
