B-scan ultrasound can effectively differentiate between peripapillary hyperreflective ovoid mass-like structures and optic ...

This latter observation is of importance because transorbital B-scan ultrasonography looking along the optic nerve longitudinally relies on a poorer lateral resolution of the ultrasound pulse, rather ...

17 Also, a significantly smaller OND was found in 49 pts with glaucoma compared to 90 controls when measured by the B-scan ultrasonography technique.14 This smaller size could be attributed to optic ...

The remainder of his funduscopic examination was normal. There were no visual field defects. Colour vision was assessed with Ishihara plates and was normal. He then underwent B-scan ultrasonography to ...

Optic neuritis (ON) is an inflammation that damages your optic nerve. It can cause vision loss and pain when you move your eyes. As the inflammation goes away, your symptoms usually get better.

In contrast, demyelination of the optic nerve can affect eyesight. How fast these symptoms can develop can depend on the cause of demyelination. In some chronic conditions, like multiple sclerosis ...

This important study provides new evidence on the role of norepinephrine (NE) release in the hippocampus in response to environmental transitions (event boundaries), providing a potential link between ...
