Cavernous malformations of the optic pathway are rare vascular anomalies defined by clusters of dilated, thin‐walled capillaries that may develop along the optic nerve, chiasm, or tract. These lesions ...

A Scientific Online Poster presented during the 2023 ARRS Annual Meeting, held April 16–20 on the island of Oahu, explained how the novel technique of three-dimensional (3D) slice-to-volume (SVR) MRI ...

Left: Study design. We analyzed dMRI data acquired from 17 patients with glaucoma and 30 healthy controls, and then compared the data with and without denoising. Right: Comparison between data with ...

A research team has established an innovative intracranial pre-olivary pretectal nucleus (OPN) optic tract injury model (pre-OPN OTI), shedding light on crucial mechanisms of functional axonal ...

Band optic atrophy is described as a horizontal band of optic disc pallor, often associated with a contralateral optic tract lesion and bilateral hemianopic visual field defects. Relative afferent ...

For decades, MRI (magnetic resonance imaging) has been a powerful way to see inside the human brain. A specialized form, diffusion-weighted MRI (dMRI), can measure tissue properties of fiber pathways ...

Biomedical scientists reports a drug -- an estrogen receptor ligand called indazole chloride (IndCl) -- has the potential to improve vision in patients with multiple sclerosis, or MS. The study was ...

The keen practitioner can gain helpful information simply by assessing pupillary responses. The pupils will offer substantial insight into one’s ocular health and the state of the visual pathways ...

An award-winning presentation during the 2023 ARRS Annual Meeting explained how the novel technique of three-dimensional (3D) slice-to-volume (SVR) MRI allows for precise delineation and measurement ...
