Visual acuity was generally normal in spite of gross visual field constriction. Conclusion: We believe that VGB should be used with great caution where there is pre-existing visual pathway damage.

New research reveals how early-life blurry, low-color vision may help shape the brain’s visual pathways into specialized ...

Incoming information from the retina is channeled into two pathways in the brain's visual system: one that's responsible for ...

Hubel and Wiesel found that neurons in the visual cortex show orientation selectivity. Jimmierock Hubel and Wiesel initially demonstrated that, further along the visual pathway in the cortex, cells in ...

Aim: To examine whether visual restitution training (VRT) is able to change absolute homonymous field defect, assessed with fundus controlled microperimetry, in patients with hemianopia. Methods: 17 ...

Chiasmal visual field defects are usually categorised as extrinsic because of mechanical compression from adjacent structures, although lesions involving the substance of the chiasm itself also ...

AIMS To simulate the central binocular visual field using results from merged left and right monocular Humphrey fields. To assess the agreement between the simulation and the binocular Humphrey ...

Methods: Twenty nine patients with homonymous visual field defects (HVFD) without neglect practised VS paradigms in 20 daily sessions over one month. Search fields comprising randomly positioned ...

Introduction Glaucoma, a neurodegenerative disorder affecting the entire visual pathway, currently impacts over 79 million individuals globally, of whom more than 11 million will progress to bilateral ...

Neuroscientists want to understand how individual neurons encode information that allows us to distinguish objects, like ...
