29 lis 2020 · Understanding the anatomy of the optic nerve and visual pathways is key to appreciating how various focal lesions of the brain cause characteristic visual field defects.
Learn about the visual field, the portion of space in which objects are visible during steady fixation, and how it is measured by perimetry. Find out the causes and types of visual field defects, such as scotomas, hemianopsia, and tunnel vision, and their association with glaucoma.
30 sty 2024 · Visual field defects (VFD) are common in neurological disorders and adversely impact patient quality of life and disease morbidity [1]. The pattern of VFD aids precise anatomical localization of the lesion due to the retinotopic arrangement of the afferent visual pathway [2, 3].
Visual field defects in nonarteritic anterior ischemic optic neuropathy (NA-AION) include altitudinal field defect (classically occurring in the inferior hemifield), central scotoma, arcuate scotoma, and quadrantic defects.
15 cze 2020 · Learn how to interpret visual field (VF) tests systematically and identify common defects, artifacts and progression. This article provides a framework, resources and examples for ophthalmologists and residents.
Learn about the causes, locations, and types of visual field defects caused by mass effect on the visual pathway. Find out how to diagnose and treat compressive lesions affecting the orbit, optic nerve, chiasm, and retrochiasmal structures.
