If a pt presents with a VF defect c/w an arcuate fiber lesion, what condition should you consider first? Why does glaucoma preferentially damage arcuate fibers?

Nov 29, 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.

The diagram on the left illustrates the basic organization of the primary visual pathway and indicates the location of various lesions. The right panels illustrate the visual field deficits associated with each lesion.

May 19, 2020 · This printable cheat sheet breaks down each stage of the visual pathway with diagrams, definitions, and space for your own notes. It's perfect for refreshing your memory on how pathology in the primary visual pathway can affect vision function or even for explaining visual field defects to patients!

Sep 14, 2022 · Knowing the patterns of visual deficits can help to diagnose and manage patients. Learn components of the visual pathway as well as the types of defects that may result from a lesion along the pathway through this article and the corresponding illustrated cheat sheet.

Superior visual field information is projected onto the inferior retina, and the inferior field information onto the superior retina The neurons that originate in the superior or inferior retina maintain their topographic positions throughout the visual pathway until …

Feb 5, 2024 · Visual field defects can arise from multiple different pathologies throughout the visual pathway, and the type of defect can provide important links about the underlying pathology.

Jun 27, 2017 · Each eye has a left and right visual field. In a right upper homonymous quadrantanopia the right visual field of both the right eye and left eye is lost. The lesion is of the left temporal radiation (remember that Temporal produces a Top quadrantanopia).

We evaluated the following: best-corrected visual acuity, visual field mean deviation (MD), the amplitude (A) of Pattern Electroretinogram (PERG), the implicit time (IT) and A of Visual...

Diagram of visual field defects (scotoma, anopia, hemianopia, quadrantanopia) and their anatomical correlations in the visual pathway. Neuro-ophthalmology aid.
