IThe optic pathway includes the retina, optic nerve, optic chiasm, optic radiations, and occipital cortex (see figure Higher visual pathways ).
visual field defects opticdisc
Optic disc drusen does not requiretreatment, and patients generally have good visual prognosis.
Visual Field Defects Occipital Area
Visual field testing is useful when evaluating patients complaining of visual loss (especially when the cause of visual loss is not obvious after ophthalmic examination) or patients with neurologic disorders that may affect the intracranial visual pathways.
Visual Field Defects Chiasm
The visual field defect seen in the chiasmal syndrome is typically a bitemporal hemianopsia.
Vecto Graphic Test
Vector Performance Comparison Test. Vector performance, also known as vector mode, is mainly used for cutting and single line engraving and marking.
