The visual system is the physiological basis of visual perception (the ability to detect and process light). The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
19 gru 2022 · The visual system consists of 2 primary parallel pathways: optic and pupillary reflex pathways. [2] [3] Optic Pathway. The optic pathway begins in the retina, a complex structure of 10 layers, each serving a distinct function.
28 sie 2023 · Summary. This chapter examines the visual system: its development, its anatomy, and its distribution through the brain. It describes the anatomy of the eye, the layered components of the retina and the central components of the visual pathways. The chapter discusses clinical problems regarding pupillary light reflexes and visual field defects ...
1 kwi 2017 · Abstract and Figures. Vision is the primary sense in humans. There are approximately one million axons in the optic nerve, constituting almost 40% of the total number of axons in all cranial ...
Explain how the optical system of the eye creates an image on the retina. Describe phototransduction (i.e., how light activates photoreceptors) and explain the process of light and dark adaptation. Compare and contrast the functions and locations of rods and cones.
Detailed knowledge of the anatomy of the visual system, in combination with skilled examination, allows precise localization of neuropathological processes. Moreover, these principles guide effective diagnosis and management of neuro-ophthalmic disorders.
