Final answer:
A Nerve Fiber Bundle Scotoma refers to a blind spot within the visual field caused by damage to a bundle of nerve fibers, called the optic nerve when in the PNS, and optic tract when in the CNS.
Step-by-step explanation:
Nerve Fiber Bundle Scotoma refers to a localized area of vision loss (blind spot) within the visual field due to a bundle of nerve fibers, which can be affected due to various pathologies. In the context of the visual system, this phenomenon is typically associated with the optic pathways. The optic nerve, also known as the second cranial nerve, is responsible for transmitting visual information from the retina to the brain. When these axons, or nerve fibers, are located within the peripheral nervous system (PNS), they are termed 'optic nerve'. However, as they pass the optic chiasm and are located within the central nervous system (CNS), they are named 'optic tract’. A Scotoma caused by a lesion in these fibers could be due to damage anywhere along the optic nerve or tract.
