Tillstånd som åsamkar skada eller dysfunktion hos den andra hjärn- eller synnerven, vilken i allmänhet betraktas som en del av det centrala nervsystemet. Skada i optiska nervtrådar kan uppstå vid eller nära deras ursprung i näthinnan, vid synnervspapillen eller i nerven; i synnervskorsningen, synbanan eller laterala corpora geniculata. Kliniska yttringar kan bestå av nedsatt synskärpa och kontrastkänslighet, nedsatt färgseende och afferent pupillstörning.
Conditions which produce injury or dysfunction of the second cranial or optic nerve, which is generally considered a component of the central nervous system. Damage to optic nerve fibers may occur at or near their origin in the retina, at the optic disk, or in the nerve, optic chiasm, optic tract, or lateral geniculate nuclei. Clinical manifestations may include decreased visual acuity and contrast sensitivity, impaired color vision, and an afferent pupillary defect.
