The optic nerve is considered an extension of the central nervous system and essential for the sensory function of vision. It contains the axons of ganglion cells from the retina. Approximately how many axons are bundled in the optic nerve of each eye?
Localize the lesion: What structure is possibly involved in a patient with dyschromatopsia (color vision deficiency)?
A 32-year-old woman presents to the ER because of loss of vision and pain behind the eyes when she looks to the right. Her visual acuity was found to be 20/40 in the right eye and 20/20 in the left eye. She cannot see color vision well. What do you expect to find in a pupillary exam in this patient if you were to see the patient in the ER that would help make the diagnosis of optic neuritis before any neuroimaging is initiated?
