What is optic neuritis?
Optic neuritis is inflammation of the optic nerve, the structure that
connects the eye to the brain. The optic nerve consists of nerve tracts (axons)
that originate in the retina of each eye. The optic nerve carries visual
information from the retina to the nerve cells in the brain stem, where the
information is relayed to the area of the brain that recognizes vision (the
occipital cortex).
Optic neuritis can occur in children or adults and may involve either one or
both optic nerves. Optic neuritis typically affects young adults ranging from
18-45 years of age, with a mean age of 30-35 years. There is a strong female

I was then started on IV antibiotics for 28 days. Published: August 27 ::
