Optic Neuritis: Symptoms, Complaints, Signs

The following symptoms and complaints may indicate optic neuritis (optic neuritis):

  • Eye movement pain (eye movement pain; bulbar movement pain; bulbar pain (pressure, movement); 92% of patients).
  • Visual loss (visual deterioration) (onset: within hours to days) [visual impression:
    • Blurred vision to complete loss of visual acuity (vision loss).
    • Disturbed color perception (colors are perceived as dirty and pale)]

Other notes

  • In 99.6% of cases, the disease occurs unilaterally.
  • Eye movement pain is absent in 8% of patients because the focus of inflammation is intracranial (“localized within the skull“), and thus outside the optic nerve, which is mobile.
  • Improvement in 95% of cases; about 60% of patients achieve normal vision after 2 months.
  • Typical optic neuritis is defined as follows:
    • Age 18-50 years
    • Appearance unilateral
    • Eye movement pain
    • Improvement of the complaints
    • No evidence of systemic disease other than multiple sclerosis (MS).
  • Uhthoff phenomenon: a transient deterioration in visual acuity (visual acuity) occurring after physical exertion-induced increase in temperature. The phenomenon is specific but occurs in only about half of patients with multiple sclerosis. Typical triggers are sports, hot showers and bathing.
