What is it?
Optic neuritis is the inflammation of the optic nerve.It is the nerve that carries visual information from your eye to your brain. ON can flare up suddenly from an infection or nerve disease. The inflammation usually causes temporary vision loss that typically happens in only one eye. Those with ON sometimes experience pain. As you recover and the inflammation goes away, your vision will likely return.
What are the symptoms?
The three most common symptoms of ON are: * vision loss in one eye, which can vary from mild to severe and lasts for 7 to 10 days * periocular pain, or pain around your eye that’s often worsened by eye movements * dyschromatopsia, or the inability to see colors correctly Other symptoms can include: * photopsia, seeing flashing lights (off to the side) in one or both eyes * changes in the way the pupil reacts to bright light * Uhthoff’s phenomenon (or Uhthoff’s sign), when eye vision worsens with an increase in body temperature
- Use dark glasses to protect the eye.
- Over-the-counter eye drops, such as artificial tears, may help the eye feel better.
Avoid bright lights
Things to watch out for
Immediately go to emergency or call 000. Medications can help speed recovery. Complete (or nearly complete) vision returns within two to three months, but it may take up to 12 months to achieve the vision recovery.
