Thank you for your question. Optic nerve swelling may be reversed by few nutrients such as lutein, l-lysine, few vitamins & enzymes, and fish oil and may be a good help in preserving the vision. However, I think your treating ophthalmologist is the best judge who can see the extent of disease and provide a proper insight of the situation. Hope this helps.

Hi ingrid.I have swollen optic disks/nerves as well . It is called Papillodema. There are a few reasons for it, but the most common one is IIH/PTC., which I also have. If your lumber puncture ,opening pressure was 31 then I would say you are probabley looking at this for a diagnoses.
Try not to worry to much and I will help in any way I can. I know a lot about this illness and would be glad to answer any questions. Cath278.
