More often neuritis an optic nerve it is combined with a multiple sclerosis - slowly progressing disease of the nervous system shown just this most demyeliniation. The inflammation of an optic nerve is frequent is a debut of a multiple sclerosis or precedes development of a multiple sclerosis for some years. Sometimes the reason of development neuritis an optic nerve remains to the unknown person.

The majority of patients with neuritis of an optic nerve test sharp deterioration of sight in a combination to a pain arising at movement by a sick eye. This disease is usually shown on one eye and can periodically give relapses, as for example often happens at a combination to a multiple sclerosis.

Does anyone know where I can find an image online of a Mary Quant sixties dress?

I am doing an Art project about "Movement" and right now am doing about optical art. I have heard that Mary Quant used op art in her clothes and I thought I could do a page on her designs, however, I can't find any images of her actual designs. :
