There seems no connection between optic neuritis and eye floaters. As to optic neuritis, it refers to the inflammation of optic nerves which connect eyes with brain. These nerves would help transfer information from retina to the brain so that we can get images saw by eyes. Optic neuritis would lead to vision dimishing or even loss. Although according to some studies, it can heal up by itself in one or two weeks, I still recommend patients to see doctors if they might have optic neuritis. Given proper treatment, it could recover faster so that patients will sufer less from it. As to eye floaters, it refers to small floating spots in vision, due to various problems, like aging, retinal detachment or eye injuries. Normally speaking, eye floaters won't imapct vision seriously.
