Vision problems

Is there anybody out there who has pixilated vision like my daughter? She started with Optic Neuritis in December 2014, went virtually blind when ADEM symptoms were at their worse and she seems to have been left with blurred and pixilated vision. Even though it has improved somewhat in 2016 it doesn’t seem to be doing much better now. She has the neuro appointment at end of this month and I will ask for a referral to Moorfields Neuro Opthalmic, London, but I don’t know whether there is further treatment for this. She finished steroids in Nov 2015.
