Eye test

hi, I’m looking for advise again. I’ve been for an eye test today as I had double vision. He’s said I need an urgent appointment with a neuro-ophthalmology department. His report says I have a difference in my CD ratios and a dark flat central are on my macula with some drussen over it. Has anyone else had this. I donut have a dx yet and wonder if this points toward ms with my other symptoms ( falling over, dropping things and difficulty swallowing) or is this going to be a separate problem altogether.
