When I look at something with a white or light background, the image seems to shake. My closet doors and doors in my house are white paneled doors and they shimmer/shake (the raised pattern on the door) if I look at them for more than one second. I also am having difficulty teaching in white-painted (bright white) classrooms - everything in the room seems out of focus, however when I walk out of the room into a not so bright area, my vision seems fine. This happens in any bright room I am in. I seen an opthamologist today and he said my exam looked good - he referred me to a neuro-opthamologist, but the appointment is 2 months out. I am quite concerned. I did have a bad headache (constant) in October that lasted two weeks. I had a MRI done at that time (without contrast) and it was normal. Do you think a MRI with contrast would show something that this cold be from? I have tried closing each eye and looking at the white objects and found it does not shake unless I am looking with both eyes open, but when I look with just one eye - the clarity of my vision isn't as good. Please share your thoughts and suggestions with me. Thank-you
