I also have bilateral monocular diplopia. My prescription changes roughly every 2-3 months since it started and it hasn’t stopped changing yet. Stress aggravates it a lot. The doctors have not found the source, and they admit it could be both bilateral monocular as well as binocular but they say “that’s like winning the lottery”. I have an abnormal VEP which they tell me to ignore. Every optho I’ve gone to says my eyes are completely healthy. My prescription changes, however, show a spike in farsightedness that slowly returned to normal over roughly 8 months, but the axis of my astigmatism has completely changed location and power — more than a 90 degree change. Also my OCT shows curvature of the right eye from the normal double-hill to a single hill, but all the doctors have green-red disease and told me the OCT was normal because they just look at the averaged “green” values. When I review OCTs of people who had optic neuritis, the curve and green averages look the same. Also, the doctors interpret white sectors as normal, but I recently found out that it indicates that sector is swollen. It’s difficult to find doctors who actually have had real OCT interpretation training... and you’d be shocked to learn all my doctors are at one of the most notorious hospitals around... sometimes I think it’s getting the right doctor no matter where you go. I have not been diagnosed yet although every classic test has come back positive for MS (mri, oligoclonal, vep); but doctors also investigating neurosarcoidosis. Hope this helps. I just had another OCT but don’t have results yet. If this truly is a thing in MS, I wish they’d recognize it in the literature. Being treated near-abusively by arrogant neuro-opthamologists is zero fun.
