Retinal migraine and permanent vision issues?
TL:DR has anyone had a retinal migraine cause permanent vision changes or is my retina specialist gaslighting me?
I have had migraines my whole life. Like, my earliest memories are waking up with a migraine and throwing up in bed. As I got older they transformed into complex migraines with aura and ultimately to hemiplegic status, now fortunately well managed thanks to zepbound, ajovy, and ubrelvy in my late 30s. However, three months ago I woke up to what seemed like was going to be a migraine aura, with a blind spot about the size of four digits on my credit card if held at normal "reading distance" (my best description). I waited for it to change to colorful zig zags, to grow and move, for any other symptoms to appear, but nothing happened. It also notably was only in one eye. The blind spot didn't grow or change or move for hours, so I called my eye doc to ask to be seen that day in case there was something wrong with my eye.
They did a battery of exams and tests, and found no issue. They sent me to get an MRI, nothing. They sent me to a retina specialist, who DID find a spot on my retina that is in the right spot to be causing a blind spot in that location (it's just up and to the left from my focal point. For example when reading this text, the word up two rows and two or three words to the left of where I'm looking is gone). He had no better explanation for what it might be and chose to diagnose it as a retinal migraine. I disagreed, knowing visual migraine issues are not permanent. However, I am but a lowly HR masters graduate and not a Harvard educated ophthalmologist, so I let it go for the time being. I agreed to come back in three months for another scan under the assumption the blind spot would be gone AND the spot on my retina would be gone. That followup is in two weeks and the blind spot is completely unchanged.
Is this doctor wrong like I think he is? Has anyone had a retinal migraine that actually caused permanent vision changes, or is he using my history of migraine as an excuse to not do more research into finding the true explanation?
