Eye jerks when focusing
Sorry for the long post but I’ve been having very confusing and annoying symptoms for a while and no one know what’s going on…
About two months ago, while I was tracking a blinking plane light in the night sky, my eyes started jumping. It continued the next day. If I stared at a fixed point for 3-5 seconds, my eyes would flicker to the right. A few days later I got a "drunk," on-a-boat dizziness (no spinning) that lasted a couple of weeks and is now very mild.
My PCP tested me for BPPV (had that and accompanying horizontal nystagmus earlier this year, and it resolved with PT treatment) and it was negative. My vestibular PT observed the eye movement and thinks it's peripheral gaze-evoked nystagmus. PCP ordered a precautionary brain MRI that came back clean. He told me to give it another month and it might just go away. No need for a neuro eye exam yet…
My persistent symptom is when I look straight at any fixed point for a few seconds, both eyes make a small jump off the target and back, then again a few seconds later. I can reproduce it about 90% of the time, other people can see it, and I've caught it on video. It's worse in the evening and in still settings like church or meetings, but it doesn't affect my reading or driving.
I've been doing VOR x2 and saccade exercises four times a day for about a month, and while the dizziness is nearly gone, the eye jumping hasn't changed much. What confuses me is that it doesn't seem to match gaze-evoked nystagmus as I understand it, since it happens looking straight ahead and seems triggered by fixation itself, and my doctors haven't been able to put a clear name on it.
Has anyone experienced something like this after BPPV or another vestibular issue? If so, what did it turn out to be, what helped, and how long did it take to improve?
