Went to neuro-opthalmologist this week. I have floaty, murky stuff in my vision, some mild double vision at times (ghost images, stacked), and shaky camera kind of vision. Doctor did a very thorough exam, especially looking at field of vision and if I have nystagmus. She could find nothing obvious wrong (the good news), but this doesn't explain my symptoms (bad news). However, she did say she believes my brain and my eyes need to learn to work together again, due to my vestibular problems (testing last summer showed 46% loss on that side). She hopes I still compensate, and improve. My balance is improving, and so is my health overall. Doctor is sending me to retina specialist "just to be sure."
Actually, I'm pretty happy with this answer, even though it's not really an answer . . .
