I would suggest going to see a neuro-otologist and someone with vestibular certification in vision therapy. Your symptoms (nystagmus, tracking issues, dizziness) all sound like classic vision-vestibular dysfunction they might be able to help. :)

Yay! PM me if you need more details on the specialties, not sure if you're in the US or not.

I'm a girl twin and I LOVE mine. We get along great just like you guys seem to. shrug

Why haven't you done vision therapy if that could help you gain stereo?

Edit: Just saw your comment below, would stroooongly encourage it to anyone who has this issue, the brain is very plastic and these people* are specialists in retraining it to see in 3-D. Just try it!

*Optometrists trained to do vision therapy - behavioral or developmental optometrists specifically, it's like a specialty within optometry. See COVD.org for more info. They can also help with poor peripheral vision, eye-hand coordination, visual imagery/memory, etc. PM me with questions, I'm not paid to talk about this but I'm good friends with someone who does this professionally and have a couple of friends who did did it for similar reasons.

You are correct about VT training the muscles first and then the neural circuitry. COVD.org can help you find a place with people trained in vision therapy, they are the association that regulates the optometrists trained in that. I would be interested to hear what your surgeon has to say if you bring it up - most surgeons are not supporters of vision therapy.
