I would love to hear more about what kind of other specialists you have seen and your timeline of symptoms.
The reason I am asking is because I worked in ophthalmology with 10 specialists, one being a pediatric ophthalmologist. We had a patient present with SEVERE double vision. TRUE double! He had 4 diopters (so a big old chunk of space glasses make up make his eye physically appear straight) So we did all the research, dove into primary care, ran labs, and we were at a loss!! There was no test i could do, nothing came up on MRI, CT you name it, I did it, to figure out where this onset of double vision came from!
So I partnered with multiple people, one at a time.

What it was his sinuses. He had a very elusive, rare type of sinusitis giving him 4 diopters of prism for double vision!!
It wasn’t his brain or eyes, it took effort looking outside our scope of practice.

Looking at everything, after doing diagnostics correctly is important and key. I have a great list of ophthalmologists and ENT I’d be happy to share with you. I’d also love to hear more so I could better assist your health!( I’ve had the same nasal surgery, you went through a lot for worsening results!) so I think it’s time, let me know how I can help!
