Will my brain be able to fuse the two images together?

I had corrective surgery to straighten strabismus in my left eye after my TBI. The surgery was 15 years ago but now I see two separate images, and it worsens when I'm stressed or really concentrating.

Answer transcribed from Brightway's Interview with Dr. Bryce Appelbaum

Good question. I would definitely say maybe. What that means is it depends on the type of brain injury and the type of case. If a brain injury is causing eye alignment problems, it would be very hard to suspect an eye muscle strength or length issue unless one of the cranial nerves is impacted. If the eyes are not acting like they're working together, it's almost always a coordination problem. If we’re addressing it from a mechanical standpoint, then we'd say somebody's eyes are turned in because the outside muscle out here needs to be shortened so it's easier for the eyes to stay straight. However, knowing that vision occurs in the brain, it needs to be addressed on a brain basis rather than my muscle basis.


I would urge everyone who goes into any surgery to do a ton of research ahead of time to make sure they know all the complications and the success rates. Strabismus surgery or eye muscle surgery is rare to improve to create a functional cure as well as a cosmetic cure. I think the best-case scenario would be hoping there is a cosmetic cure, but regarding whether the eyes are pointing and looking like they're working together, to me it's so much more important to know how they're acting. I think being able to learn how to use images together, eliminate double vision, and establish order from a disordered visual world, that's kind of the name of the game for vision therapy. On the other hand, the types of eye problems where you're born with an eye in or out or up or down, are usually much more successful with any type of surgical means. If it's something that's acquired, it kind of depends on what caused that eye turn. But again, how the eyes are acting I think is way more important than how they look.
