I have been diagnosed with a dozen different eye conditions over the years, and they all basically came down to the same thing : my left eye does not move. Some doctors said it was the optic nerve (??) damaged due to trauma at birth, others said it was a disorder of the muscle, others said the nerve and muscle were both fine, but they just didn't like each other.

Anyway, I've lived with this for 23 years now. I'm getting a little tired of it. My left eye is always focused inward slightly, although it's much less now than when I was younger. Over the years I've developed a bit of control over it (but I still don't have any peripheral vision on my left side).
I've noticed over the last few months that my left eye is always slightly, squinted?, closed?, I don't know what to call it. My right eye looks more open than my left. It's more common when I'm tired/fatigued. I've been to a dozen opth. since I was in kindergarten, and they've all said that the only solution is surgery. But, they all also gave me a different diagnosis. Apparently, it's always been this way and I just started to notice.
So, has anyone ever heard of anything like this? Any idea on what it could actually be?
