Angela Wright said:By the way, eye misalignment can also happen if there's a tumor growing on the optic nerve or near the eye itself.
I’d really suggest seeing an ophthalmologist just to rule that out and make sure you get a solid diagnosis.
Basically, eye misalignment can stem from pretty much any ocular issue—if we're talking about degenerative changes in the optic nerve, retina, vitreous, lens, or even corneal clouding, you'd usually see some loss of vision at the same time.
If your vision in that eye is still crystal clear (when you cover the other one, of course), it's quite possible we're looking at paralytic strabismus
http://www.mayoclinic.org/?section...=8892&show=1#4 which is caused by issues with the muscles that move the eyes—this kind tends to pop up more often in adults. It could even be Brown syndrome

Could someone please give me a quick rundown of what Brown syndrome actually is?
It involves the sheath of the superior oblique muscle. If that sheath is too short or if the muscle itself is stiff, you won't be able to look upward after looking toward your nose. Usually, it's a congenital thing (something you're born with), though it can show up later due to inflammation, scarring of the tendon, or even a mass near the muscle interfering with how it works. Because the eye can't move in certain directions, people often tilt their heads to compensate. If that's happening, or if the eye drifts when looking straight ahead, surgery might be needed. Lighter cases can sometimes just be monitored since they occasionally improve on their own (especially if it wasn't caused by an injury).

Honestly, I think your best bet is to see a strabismologist—that's the only way to get a definitive answer on what's going on.
