A single oblique muscle problem will cause vision of the deviating eye to turn outwards, be either elevated, or depressed, and twist the eye causing the diagonal misalignment known as torsion. Believe it or not, you're not fusing your central vision of the both eyes, but suppressing vision of your right eye, because you're most likely left brain dominant for language you're not intellectually effected. To prove my point divide your eyes vertically with a folder and look at some text, and you will see the text in your left eye with no torsion, but your brain will see the text in your right eye with torsion, and either a depression, or elevation of vision, now do you really think you're fusing your vision. To further prove I'm correct, try and use a pair of binoculars, and if you see two view ports you're not fusing your vision even at a distance. A Halloween mask works quite nicely too, and you will get double vision. This because either method undoes normal fusion which allows you to produce stereoscopic vision, but you should still be capable of binocular fusion. The double vision occurs because the fovea of each eye now gets an image of whatever you're viewing in central vision which normally should fuse, but since you're suppressing vision of one eye you do not normally experience double vision. Since most ophthalmologists are inept to this problem and do not have the equipment to test, I recommend you see a developmental optometrist who will mostly likely diagnose a convergence problem and prescribe vision therapy, decline this because if your eyes are misaligned vision therapy will not help, but they can put you through a battery of tests for suppression of vision, and determine the which eye muscle is still causing the problem, and refer you to a very good muscle surgeon, because prisms added to your prescription will not correct the torsion either. Good luck, The diagonal misalignment is know as torsion, and is caused by too much tension on either on the inferior oblique muscle, or superior oblique muscle of one eye.
