So I saw my eye doc who couldn't find anything wrong but is scheduling more tests. She has sent me to an orthoptist (sp?) I have had strabismus and a lazy eye from birth which was surgically corrected. Have always had slight binocular Diplopia when looking in certain directions. From my understanding my problem is muscular and was wondering whether this could be the cause of my monocular double vision. It certainly feels like a refractive problem but they can't find a cause. I just feel like I am never going to see normally again :(
