I have double vision in one eye and its monocular diplopia . I got many tests done reveling nothing . Oct , field of view etc were fine. I see fine while looking through a pinhole. The double vision is most prominent when i see white letters on a black background . The second image is diagonally present on the upper side . The second image is like a ghost or shadow image . Doctors that it's psychological and i am actually suffering from a lot of health anxiety.. Is it anxiety or something else
