Pediatric Physiologic Diplopia
Double vision (diplopia) is when a person see's two of the same object instead of one. Diplopia can be monocular or binocular. Binocular diplopia occurs when an image falls on non-corresponding parts of the two retinas because of ocular misalignment. Binocular diplopia is typically not caused by a problem with the eye. The double vision is binocular if it completely resolves with closing either eye. Monocular double vision persists if one eye is closed and can be in one or both eyes. Monocular diplopia is typically due to an eye problem and is not caused by a neurological problem. Monocular diplopia is typically seen as a “ghost image” or an overlap of images.
