Alt. of Diplopy

A visual symptom in which a single object is perceived by the visual cortex as two objects rather than one. Disorders associated with this condition include REFRACTIVE ERRORS; STRABISMUS; OCULOMOTOR NERVE DISEASES; TROCHLEAR NERVE DISEASES; ABDUCENS NERVE DISEASES; and diseases of the BRAIN STEM and OCCIPITAL LOBE.

from 'double,' and 'I see.' Visus Duplicatus, Dittopia, Dittopsia, Amphamphoterodiopsia, Amphodiplopia, Ambiopia, Double Vision, (F.) Bevue. An affection of the sight, in which two distinct sensations are produced by the same object, which consequently seems double. Sometimes more than two are seen; but still the disease is termed Diplopia and Suffusio Multiplicans. This affection arises from some derangement in the visual axes, in consequence of which, the images are not impressed on corresponding parts of the retina of each eye. At times, the diplopia affects one eye, or each eye when used alone, owing to some irregularity in the curvature, density, or position of the dioptric media. It is then called Uniocular Diplopia. The diplopia of both eyes has been termed Amphodiplopia and Amphoterodiplopia.

The seeing of single objects as double.

Double vision; the seeing of two images of an object at the same time. It is almost always binocular and the result of squint.
