a visual defect in which the shape and size of an ocular image differ in the two eyes.
a difference in size between the images projected on the retinas of both eyes, due to anisometropia or lens corrections of unequal powers; can cause binocular vision difficulties, since the brain attempts to combine two images of different sizes into one image
Condition in which the image seen by one eye differs in size or shape from that seen by the other eye; associated with anisometropia of greater than 4 diopters.
An optical condition in which the images that fall on the retina are of different sizes in the two eyes.
Unequal retinal image sizes in the two eyes, usually from different refractive errors.
A condition in which the image sizes in each eye are different, leading to difficulties in achieving single vision. Symptoms of aniseikonia are headaches and dizziness. Go to Top
A difference in imaging size between the two eyes.
Inequality in size and/or shape of two ocular images in binocular vision.
unequal size and shape of images from one eye.
Aniseikonia is an ophthalmological condition caused by unequal retinal image sizes. This condition is typically the result of unequal refractive errors. Patients experiencing aniseikonia typically have difficulty fusing the images of the left and right eyes causing discomfort, visual confusion and even headaches.
