Aniseiconics

Aniseikonie (anis, unequal, and eikon, Bild ') is a difference in size between the two images projected onto the retina of the right and left eye. In contrast, an image-size equalization is called iseiconia.

Different image sizes can arise on the one hand if the optical properties of the two eyes differ (anisometropia). This condition is also referred to as dioptric anisecology; the power of the eyes is different.

On the other hand, different imaging variables can be caused by a functional aniseikony. Here, the sensory elements in the retina and visual cortex are differently distributed in the eyes.

A physiological aniseikonia is triggered by fixing an object to the side of both eyes, the object-near eye having a larger retinal image than the non-objective.

For the spatial (stereoscopic) vision, the retinal images of both eyes must be brought into coincidence. With pronounced aniseology, the sensory fusion can no longer compensate for differences in image size. There are then disorders of binocular vision that can cause discomfort. Edit source text
