To date, there is no agreement on what is and what is not AIWS, so some authors  include as part of AIWS symptoms such as dyschromatopsia, entomopia, mosaic vision, palinopsia
, polyopia, visual perseveration, visual allachesthesia, and prosopometamorphopsia.
(Perseveration of visual image even after the causative object is removed from the visual field otherwise described as 'persisting after-images') can result from right occipital damage due to stroke, trauma or tuberculoma.
On the other hand a propagation from the basal region to the lateral occipital and parietal region (through the VO, vSLF, and AF) would create complex illusions like objects that appear disorientated in distance (macroproxiopia, microtelepsia), or be distant and minute (teleopsia), or that have a loss or enhancement of stereoscopic vision or even persistent or recurrent (palinopsia
) (see [6-8] for reviews).

) with risperidone in a patient without previous hallucinogen exposure: possible relation to serotonin 5HT2a receptor blockade.
