Exactly. It's impossible to validate that this is really the illusion that the patient is seeing (which is highly unlikely to me) versus the possibility that the patient is making all this up (highly likely).

If they are looking at an already deformed image, that image will be further deformed, no? The deformation 'filter' will be applied to the image too...
