2) Alice in Wonderland syndrome (AIWS), or micropsia, is a disorienting neurological condition which affects human visual perception. Subjects perceive humans, parts of humans, animals, and inanimate objects as substantially smaller than in reality. Generally, the object perceived appears far away or extremely close at the same time. For example, a family pet, such as a dog, may appear the size of a mouse, or a normal car may look shrunk to scale. This leads to another name for the condition, Lilliput sight or Lilliputian hallucinations The condition is in terms of perception only; the mechanics of the eye are not affected, only the brain's interpretation of information passed from the eyes.

These split-hand/split-foot malformations are rare limb deformities which can manifest in any number of ways, including cases including only the thumb and one finger (typically the little finger or little finger). It’s also associated with hearing loss. Genetically speaking, it’s caused by several factors, including deletions, translocations, and inversions in chromosome 7.
