Hello Liew,
I believe Spatial and Perceptual visual impairments are different
kinds of impairments.

Being visually-spatially impaired means being unable to see the
difference in space and distances between objects. For example, normal
people can tell what is a near and a far object, but an impaired
person might say that these two objects are at the same distance, or
the person could not tell. An impaired person can also look at a
regular dot pattern, but could not correctly tell the distance between
the dots.

Being visually-perceptually impaired means that the brain
misinterprets what someone sees. For example, a person can see a
pencil, but cannot put into mind that it is a pencil or something that
is used to write. This is common in Alzheimer's sufferers, for
example, a sufferer sees an empty chair, but claims that an elephant
is sitting on the chair.

These conditions are not disorders in themselves, but are rather the
effects of certain disorders. These disorders often involve
malfunctions of the brain or any other neurological part causing
disruptions in activities that they handle.

My sources for this information are listed:

Behavioral Neuropsychology - Visual Spatial Disorders

Behavioral Neuropsychology - Perceptual Disorders

Visual and Spatial Disorders

Disorders of visual and spatial processing

Google search terms used:

I hope this has been a most helpful answer. If you need anything else,
or have a problem with the answer, do please post a Request for
Clarification and I shall respond as soon as I can. Thank you.
