There are two types of visual neglect; hemispatial inattention and
homonymous hemianopsia. Patients who suffer from either/both of these disorders
having usually suffered from a traumatic situation affecting the right
hemisphere. The difference between homonymous hemianopsia and hemispatial
inattention is that hemispatial inattention is an attention deficit on one side
of the body where as homonymous hemianopsia is a physical loss of a visual
field in both eyes.
Both hemispatial inattention and
homonymous hemianopsia can not be corrected but can be treated by corrective
lenses and occupational therapy. Patients must become aware of the neglect and
learn how to deal with it accordingly. In recent years, drug therapy has been
used to erect both disorders but had varying outcomes. Some patients recovered
some of their visual field where as other lost more of their visual fields.
