Treatments
There is no cure for Cortical Visual
Impairment but there are certain
treatments for this disease. Depending
on the severity, there are certain visual
exercises that can help train a patient’s
brain to connect the object they see.
Patients with CVI may result in
seizures and must take anticonvulsant
medicine with proper monitoring. A
future direction for Cortical Visual
Impairment promotes the urgency to
create better imaging scanners to
further research in preventing,
stabilizing, or cure this disorder.

Cortical Visual Impairment
Functional Implications
Cortical Visual Impairment (CVI) or
currently called Neurological Visual
Impairment (NVI) is a brain disorder
that can occur congenitally or acquired
that affects the visual area. There is a
wide array of severity with CVI
patients. Some patient’s eye exams
may seem normal or minimally
abnormal. However, further
assessments may reflect the specific
disability.
Parts of the Visual System Affected
This impairment affects the pathways
in the back portion of the eye and the
brain.
This is the neural pathway of the eyes to the
brain.
Students prefer to look at old objects,
colorful and objects moving will attract
their eyes. In school, teachers will need
to provide constant repetition and
breaks during activities. In addition,
familiar toys or objects may help a
student in identifying the object.
Teachers must also associate object
with verbal cues.
Effects of the Visual System
Depending on the severity of the
Cortical Visual Impairment, their visual
fields and their depth perception will be
impaired. Children specifically will
have difficulties identifying people,
shapes or objects and may tire easily
since they require a great amount of
energy for visual processing. In some
cases, patients will be able to see colors
and what is presented to them.
However, they will not be able to
understand what they are seeing.
