[00:00:01.406]
>>Sara: Our phase I case study
is a young man named Brandon.

[00:00:04.946]
Brandon was born prematurely
and developed retinopathy

[00:00:07.706]
of prematurity, or ROP.

[00:00:10.556]
Sometime between the most recent
functional vision evaluation

[00:00:13.616]
and the last eye doctor visit,

[00:00:15.966]
the retina in his right eye
became completely detached.

[00:00:19.476]
A recent low vision evaluation
reported Brandon had no light

[00:00:23.476]
perception in his right eye,
and he had form perception

[00:00:27.276]
in the left and that his field
was restricted to 40 degrees.

[00:00:32.006]
Brandon's eye report also
identified right esotropia

[00:00:34.876]
and optic atrophy.

[00:00:37.256]
These ocular conditions
may have a large impact

[00:00:39.966]
on Brandon's ability to
take in visual information

[00:00:43.136]
and get the experience needed

[00:00:44.946]
to resolve some CVI
characteristics.

[00:00:47.666]
>>Lynne: Along with the ocular
visual impairment caused

[00:00:52.386]
by damage to his retina,
Brandon also has a history

[00:00:55.576]
of having a closed head injury,
which is one of those red flags

[00:00:59.416]
when thinking about visual
behaviors a person might have

[00:01:02.476]
due to neurological
differences or changes.

[00:01:05.916]
>>Lynne: Some other information
about Brandon you might want

[00:01:07.916]
to know is that he
uses an object calendar

[00:01:10.346]
to communicate receptively, has
cerebral palsy which affects all

[00:01:14.456]
of his limbs, uses a wheelchair
to move from one place

[00:01:17.756]
to another, and he
has a seizure disorder

[00:01:20.846]
which is well controlled.

[00:01:23.476]
>>Sara: Socially,
Brandon is super active.

[00:01:25.746]
He really enjoys verbal and
sound related interactions

[00:01:28.566]
with other people, especially
when they make funny noises

[00:01:31.326]
or talk in silly voices.

[00:01:33.506]
He engages others in this
sort of interaction regularly,

[00:01:36.266]
and initiates it by
greeting them or by laughing

[00:01:39.486]
and turning his head
toward them.

[00:01:41.446]
He makes specific requests

[00:01:43.796]
by verbalizing stuff
like "Hug," or "Eat."

[00:01:47.766]
