Alert message

Sara:
Our phase I case study is a young man named Brandon. Brandon was born prematurely and developed retinopathy of prematurity, or ROP. Sometime between the most recent functional vision evaluation and the last eye doctor visit, the retina in his right eye became completely detached. A recent low vision evaluation reported Brandon had no light perception in his right eye, and he had form perception in the left and that his field was restricted to 40 degrees. Brandon's eye report also identified right esotropia and optic atrophy. These ocular conditions may have a large impact on Brandon's ability to take in visual information and get the experience needed to resolve some CVI characteristics.

Lynne:
Along with the ocular visual impairment caused by damage to his retina, Brandon also has a history of having a closed head injury, which is one of those red flags when thinking about visual behaviors a person might have due to neurological differences or changes.

Lynne:
Some other information about Brandon you might want to know is that he uses an object calendar to communicate receptively, has cerebral palsy which affects all of his limbs, uses a wheelchair to move from one place to another, and he has a seizure disorder which is well controlled.

Sara:
Socially, Brandon is super active. He really enjoys verbal and sound related interactions with other people, especially when they make funny noises or talk in silly voices. He engages others in this sort of interaction regularly, and initiates it by greeting them or by laughing and turning his head toward them. He makes specific requests by verbalizing stuff like "Hug," or "Eat."
