AFB’s Web site devotes a section to vision impairment that’s tied to brain injury, commonly referred to as cortical visual impairment or cerebral visual impairment, the organization says.

Cliff or Step?

Read “Posture-Specific Learning at the Edge of a Drop-Off” by Kari S. Kretch and Karen E. Adolph, New York University, to learn about how infants’ vision and perception evolve as they experience independent mobility. (PDF)

North American Neuro-Ophthalmologist Society (NANOS)

NANOS says its members specialize in visual problems related to the nervous system. This Web site can help to locate local neuro-ophthalmologists, which can be a challenge. This specialty, like seating & mobility, seems to be a small one.

Orientation & Mobility Specialty

According to VisionAware, this specialty was created after World War II to help soldiers blinded in battle. Among the breakthroughs was a longer, lighterweight cane to facilitate independent travel. O&M specialists teach clients “orientation” skills (where you are, where you want to go) and “mobility” skills (safe, efficient movement from place to place).

Visual Field Neglect

This page from the Optometrists Network describes hemianopsia — aka, hemi field loss — in which patients with brain injury lose their side vision to the left or right. Visual field neglect is a further complication: Patients with hemianopsia aren’t aware of the field loss and don’t compensate accordingly…but prompting and training can help.
