Hemianopsia is a debilitating visual condition that affects roughly 1 in 3 stroke patients. It can also be triggered by a brain injury or brain tumor. To the patient, it’s as if one side of their visual field simply disappears. To a layperson, this is hard to imagine, and even harder to explain. Patients with hemianopia have two major complaints related to this devastating condition: it’s hard to read, and it’s hard to get around without bumping into things (mobility).
During this examination, we’ll determine what functional field of vision a person has left and determine the best way to expand that field of vision.
One option used to help restore some of the field of vision is a vision rehabilitation system known as NOVA Vision. This system takes advantage of the brain’s ability to “rewire” itself. For more information on this go to: http://www.novavision.com/
There are also Field Expanding Gasses. These are special glasses that are fitted for you with a prism in each lens. These prisms bend incoming light so that it reaches the non-damaged section of your visual field.
Glasses that are recommended for those with Hemianopsia are The Peli Lens™. The Peli Lens™ is designed specifically to help with mobility. The Peli Lens™ uses high powered prisms placed in the peripheral vision to expand a Hemianopic patient’s awareness of their blind side by over 30 degrees. There is also a patented oblique configuration available that may make it possible to drive. However, driving depends on your state’s laws.
