What are the Accessibility Guidelines for Reading with Hemianopia?

Vision loss caused by hemianopia results in a loss of reading ability as the eyes lose their visual functions. To minimize the visual neglect of the eyes, there are some methods:

What are the Causes of Hemianopia?

The visual cortex resides in the occipital lobe of the brain in the primary cortical region and aids in the conscious processing of visually obtained data. There are multiple causes of hemianopia, including but not limited to:

How to Diagnose Hemianopic Patients?

There are many ways to assess a person’s visual field and determine if there are any missing areas of vision. Diagnostic tools used to identify hemianopic patients include:

Individuals found to have visual field impairments that do not originate from the eyes themselves (such as with conditions like glaucoma) should be evaluated by a neurologist to determine if there are any correlations to brain injuries. If a patient’s eyes are healthy, but they are missing a portion of their visual field, a neurological root cause is more likely.

What are the Treatments for Hemianopia?

There are several available treatment options for hemianopia depending on which type the patient has and how severe the condition is.

Interventions for hemianopia are often focused on the rehabilitation of eye movement with compensatory and restoration therapy.

Different researchers, who deal with perimetry, neurology, and psychiatry, and authors examine this field such as Pambakian, Kerkhoff, Rowe, Peli, Zihl, and Kennard alongside the studies and questionnaires that are conducted in clinical trials and vision rehabilitation.

The Trauzettel-Klosinski Lab, Institute for Ophthalmol Research is a leader in the treatment of the homonymous visual field.

Does Hemianopia Get Better?

Often, when tumors, a stroke, or another type of brain injury results in visual field loss, what has already been damaged cannot be repaired and vision cannot be recovered or restored. However, treatment interventions usually prevent new damage and new loss of vision. Preventative treatment also helps patients adapt to having low vision. Randomized controlled trials of treatment of hemianopsia after stroke with visual search training compared to Fresnel prisms actually excluded roughly half of the potential participants because their visual impairment partially or fully resolved on its own. Sufficient spontaneous recovery of the visual field occurs rarely.

Why Hemianopic Patients Have Difficulties with Reading?

What is the Difference between Central and Peripheral Vision?

Central vision is what you are able to see directly in front of you. If you move your eyes or turn your body, whatever you are looking at straight ahead of you is in your central vision. Your peripheral vision is what you see just outside of your central vision in the corners of your eyes.
