Overview
Damage to visual cortex on one side of the brain frequently produces a profound and permanent blindness in contralesional space (hemianopia), a debilitating condition that causes enormous suffering for patients and their families.
Detailed description
The over-arching objective of the current proposal is to evaluate the functional recovery of vision in hemianopic (blindness in one hemifield) and quadrantanopic (blindness in one quadrant) patients engaged with a multisensory training paradigm. This will pave the way for clinical trials in which this simple, non-invasive training paradigm can be developed for therapeutic use to treat blindness resulting from cortical damage.
Interventions
- Behavioral Multisensory Rehabilitation
12 research sessions + clinical visits at the time of the first and last session - In each session, there will be a "training phase" in which subjects will be exposed (and respond) to spatiotemporally congruent pairs of visual-auditory stimuli presented within their blinded field, with occasional probes of unisensory visual stimuli on both sides of space. There will also be a "testing" phase during which they are presented with visual stimuli in virtual reality (VR) to assess multiple aspects of
Primary outcome measures
- Change in National Institutes of Health Stroke Scale (NIHSS) score [Time frame: Month 6]
- Change in Activity Inventory scores [Time frame: Month 6]
Eligibility criteria
Inclusion criteria
- Patients will be recruited from the local subject population hospitalized/seen by Ophthalmology, Neurosurgery, and Neurology at Atrium Health Wake Forest Baptist
- diagnosis of stable homonymous hemianopia (>4 weeks) with absence of hemineglect
- a lesion encompassing at least primary visual cortex but sparing parietal cortex, to include lesions caused by an ischemic or hemorrhagic stroke or post-surgical changes due to an oncologic or non-oncologic tumor
- normal or correctable auditory and cognitive function
- willingness to participate in the three-month program
- ability to perform visual discriminations in their intact field
- life expectancy ≥12 months
Exclusion criteria
- diagnosis of an unstable homonymous hemianopia and/or with hemineglect,
- Abnormal or uncorrectable auditory and cognitive function
- unwillingness to participate in the program
- inability to perform the visual testing in their intact field
- life expectancy < 12 months
- Any other condition that would compromise their ability to complete the study.
