Stroke Flashcards
Visual field deficits related to LEFT hemisphere stroke
★ RIGHT visual field loss
★ abbreviated search pattern that does not extend to the right visual field
★ omissions noted in the blind field
★ reading into a blind field (words appear to end or stop)
★ responds to verbal cues to check
Visual field deficits related to RIGHT hemisphere stroke
★ LEFT visual field loss
★ abbreviated search pattern that does not initiate on the far left visual field
★ difficulty with locating the start of line when reading
★ omissions noted in the blind field
★ responds to verbal cues to check
Hemi-inattention
★ RIGHT hemisphere injury (most common)
★ asymmetrical visual search patterns
★ abbreviated search pattern that does not extend to the LEFT visual field
★ omissions noted on the LEFT side
★ random & unpredictable visual search pattern
★ difficulty conceptualizing space on the LEFT side
★ does not respond to verbal cues to check the left visual field
★ task is completed quickly and client does not check for errors
Visual neglect
★ RIGHT hemisphere injury (most common)
★ most SEVERE form of hemi-inattention which includes left visual field loss
★ asymmetrical visual search patterns
★ abbreviated search pattern that typically does NOT CROSS THE MIDLINE
★ omissions noted on the LEFT side
★ random & unpredictable visual search pattern in the RIGHT visual field only
★ difficulty conceptualizing space on the LEFT side & does NOT elicit head turn to left
★ does not respond to verbal cues to check the left visual field or turn head and eyes to the left
★ task is completed quickly and client does not check for errors
What is perceptual completion in the context of visual field loss?
when the brain fills in missing visual information, making the client unaware of the deficit
How do clients with LEFT hemisphere injury attempt to compensate for visual field loss?
Use of organized scanning patterns & engage visual attention to search the environment
★ involves extending their visual scan into the right visual field
- clients may miss items due to lack of awareness as to how far they should scan
