Improve Your Vision Recovery Techniques Now

 

Approximately 30% of all stroke patients suffer from post-stroke visual impairment (Sand KM. Acta Neurol Scand Suppl. 2013). Following a stroke or other neurological injury, various types of vision deficits can occur including the inability to recognize objects, color vision deficits and difficulty with perceiving various types of motion. Approximately 20% of patients experience permanent visual deficits (Romano JG. J of Neurol Sci. 2008).

According to the National Stroke Association, homonymous hemianopia, which is the loss of one half of the visual field in each eye, is the most common visual disorder. Most people who have vision loss after a stroke do not fully recover their vision. Thankfully, some recovery is possible. Treatment and outcomes will depend on the type of vision impairment and its cause.

Suggested Vision Recovery Outcome Measures

  • Albert’s Test – In this test, patients must cross out lines that are placed in random orientations on a piece of paper. Unilateral spatial neglect is indicated when lines are left uncrossed on the same side of the page as the patients motor deficit or brain lesion is located.
  • Behavioral Inattention Test – The BIT, initially called as Rivermead Behavioral Inattention Test, is a short screening battery of tests to assess the presence and the extent of visual neglect on a sample of everyday problems faced by patients with visual inattention.
  • Bells Test – The Bells Test is a cancellation test that allows for a quantitative and qualitative assessment of visual neglect in the near extrapersonal space.
  • Line Bisection Test – The Line Bisection Test is a test is a quick measure to detect the presence of unilateral spatial neglect (USN). To complete the test, one must place a mark with a pencil through the center of a series of horizontal lines. Usually, a displacement of the bisection mark towards the side of the brain lesion is interpreted as a symptom of neglect.
  • Motor-Free Visual Perception Test – The Motor-Free Visual Perception Test (MVPT) is a widely used, standardized test of visual perception. Unlike other typical visual perception measures, this measure is meant to assess visual perception independent of motor ability. It was originally developed for use with children (Colarusso & Hammill, 1972), however it has been used extensively with adults. The most recent version of the measure, the MVPT-3, can be administered to children (> 3 years), adolescents, and adults (< 95 years) (Colarusso & Hammill, 2003).
  • Occupational Therapy Adult Perceptual Screening Test – The OT-APST is a standardized screening measure that enables occupational therapists to test for the presence of impairment in visual perception across each of the major constructs of visual perception and praxis, including the problems most frequently occurring after stroke.
  • Ontario Society of Occupational Therapists Perceptual Evaluation – The Ontario Society of Occupational Therapists (OSOT) Perceptual Evaluation was designed to assist in the detection of perceptual impairment in adults who have experienced brain damage caused by traumatic brain injury or stroke. The OSOT assesses perceptual dysfunction in areas related to basic living skills. The measure is also used to determine the degree of impairment, to monitor change, and to measure the effects of treatment and/or spontaneous recovery. The OSOT has been standardized for use with individuals aged 40-69 years.
  • Single Letter Cancellation Test – The Single Letter Cancellation Test (SLCT) is used to evaluate the presence and severity of visual scanning deficits, and is used to evaluate unilateral spatial neglect (USN) in the near extrapersonal space.
