Outcome measures
Primary outcome
The primary outcome measures of this study reflect reading performance as well
as perceived reading performance: Words per minute read out loud (((number of
words read-number of errors)/time [s]) x 60), Number of reading errors, Words
per minute read silently ((number of words in paragraph/time [s]) x 60),
Subjective report on reading behavior and participation (index scores),
Subjective report on reading difficulties.
Secondary outcome
Vision-related quality of life questionnaire, Fatigue questionnaire, Training
motivation, Reading history, Education,Sustained attention task, Working memory
task, Long-term memory task, Executive functioning task
Background summary
A common consequence of stroke in the posterior region of the brain is a visual
field defect. People with visual field defects frequently experience
difficulties with reading, such as decreased reading speed, making more errors
or being less able to read for a prolonged time. Reading difficulties due to a
visual field defect have a severe impact on daily life activities, social
participation and reduce quality of life. In The Netherlands, the provided
rehabilitation options for these difficulties are currently not empirically
supported.
Study objective
This project aims to determine the effectiveness of two reading interventions:
Vistra and Rotated Reading. The effects will be investigated on the level of
functions, activities and participation. A nuanced view will be provided as to
which training suits which patient best.
Study design
3-arm randomized controlled trial
Intervention
The goal of Vistra is to learn patients to compensate for the visual field
defect by training eye movements. Rotated Reading aims to reduce the effects of
the visual field defect by learning people to read in a different direction,
such as vertically or diagonally.
Study burden and risks
The effect measures do not include invasive testing. The effect measures have
no adverse consequences for the participant, nor for their treatment at Royal
Dutch Visio or Bartiméus and there are no risks involved. Therefore, the burden
is unassuming.

Inclusion criteria
In order to be eligible to participate in this study, a subject must meet all
of the following criteria:
* Homonymous visual field defect (at least a quadrantanopia, either right-sided
or left-sided) due to acquired post-chiasmatic brain injury
* At least three months between onset HVFD and the first measurement
* Near visual acuity >= 0.5 with patient*s own current correction
* MMSE score >=24
* Age >= 18 years
* Presence of by patient formulated treatment goal regarding reading
Exclusion criteria
A subject who meets any of the following criteria will be excluded from
participation in this study:
* Additional visual field defect (at least cluster) in ipsilesional visual
hemi-field
* Pre-existing dyslexia/ illiteracy/ low literacy/ other pre-morbid reading
problems
* No clear neurological cause of HVFD
* Presence of comorbid neglect
The following criteria are made on the premise that, when present, they will
impair the ability to successfully followthe intervention:
* Communication difficulties (e.g. severe hearing impairment, no fluent
understanding of Dutch language, severeaphasia as indicated by the Token test)
* Negative advice of treatment team regarding reading intervention
participation, due to e.g. severe psychiatric, cognitive or visual perception
disorders, problems with health, motivation or illness awareness or misuse
ofdrugs/alcohol/medication
* Additional visual disturbances (e.g. diplopia, metamorphopsia, low contrast
sensitivity)
