Outcome measures
Primary outcome
Sensitivity, specificity, reliability of measurement and test-retest
reliability of Standard Conventional Perimetry, Pupil Perimetry and OCT for
detecting visual field defects
Secondary outcome
To provide evidence for possible mechanisms of reorganizational recovery of the
visual system or signs of adaptive neuronal plasticity in the child suffering
from Cerebral Visual Impairment.
Background summary
Children affected by a Cerebral Visual Impairment often suffer from a visual
field defect which may interfere with learning, reading, and rehabilitation
therapies.
However, there are very few methods for testing visual field in young and/or
neurologically impaired children. Furthermore, scientific studies that compare
the usability of different visual field testing methods in this patient group
are lacking.
Hence, there is little understanding of which methods should be used to examine
visual field defects in these children.
Study objective
To compare different methods for visual field testing in young and/or
neurologically impaired children, to determine which test is most useful in
detecting visual field defects.
Study design
Prospective observational cohort study.
Study burden and risks
Participants will need to be tested with all the subjective and objective
methods for visual field testing thrice mostly during their standard control
visits. All tests are non-invasive, most are part of the standard
ophthalmologic assessment and take 10-20 minutes to complete. As such, there
are no potential risks for participating in this study.
This study is designed to include children, because the difficulties in testing
visual field in young and/or neurologically impaired children do not apply to
adult patients. Therefore, it can only be done using this patient group.
