What this Trial Is About
Viewing strategies are strategies used to process visual Information. Many children with visual impairment seem to lack systematic viewing strategies. However, it is unknown how viewing strategies differ between children with normal vision and children with (cerebral) visual impairment. In addition, viewing strategy training is often adopted in clinical practice, but till date there is no scientific evidence about effectiveness of this approach. The current project has two goals: (1) to measure viewing strategies used by children with normal vision, children with ocular visual impairment and children with CVI, and (2) to evaluate whether training viewing strategies results in more efficiënt visual Information processing.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Children aged 5 to 12 years
- For typically developing children: normal vision with linear distant visual acuity of 0.1 logMAR or better
- For children with ocular visual impairment: visual acuity better than 1.3 logMAR and greater than 0.1 logMAR, intact central visual field of at least 30 degrees
- For children with cerebral visual impairment (CVI): diagnosed CVI, linear distance visual acuity of 0.3 logMAR or better
- Verbal IQ above 70
- Absence of developmental disorders or psychiatric problems like autism spectrum disorder or ADHD
- For training effectiveness study: children with (cerebral) visual impairment aged 5 to 9 years with indication for viewing strategy training (problems in academic visual processing)
You will not qualify if you...
- Children with visual impairment having linear near visual acuity worse than 1.0 logMAR
- Children with visual field defect less than 30 degrees
- Children with verbal IQ below 70
- Children who attended any vision training in the past two years
- Children with psychiatric problems such as autism spectrum disorder or ADHD
