Training viewing strategies in children with visual impairment
Viewing Strategy Training in Children With (Cerebral) Visual Impairment: From Spontaneous Eye Movements to a Structured Viewing Strategy
This study tests if training can help children with visual impairments learn better viewing strategies compared to children with normal vision.

What this trial studies
This project aims to investigate the viewing strategies used by children with normal vision compared to those with ocular visual impairment and cerebral visual impairment (CVI). It will measure how these strategies differ and evaluate the effectiveness of training programs designed to improve visual information processing. The study will involve children aged 5-12 years and will assess their visual acuity and cognitive abilities. The ultimate goal is to provide evidence for the effectiveness of viewing strategy training in clinical practice.
Who should consider this trial
Good fit: Ideal candidates include children aged 5-12 years with normal vision, ocular visual impairment, or cerebral visual impairment.
Not a fit: Patients with severe developmental disorders or psychiatric problems may not benefit from this study.
Why it matters
Potential benefit: If successful, this training could significantly enhance the visual processing abilities of children with visual impairments.
How similar studies have performed: While viewing strategy training is commonly used in practice, there is currently no scientific evidence supporting its effectiveness, making this approach relatively novel.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion criteria typically developing children with normal vision: * Age 5-12 years * linear distant visual acuity of 0.1 logMAR or better * Verbal IQ above 70 * Absence of developmental disorders or psychiatric problems like ASS or AD(H)D Inclusion criteria for children with ocular visual impairment: * Age 5-12 years * Children with linear distance visual acuity better \<=1.3logMAR and \>0.1 logMAR * Intact central visual field (at least \> 30 degrees) * Children with a verbal IQ above 70 * Absence of developmental disorders or psychiatric problems like ASS or AD(H)D Inclusion criteria for children with cerebral visual impairment: * Age 5-12 years * Linear distance visual acuity \<=0.3 logMAR * Having the diagnosis CVI (verified by ophthalmologists) * Children with a verbal IQ above 70 * Absence of psychiatric problems like ASS or AD(H)D Additional inclusion criterion for study 2 (evaluating training effectiveness): children with (cerebral) visual impairment should have an indication for viewing strategy training. Training should not be indicated if children have no problems performing academic tasks (i.e. when speed and accuracy of visual processing is within the normal range). The age range for study 2 is 5-9 years. Exclusion criteria: * Children with VI: linear near visual acuity \>1.0 logMAR * Children with visual field defect \< 30 degrees * Children with a verbal IQ below 70 * Children who attended a form of vision training in the past two years * Children with psychiatric problems like ASS or AD(H)D * Auditory impairment or language impairments * Major life events during training
