“…Aichison et al (1990) remarked that several of the people who they examined were wearing wrong spectacles. Schwartz (1977) accepted that there will, by necessity, be a high percentage of failure and a lot of breakage; in this he agreed with Bader & Woodruff (1980). The latter authors found that gross motor behaviour, fine motor behaviour and picture recognition improved, especially in the youngest children.…”

“…The above study also included the only existing evaluation of the effects of corrective lenses on the behaviour of the ID subjects (Bader & Woodruff 1980). The authors proposed that children who had uncorrected refractive errors suffered sensory deprivation, especially those who grew up in institutions because these provide less sensory input than home environments.…”

The present paper reviews studies on the prevalence of visual impairment (VI) in adults with intellectual disability (ID). Every publication describes an alarming prevalence of blindness and VI. Cataract and keratoconus were common. Many cases of poor distance vision were treatable by ordinary spherical or astigmatic glasses, but few people had had such prescriptions. Elderly residents in community and institutional care often did not receive glasses for near vision. Professional assessments disclosed higher prevalences of VI than questionnaires mailed to the care personnel. The prevalence of VI increased dramatically with the severity of ID and with age. Regular professional assessment of eye disorders, visual acuity and refraction are warranted in residents in both hospital and community care.

“…Prevalence for each condition varies widely as studies are based on different populations of handicapped children and different criteria were used to establish the diagnoses. These conditions are not mutually exclusivefor example, 80-86% of children with cerebral palsy have one or more of the above visual disorders.9 10 25 Changes are most evident in the youngest age group.25 Therefore, a reliable estimate of visual acuity in multiply handicapped children is important, to improve vision where possible, to monitor visual development, and to quantify the degree and type of visual impairment. This information can lead to appropriate ophthalmological and/or educational intervention which may improve developmental potential.…”

“…The CCT11 involved four groups of children with VND with a variety of diagnoses attending specialist schools. Children needing spectacles for the first time or revision of their existing spectacles were given new spectacles either immediately, or after a 2-month delay during which the study was conducted.…”

How to help children with neurodevelopmental and visual problems: a scoping review

et al. 2013

View full text Add to dashboard Cite

Children with visual impairment and a condition affecting their neurodevelopment (children with VND) may require extensive and specialised help but evidence on the most effective strategies for visual improvement is lacking. We defined a PICO format (Population, Intervention, Comparator, Outcome) for a scoping review and systematically searched 13 databases. Two reviewers assessed the abstracts for inclusion and a third arbitrated in cases of disagreement. We abstracted data from included studies. We found 4450 abstracts from which we identified 107 papers for inclusion. Of these, 42 related to interventions involving a change in visual input or function: 5 controlled trials, 8 before and after studies and 29 case reports. The strongest evidence supported the provision of spectacles to improve distance or near vision and the use of ultraviolet light as environmental modification for training. Less strong but suggestive evidence supported training/practice routines to improve acuity or oculomotor control. Interventions exist to help children with VND and current recommendations that they are assessed by a vision specialist are supported by the evidence. More information is needed on the effectiveness of training/practice programmes which may promote improved function, and of environmental modifications to facilitate engagement of children with VND with the surroundings.
