Insights
Preterm children with spastic diplegia (SD) often have visual impairments, especially if they have strabismus. Many also exhibit constructional dyspraxia, a deficit potentially independent of visual problems.
Area of Science:
- Neuroscience
- Ophthalmology
- Developmental Pediatrics
Background:
- Spastic diplegia (SD) is a common form of cerebral palsy affecting preterm infants.
- Visual and visuospatial deficits are frequently observed in children with SD.
- Understanding these deficits is crucial for early intervention and support.
Purpose of the Study:
- To assess ophthalmological status, visual perception, and constructional abilities in preterm children with SD.
- To compare neuropsychological deficits in children with SD against a control group.
- To investigate the relationship between visual impairments and constructional function in SD.
Main Methods:
- Evaluated visual acuity, eye position, stereoacuity, and depth perception.
- Assessed visual perception, visuo-spatial construction, and constructional praxis.
- Compared findings between SD and control groups, with and without strabismus.
Main Results:
- Children with SD and strabismus exhibited poorer visual acuity, stereoacuity, and depth perception.
- Constructional dyspraxia was prevalent in 94.1% of children with SD, regardless of strabismus.
- Visual acuity, eye position, stereoacuity, and depth perception did not significantly predict constructional dyspraxia.
Conclusions:
- Preterm children with SD and strabismus are at significant risk for visual dysfunction.
- Constructional dyspraxia is common in children with SD and may be an independent neuropsychological deficit.
- These findings highlight the need for comprehensive neurodevelopmental and visual assessments in preterm SD.
Objective:
To evaluate ophthalmological profiles, visual perception and constructional function in preterm children with spastic diplegia (SD) and to clarify their neuropsychological deficits in comparison with a control group.
Methods:
Thirty-five SD and 34 control children were investigated for visual acuity, eye position, stereoacuity, depth perception, visual perception, visuo-spatial construction and constructional praxis. Each of the results was compared among the four groups as SD with and without strabismus, and control with and without strabismus.
Results:
Strabismic SD showed worse visual acuity, worse stereoacuity and worse depth perception than the other groups. Constructional dyspraxia was detected in 94.1% of SD either with or without strabismus, while it was rare in the control group. There was no significant contribution of visual acuity, eye position, stereoacuity or depth perception to constructional dyspraxia by stepwise multiple linear regression analysis.
Conclusion:
Strabismic preterm SD children are at high risk for visual dysfunction. Constructional dyspraxia was frequently found in SD children and may be a dysfunction isolated from ophthalmological and visual perceptual dysfunctions.
