Insights
Children with cerebral visual impairment (CVI) experience significantly lower vision-specific quality of life (VS-QOL). Strabismus in CVI patients further impacts family well-being, highlighting the need for targeted interventions.
Area of Science:
- Ophthalmology
- Pediatrics
- Neuroscience
Background:
- Cortical or cerebral visual impairment (CVI) is a primary cause of vision loss in children.
- Limited data exist on vision-specific quality of life (VS-QOL) in pediatric CVI patients using validated assessments.
Purpose of the Study:
- To evaluate VS-QOL in children diagnosed with CVI.
- To utilize the Children's Visual Function Questionnaire (CVFQ) for assessment.
Main Methods:
- Prospective recruitment of 43 children with CVI (ages 1-12 years) and 20 typically developing controls.
- Administration of the CVFQ to parents of all participants.
- Comparison of CVFQ scores between CVI patients and controls, and correlation with clinical findings in CVI patients.
Main Results:
- Children with CVI demonstrated significantly lower overall and subscale CVFQ scores compared to controls (p < .0001).
- A borderline association was found between visual acuity and overall/competence CVFQ scores in CVI patients (p = .07).
- CVI patients with strabismus reported significantly worse family impact scores (p = .04).
Conclusions:
- CVI significantly diminishes VS-QOL in affected children.
- Strabismus may exacerbate the impact of CVI on families.
- Further research is needed to correlate functional vision with VS-QOL and develop CVI-specific quality-of-life measures.
Introduction:
Cortical or cerebral visual impairment (CVI) is a leading cause of pediatric visual impairment. However, there are limited data using validated assessments of vision-specific quality of life (VS-QOL) in these patients. The purpose of this study was to assess VS-QOL in children with CVI using the Children's Visual Function Questionnaire (CVFQ).
Methods:
Children with CVI (ages 12 months to 12 years) were prospectively recruited from a single pediatric neuro-ophthalmology clinic at a children's hospital, where a complete ophthalmologic examination was performed. Age-matched typically developing controls were recruited from a web-based recruitment service. Parents of participants completed the CVFQ. Overall and subscale CVFQ scores were compared between children with CVI and controls. Additionally, CVFQ scores were correlated with clinical findings in children with CVI.
Results:
Forty-three children with CVI and 20 controls were included in this study. CVFQ overall and all subscale scores were significantly lower in children with CVI (p < .0001). Among CVI participants, there was a borderline association between visual acuity and CVFQ overall and competence subscale (both p = .07) scores. CVI patients with strabismus had significantly worse scores on the family impact subscale than those without strabismus (p = .04).
Discussion:
CVI profoundly affects VS-QOL in individuals with CVI. Strabismus and CVI may have an additive impact on families. Additional studies are needed to determine whether measures of functional vision correlate with VS-QOL in children with CVI, and also to develop VS-QOL scales that are specific to concerns of families and children with CVI.
Implications For Practitioners:
All members of the multidisciplinary care team for individuals with CVI should be aware of the effect of this diagnosis on VS-QOL in both the child and family. Ultimately, practitioners and researchers should strive to identify interventions to improve VS-QOL in individuals with CVI.
