Neonatal at risk factors, visual defects and the preschool child: A report from the Queen Mary Hospital
Insights
Vision screening in four-year-olds found visual defects in 5.9% of children. Early detection of vision problems, like amblyopia, is crucial for effective treatment and better outcomes.
Area of Science:
- Ophthalmology
- Pediatric Health
- Public Health
Background:
- Neonatal risk factors may impact long-term child development.
- Early identification of visual impairments is critical for timely intervention.
Purpose of the Study:
- To assess vision screening effectiveness in four-year-old children.
- To compare visual defect rates between at-risk and optimal perinatal history groups.
Main Methods:
- Vision screening tests were administered to 142 at-risk children and 112 controls.
- Defective vision and strabismus were primary detection targets.
Main Results:
- A total of 5.9% of children exhibited visual defects.
- The at-risk group had a 3.5% defect rate, while the control group had 8.9%.
Conclusions:
- Vision screening identified previously unknown visual defects in nine children.
- Widespread vision screening for preschool children is recommended to prevent conditions like amblyopia.
Abstract:
An experimental group of 142 children aged four years who had experienced neonatal at risk factors and a control group of 112 children whose perinatal histories were optimal had vision screening tests to detect defective vision or strabismus. Five (3.5 percent) in the at risk group and 10 (8.9 percent) in the control group (total 15, 5.9 percent) were found to have a visual defect. Of those, six had already been identified because of a manifest squint. Nine children with defective vision were first identified through the study. The importance of the early identification and treatment of visual disorders, particularly amblyopia, is emphasised, and recommendations are made for more widespread vision screening of preschool children.
