Insights
Children with hyperinsulinism show significantly impaired visual perception compared to healthy peers. Early screening for visual perceptual disorders is recommended for children with hyperinsulinism to guide rehabilitation.
Area of Science:
- Pediatric Endocrinology
- Neuroscience
- Ophthalmology
Background:
- Hyperinsulinism involves abnormal insulin secretion leading to hypoglycemia, particularly affecting the brain's occipital lobe.
- Hypoglycemia can cause damage to the occipital lobe, which is crucial for visual perception.
- Understanding visual perception deficits in children with hyperinsulinism is essential for early intervention.
Purpose of the Study:
- To investigate visual perception abilities in children diagnosed with hyperinsulinism.
- To compare visual perception skills between children with hyperinsulinism and a healthy control group.
Main Methods:
- A cross-sectional control study conducted in Isfahan, Iran, in 2020.
- Participants included 20 children (aged 4-13 years) with hyperinsulinism and 20 age- and gender-matched healthy controls.
- The Test of Visual Perceptual Skills (non-motor) Third Edition was used for assessment in both groups.
Main Results:
- Children with hyperinsulinism had a significantly lower mean visual perceptual quotient (80.50±26.74) compared to controls (116.50±7.56) (p<0.001).
- All areas of visual perception were found to be weaker in children with hyperinsulinism than in healthy children.
Conclusions:
- Children suffering from hyperinsulinism exhibit significant deficits in visual perception.
- Routine screening for visual perceptual disorders is recommended for children with hyperinsulinism.
- Early identification can facilitate the implementation of targeted rehabilitation programs.
Objectives:
Hyperinsulinism refers to improper insulin secretion in the presence of low plasma glucose, causing severe and persistent hypoglycemia in infants and children. The brain's occipital lobe, which includes the visual and plays an essential role in visual perception is specifically sensitive to hypoglycemia-induced damage. The present study aims to investigate the visual perception in children suffering from hyperinsulinism and to compare it with the control group.
Materials & Methods:
This cross-sectional control study, conducted in 2020 in Isfahan, Iran, involved 20 children aged 4-13 years with hyperinsulinism and 20 healthy children of the same age and gender for comparison. In both groups, the measuring instrument was the Test of Visual Perceptual Skills (non-motor) Third Edition.
Results:
The mean visual perceptual quotient in the case and control groups was 80.50±26.74 and 116.50±7.56 (p-value<0.001), respectively. The results overall indicated that children suffering from hyperinsulinism were weaker than healthy children in all areas of visual perception.
Conclusion:
Based on the obtained results, it is recommended that children suffering from hyperinsulinism be screened regarding visual perceptual disorders since this screening may be helpful in initiating different rehabilitation programs among these patients.
