Insights
This study investigated 812 visually handicapped children, finding boys more affected. Most visual impairments stemmed from prenatal factors, highlighting the need for early intervention to prevent further vision loss.
Area of Science:
- Ophthalmology
- Pediatric Medicine
- Genetics
Background:
- Visual impairment affects children, impacting education and development.
- Understanding the causes of visual handicap is crucial for early intervention.
Purpose of the Study:
- To investigate the degree and causes of visual impairment in 812 children aged 7-21.
- To analyze the prevalence and etiological factors of visual handicap in this cohort.
Main Methods:
- Retrospective analysis of 812 visually handicapped children.
- Categorization of visual impairment causes (genetic, prenatal, perinatal).
Main Results:
- Prevalence of visual handicap was approximately 0.7 per 1000 children.
- Boys were more frequently affected than girls.
- Prenatal factors were the leading cause (30% genetic, 15% pre/perinatal damage, 40% unspecified prenatal).
Conclusions:
- Visual impairment in children has diverse origins, predominantly prenatal.
- Preventing secondary functional amblyopia is critical for visually handicapped children.
Abstract:
812 visually handicapped children aged 7-21 years and educated by black print are investigated with regard to the degree and cause of visual impairment. The rate of visually handicapped children amounted to around 0.7 o/oo, boys being more frequently afflicted than girls. The causes were most often prenatal; 30% of genetic origin, 15% caused by pre- or perinatal damage and 40% of prenatal origin which could not be specified. Some of the more common clinical entities are discussed. The importance of preventing an additional functional amblyopia in the visually handicapped child is stressed.
