Insights
Childhood blindness prevalence in India is shifting from corneal issues to whole globe abnormalities. Enhanced neonatal eye care and pediatric surgical services are crucial for prevention.
Area of Science:
- Ophthalmology
- Public Health
- Pediatrics
Background:
- Childhood blindness significantly impacts a child's psychological and social development.
- Vision 2020-Right To Sight prioritizes addressing childhood blindness.
- Understanding prevalence and causes is essential for effective intervention strategies.
Purpose of the Study:
- To review the prevalence and causes of childhood blindness in India.
- To identify trends in the etiological factors of childhood blindness.
- To highlight areas for improved eye care services for children.
Main Methods:
- Extensive literature search for studies on childhood blindness prevalence and causes from 1990 onwards.
- Inclusion of community-based and blind school studies across India.
- Manual cross-referencing and expert consultation to supplement data.
Main Results:
- Five community-based prevalence studies, including two on refractive errors, were identified for children under 16.
- Blind school studies indicate a shift in causes from corneal conditions to whole globe abnormalities.
- Despite healthcare advancements, significant challenges remain in addressing childhood blindness.
Conclusions:
- The causes of childhood blindness are evolving, necessitating updated intervention approaches.
- Timely neonatal eye care, pediatric surgical services, and effective refraction strategies are critical.
- Continued efforts are required to reduce the burden of childhood blindness in India.
Abstract:
Childhood blindness is one of the priority targets of Vision 2020-Right To Sight due to its impact on the psychological and social growth of the child. An extensive search was performed to locate research papers on childhood blindness prevalence and its causes in the community based and blind schools, respectively, conducted from 1990 onward up to the present. Cross references were also manually searched along with expert consultation to enlarge the reference data. A total of five community-based studies on the prevalence including two refractive error studies conducted all over India in children less than 16 years were found. The causes of childhood blindness from the available blind school studies revealed that causes of childhood blindness have mainly shifted from corneal causes to whole globe abnormalities. This article highlights that though with the availability of proper healthcare facilities, the trend is changing for the causes but still a lot of effort in the form of timely neonatal eye care facilities, pediatric surgical services and proper refraction strategies is required.
