|September 1, 1989
Summary
A study of 5135 children in Jodhpur found xerophthalmia prevalence at 9.89%. Early detection of night blindness (XN) and Bitot
Area of Science:
- Ophthalmology
- Public Health
- Pediatrics
Background:
- Xerophthalmia, a leading cause of preventable childhood blindness, is often linked to Vitamin A deficiency.
- Early detection and intervention are crucial to prevent irreversible vision loss.
Purpose of the Study:
- To determine the prevalence of xerophthalmia in school children aged 6-16 in Jodhpur.
- To identify the predominant clinical forms of xerophthalmia in this population.
- To recommend screening strategies for early detection and treatment.
Main Methods:
- A cross-sectional study involving 5135 school children in Jodhpur.
- Clinical examination to diagnose different stages of xerophthalmia, including night blindness (XN), conjunctival xerosis (XIA, XIB), corneal xerosis (X2, X3A, X3B), and xerophthalmia scars (XS).
Main Results:
- The overall prevalence of xerophthalmia was 9.89%.
- Night blindness (XN) and milder conjunctival forms (XIA, XIB) were the most common presentations.
- Severe corneal disease (X2, X3A, X3B) was observed in 8 children, and xerophthalmia scars (XS) in only one.
Conclusions:
- Xerophthalmia, particularly its early stages like night blindness and Bitot's spots, is significantly prevalent in Jodhpur school children.
- Routine school-based screening using XN and XIB as indicators can facilitate early diagnosis and timely Vitamin A therapy.
- Prompt intervention is vital to prevent progression to corneal disease and irreversible blindness.
