Ocular morbidity among primary school children of Dhulikhel, Nepal
Insights
Refractive errors are the most common eye problem in primary school children, affecting 10.08%. This study highlights the need for early detection and intervention for childhood ocular diseases.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Public Health
Background:
- Understanding childhood disease patterns is crucial for developing effective health strategies.
- Ocular health in children is vital for their overall development and learning.
Purpose of the Study:
- To investigate the prevalence and patterns of ocular morbidity among primary school children.
- To identify common eye conditions affecting this age group.
Main Methods:
- A comprehensive eye examination was conducted on 466 primary school children from five randomly selected government schools.
- Standard ophthalmic procedures including visual acuity, refraction, and tonometry were performed.
- Specialized tests like funduscopy and automated perimetry were utilized for selected cases.
Main Results:
- 10.08% of the children (47 out of 466) exhibited some form of ocular morbidity.
- Refractive errors were the most prevalent condition, accounting for 2.36% of cases, with hypermetropia being more common than myopia.
- Conjunctivitis (1.71%) was the second most frequent diagnosis, followed by glaucoma suspects (1.28%) and xerophthalmia (1.07%).
Conclusions:
- Refractive errors represent the leading cause of ocular morbidity in primary school children.
- The findings underscore the importance of regular eye screenings in schools to detect and manage common eye conditions early.
Background:
Knowledge of disease pattern in children can help design preventive and curative strategies.
Objective:
To study the pattern of ocular morbidity among the primary school children.
Subjects And Methods:
All the children of randomly-selected five government primary schools of Dhulikhel were included in this study. A complete eye examination was done in all children including color vision, loupe examination, refraction and Schiotz tonometry. Funduscopy and automated perimetry were done in selected children.
Results:
A total of 466 primary school children were included in the study, of which 466 children 47 (10.08 %) had ocular morbidity. Refractive error was the commonest type of ocular morbidity in 11 (2.36 %). Hypermetropia was the commonest type of refractive error (0.84 %) in contrast to myopia (0.64 %). Conjunctivitis was the second common type of ocular morbidity (1.71 %). Glaucoma suspects accounted for 1.28 %, xexophthalmia 1.07 %, blephatitis 0.85 %, amblyopia 0.43 %, color blindness 0.43 %, conjunctival nevus 0.43 %, glaucoma 0.43 %, and strabismus 0.43 %, while congenital abnormalities were less common.
Conclusion:
Refractive error is the commonest form of ocular morbidity in primary school children.
