Ocular Morbidity among Children of Government Schools of Kathmandu Valley: A Follow-up Study
Introduction: Ocular and vision defects are common among school going children. Vision disorders, especially refractive error are the m disability of children and the leading cause of handicapping conditions in childhood. The present study was conducted to find out ocular morbidity among students of government schools of Kathmandu valley.
Methods: In the descriptive and cross-sectional study, 2412 students, comprising of 1114 (46.2%) males and 1298 (53.8%) females were enrolled in to the study from the five government schools of Kathmandu valley from 2012 to 2013. Detailed eye examination included distance visual acuity testing, anterior and posterior segment examinations, retinoscopy and refraction, cover test, near point of convergence, amplitude of accommodation and color vision test. The Chi-square test was performed to analyze the association between ocular morbidity and age and sex. P-value was considered significant at 0.05 for 95% confidence interval.
Results: Majority of children was age group between 11 and 13 years (n=783, 32.5%). A male to female ratio was 0.85. Presenting and best spectacle corrected visual acuity of 6/6 was present in 2257 (93.6%) and 2380 (98.7%) respectively. Total ocular morbidity was observed in 515 (21.4%) subjects. The most common types of ocular morbidity were refractive error in 241 (10%), conjunctivitis in 104 (4.3%) and convergence insufficiency in 82 (3.4%).
Conclusions: Refractive error, conjunctivitis and convergence insufficiency represent the most common ocular morbidities among students of government schools.
