Childhood visual impairment due to refractive errors is a significant problem in school children and has a considerable impact on public health. To assess the magnitude of the problem the present study was undertaken among the school children aged 5 to 10 years in Kolkata. Detailed ophthalmological examination was carried out in the schools as well as in the Regional Institute of Ophthalmology, Kolkata. Among 2317 students examined, 582 (25.11%) were suffering from refractive errors, myopia being the commonest (n = 325; 14.02%). Astigmatism affected 91 children (3.93%). There is an increase of prevalence of refractive errors with increase of age, but it is not statistically significant (p > 0.05). There is also no significant difference of refractive errors between boys and girls.
屈光不正导致的儿童视力损害是学龄儿童中的一个重大问题，对公众健康有相当大的影响。为评估该问题的严重程度，本研究在加尔各答5至10岁的学龄儿童中开展。在学校以及加尔各答地区眼科研究所进行了详细的眼科检查。在接受检查的2317名学生中，582名（25.11%）患有屈光不正，其中近视最为常见（n = 325；14.02%）。散光影响了91名儿童（3.93%）。屈光不正的患病率随年龄增长而增加，但无统计学意义（p > 0.05）。男孩和女孩之间的屈光不正也无显著差异。
