PURPOSE
The purpose of the study was to explore the vision status of preschool children aged 3-6 years in Al Riyadh and to identify children at risk of amblyopia.
MATERIALS AND METHODS
This was a cross-sectional population-based study. Visual acuity (VA) was measured using 15-line Lea symbols, refractive error was assessed using the Mohindra near retinoscopy technique, and peak contrast sensitivity (CS) was measured with the aid of the numerical CS test. We recruited 335 children, with their parents' written consent, from 14 kindergartens.
RESULTS
A total of 335 children were recruited; 42 children (13%) exhibited reduced VA (Median [interquartile ranges (IQRs)], 0.00 [0.01]); most were emmetropic (87.7%). Myopia (4.2%), hyperopia (8.1%), and astigmatism (20%) were also observed. Most children had normal CSs. About 14% of children were at risk of amblyopia. It has been observed that 26% of families have some kind of refractive error.
CONCLUSIONS
It is important to perform vision screening of preschoolers. Early detection of abnormalities in refractive errors could help to minimize the effect of visual impairment.
目的
本研究旨在探讨利雅得3至6岁学龄前儿童的视力状况，并确定弱视风险儿童。
材料与方法
这是一项基于人群的横断面研究。使用15行的Lea符号测量视力（VA），采用莫欣德拉近检影技术评估屈光不正，并借助数字对比敏感度（CS）测试测量峰值对比敏感度。我们在获得家长书面同意后，从14所幼儿园招募了335名儿童。
结果
共招募了335名儿童；42名儿童（13%）视力下降（中位数[四分位间距（IQR）]，0.00[0.01]）；大多数为正视眼（87.7%）。还观察到近视（4.2%）、远视（8.1%）和散光（20%）。大多数儿童对比敏感度正常。约14%的儿童有弱视风险。据观察，26%的家庭存在某种屈光不正。
结论
对学龄前儿童进行视力筛查很重要。早期发现屈光不正异常有助于将视力损害的影响降至最低。
