The main objective of this study is to obtain percentile curves of monocular and binocular visual acuity on a decimal scale in a Spanish population aged between 3 and 12 years old.
Descriptive, observational and transversal study which included children between 3 and 12 years old without any known eye and/or systemic diseases. The selection of the sample was made by means of a convenience sampling method carried out in three schools and a hospital of the Community of Madrid. Far monocular and binocular visual acuity was measured using the Bueno Matilla vision unit on a decimal scale, both for monocular and binocular tests. The test used was the symmetrical letters test included with this unit. A descriptive statistic was performed and the visual acuity percentile values obtained were 5, 10, 25, 50, 75, 90 and 95.
The visual acuity of 1300 children was evaluated and analysed. In all the percentile curves obtained, an increase in age-related visual acuity has been observed, reaching a value close to the unit for the 50th percentile, around five years and three months of age, under monocular conditions and somewhat earlier in binocular conditions.
Although the type of sampling performed does not allow a generalization to the entire population, these percentile curves may help the paediatric professional to decide the referral of the relevant child to the eyecare professional, so that certain conditions, like amblyopia or the early stages of school myopia may be early detected.
本研究的主要目的是获得西班牙语 3 至 12 岁人群的单眼和双眼视力十进制百分位曲线。
这是一项描述性、观察性和横断面研究，纳入了无已知眼部和/或系统性疾病的 3 至 12 岁儿童。通过在马德里社区的三所学校和一家医院进行的便利抽样方法选择样本。使用 Bueno Matilla 视力计在十进制刻度上测量远距单眼和双眼视力，用于单眼和双眼测试。使用的测试是该装置中包含的对称字母测试。进行了描述性统计，得出的视力百分位值为 5、10、25、50、75、90 和 95。
评估和分析了 1300 名儿童的视力。在获得的所有百分位曲线中，观察到与年龄相关的视力随着年龄的增长而提高，在单眼条件下，大约在五岁零三个月时接近 50 百分位的单位值，而在双眼条件下则更早一些。
尽管所进行的抽样类型不允许推广到整个人群，但这些百分位曲线可以帮助儿科专业人员决定将相关儿童转介给眼科专业人员，以便及早发现弱视或近视早期等某些情况。
