The preschool children hardly complain about their vision problems. It is of paramount importance to screen them with an objective tool and compare with the gold standard technique.
To compare the values obtained with Plusoptix A09 and cycloplegic refraction in 3-6 years children and agreement to detect refractive amblyogenic risk factors.
A cross-sectional study was conducted in the Outpatient Department of Ophthalmology in a tertiary care hospital. Informed consent from parents and verbal assent from children were obtained. Each subject had monocular vision assessment with Lea symbol chart, stereo acuity measurement with Frisby, refractive screening with Plusoptix A09, squint assessment, and anterior segment evaluation before administering Homatropine hydrobromide (homide) 2% eye drops. Cycloplegic refraction and posterior segment evaluation were performed for final diagnosis.
Descriptive statistics were used to summarize the data. Spearman correlation coefficient and kappa statistics were also employed.
In total, data of 94 children were analyzed. The correlation values obtained between plusoptix and cyclorefraction values for spherical, cylindrical, spherical equivalent were 0.508 ( < 0.0001), 0.779 ( < 0.0001), and 0.407 ( < 0.0001), respectively. Refractive errors were seen in 32% and amblyopia in 17% of eyes. Kappa value was κ = 0.974 in detecting refractive amblyogenic risk factors.
Good correlation was found between the plusoptix and cyclorefraction values. Cylindrical values showed a better correlation. Refractive errors and amblyopia were the major ocular disorders observed. There was significant agreement between the refractive techniques in detecting amblyogenic risk factors.
学龄前儿童很少抱怨他们的视力问题。使用客观工具对他们进行筛查并与金标准技术进行比较至关重要。
比较在3至6岁儿童中使用Plusoptix A09获得的值与睫状肌麻痹验光的值，并比较检测屈光性弱视危险因素的一致性。
在一家三级护理医院的眼科门诊进行了一项横断面研究。获得了家长的知情同意和儿童的口头同意。在给予2%氢溴酸后马托品（后马托品）滴眼液之前，对每个受试者进行了使用Lea符号视力表的单眼视力评估、使用Frisby的立体视锐度测量、使用Plusoptix A09的屈光筛查、斜视评估和眼前节评估。进行睫状肌麻痹验光和眼后节评估以进行最终诊断。
使用描述性统计来汇总数据。还采用了Spearman相关系数和kappa统计量。
总共分析了94名儿童的数据。Plusoptix与球镜、柱镜、等效球镜的睫状肌麻痹验光值之间的相关值分别为0.508（<0.0001）、0.779（<0.0001）和0.407（<0.0001）。32%的眼睛存在屈光不正，17%的眼睛存在弱视。在检测屈光性弱视危险因素方面，kappa值为κ = 0.974。
Plusoptix与睫状肌麻痹验光值之间存在良好的相关性。柱镜值显示出更好的相关性。屈光不正和弱视是观察到的主要眼部疾病。在检测弱视危险因素方面，屈光技术之间存在显著一致性。
