Abstract

PURPOSE

To study the diagnostic accuracy and effectiveness in children of a new autorefractor with eye-tracking capability.

METHODS

Children aged 3-17 years were tested with a Marco Nidek ARK-560A autorefractor before and after cycloplegia. Cycloplegic manifest refractions were conducted on the more cooperative children. Measurements were converted to vector representations M (sphere), J0, and J45 (cylinder) by Fourier analysis and compared before and after cycloplegia for autorefractor measurements and clinical manifest and retinoscopic determinations.

RESULTS

A total of 88 subjects were included. Autorefractor measurements were successfully obtained on all subjects. Before cycloplegia the mean spherical portion of the refractive error by autorefractor measurement (AR Dry) averaged 0.29 ± 0.75 D less hyperopia than the clinical manifest refraction (P < 0.005). After cycloplegia, mean autorefractor measurements (AR Wet) demonstrated 1.03 ± 0.84 D more hyperopia in the spherical component than AR Dry (P < 0.001). The spherical component of autorefraction and clinical measurements after cycloplegia were not statistically different, but the J0 astigmatic findings differed by 0.13 D ± 0.25 (P < 0.0003). For the 27 children under 8 years of age, precycloplegic autorefractor findings differed from manual cycloplegic retinoscopy by 1.48 D ± 1.13 for sphere (P < 0.001) but were not statistically different for astigmatic parameters.

CONCLUSIONS

Autorefractors can estimate manual retinoscopy values in children and may prove useful in the office setting in evaluating pediatric patients. Autotracking allowed successful acquisition of measurements in all subjects.

摘要

目的

研究一种具有眼动追踪功能的新型自动验光仪在儿童中的诊断准确性和有效性。

方法

对3至17岁的儿童在睫状肌麻痹前后使用Marco Nidek ARK-560A自动验光仪进行测试。对更配合的儿童进行睫状肌麻痹后的显验光。通过傅里叶分析将测量值转换为矢量表示M（球镜）、J0和J45（柱镜），并比较睫状肌麻痹前后自动验光仪测量值、临床显验光和检影验光结果。

结果

共纳入88名受试者。所有受试者均成功获得自动验光仪测量值。在睫状肌麻痹前，自动验光仪测量的屈光不正球镜部分（AR Dry）平均比临床显验光少0.29±0.75 D远视（P<0.005）。睫状肌麻痹后，自动验光仪平均测量值（AR Wet）显示球镜成分的远视比AR Dry多1.03±0.84 D（P<0.001）。睫状肌麻痹后自动验光和临床测量的球镜成分无统计学差异，但J0散光结果相差0.13 D±0.25（P<0.0003）。对于27名8岁以下儿童，睫状肌麻痹前自动验光仪结果与手动睫状肌麻痹检影验光的球镜相差1.48 D±1.13（P<0.001），但散光参数无统计学差异。
