摘要

目的探讨基于计算机的光动力学眼球震颤（OKN）分析仪在学龄前儿童视力诊断中的实用性、准确性和一致性。设计对计算机化OKN分析仪与传统e字视力表在学龄前儿童视力评估中的性能进行比较研究。共有138名2 - 6岁的儿童入组，分为5个年龄组：2岁（29名）、3岁（27名）、4岁（28名）、5岁（28名）和6岁（26名）。方法采用眼球震颤仪和E-word视力表检测视力。统计分析包括相关系数计算和卡方检验来评价方法的可检验性和一致性。结果138名参与者中，125名（90.6%）成功完成了计算机化OKN分析仪的测试。不同年龄组的可测量性无显著差异。E-word视力表的可测性较低，为71.0%。眼球震颤仪测定结果与E-word视力表测定结果具有很强的相关性（R = 0.872），两者具有较高的一致性。结论计算机化OKN分析仪是一种可靠、准确、实用的学龄前儿童视力评估工具。它提供了传统方法的非侵入性替代方法，具有高可测试性和与标准视力测试的强相关性，使其成为早期发现幼儿视力障碍的宝贵工具。

Assessing pediatric visual acuity with a computerized optokinetic nystagmus analyzer

Objectives

To investigate the practicality, accuracy, and consistency of a computer-based Optokinetic Nystagmus (OKN) analyzer for vision diagnosis in preschoolers.

Design

A comparative study evaluating the performance of a computerized OKN analyzer against the traditional E-word visual acuity chart in assessing visual acuity in preschool children.

Participants

A total of 138 children aged 2 to 6 years were enrolled in the study, divided into five age groups: 2 years (29 children), 3 years (27 children), 4 years (28 children), 5 years (28 children), and 6 years (26 children).

Methods

Visual acuity was tested using both the nystagmus meter and the E-word visual acuity chart. Statistical analyses, including correlation coefficient calculation and chi-square tests, were conducted to evaluate the testability and consistency of the methods.

Results

Out of 138 participants, 125 (90.6 %) successfully completed the test using the computerized OKN analyzer. There was no significant difference in the measurability across different age groups. The testability of the E-word visual acuity chart was significantly lower at 71.0 %. A strong correlation (R = 0.872) was found between the results from the nystagmus meter and the E-word visual acuity chart, indicating high consistency between the two methods.

Conclusion

The computerized OKN analyzer is a reliable, accurate, and practical tool for assessing visual acuity in preschoolers. It offers a non-invasive alternative to traditional methods, with high testability and strong correlation with standard visual acuity tests, making it a valuable tool for early detection of vision impairments in young children.
