Abstract

Objectives

A decrease in vestibulo-ocular reflex (VOR) gain can lead to retinal slip, negatively impacting visual acuity. During reading, eye movements are essential for smoothly transitioning between lines and words. Impaired VOR may disrupt these movements, resulting in additional corrective actions and affecting reading speed. This study aims to explore the relationship between dynamic visual acuity and rapid naming skills in children with dyslexia, compare dynamic visual acuity between children with dyslexia and neurotypical children, and assess gender-related differences.

Methods

Dynamic visual acuity was assessed using a functional head impulse test, followed by a rapid naming test.

Results

A moderately significant relationship was found between left lateral (LL) 5000°/s² and the number naming test (r_s = −0.589, p = 0.027), as well as between LL 5000°/s² and the color naming test (r_s = -0.581, p = 0.029). A moderately significant relationship was observed between the right lateral(RL) 7000°/s² and the object naming test (r_s = −0.593, p = 0.033). Significant differences were observed between neurotypical children and children with dyslexia in the following tests: right lateral (RL) 5000°/s², RL general percentage, left lateral (LL) general percentage, right anterior (RA) 3000°/s², right anterior(RA) 6000°/s², right anterior (RA) 7000°/s², RA general percentage, left anterior (LA) 5000°/s², right posterior (RP) 3000°/s², RP 5000°/s², RP 7000°/s², and RP general percentage. In children with dyslexia, differences were observed based on gender in the LA 7000°/s², RP 6000°/s², RP 7000°/s² and RP general percentage tests.

Conclusion

Children with dyslexia had lower dynamic visual acuity, and girls were more markedly affected. In addition, a moderately negative association was observed between dynamic visual acuity and rapid naming time in children with dyslexia.

动态视敏度对学龄期阅读障碍儿童快速命名的影响

目的前庭眼反射（VOR）增益降低可导致视网膜滑动，对视力产生负面影响。在阅读过程中，眼球运动对于流畅地在字里行间转换至关重要。受损的VOR可能会扰乱这些运动，导致额外的纠正行动并影响阅读速度。本研究旨在探讨阅读障碍儿童动态视觉敏锐度与快速命名能力的关系，比较阅读障碍儿童与正常儿童动态视觉敏锐度的差异，并评估性别差异。方法采用功能头脉冲测试和快速命名测试评估动态视力。结果左侧（LL） 5000°/s2与数字命名检验（rs = - 0.589, p = 0.027）、左侧（LL） 5000°/s2与颜色命名检验（rs = -0.581, p = 0.029）存在中度显著相关。右侧（RL） 7000°/s2与物体命名测试之间存在中等显著性关系（rs =−0.593,p = 0.033）。神经正常儿童与阅读障碍儿童在以下测试中观察到显著差异：右侧（RL） 5000°/s2、RL一般百分比、左侧（LL）一般百分比、右侧前路（RA） 3000°/s2、右侧前路（RA） 6000°/s2、右侧前路（RA） 7000°/s2、RA一般百分比、左侧前路（LA） 5000°/s2、右侧后路（RP） 3000°/s2、RP 5000°/s2、RP 7000°/s2和RP一般百分比。在患有阅读障碍的儿童中，在LA 7000°/s2、RP 6000°/s2、RP 7000°/s2和RP一般百分比测试中观察到基于性别的差异。结论阅读障碍儿童动态视力较低，其中女孩的影响更为明显。此外，在阅读障碍儿童中，动态视力与快速命名时间之间存在中度负相关。

期刊介绍： The purpose of the International Journal of Pediatric Otorhinolaryngology is to concentrate and disseminate information concerning prevention, cure and care of otorhinolaryngological disorders in infants and children due to developmental, degenerative, infectious, neoplastic, traumatic, social, psychiatric and economic causes. The Journal provides a medium for clinical and basic contributions in all of the areas of pediatric otorhinolaryngology. This includes medical and surgical otology, bronchoesophagology, laryngology, rhinology, diseases of the head and neck, and disorders of communication, including voice, speech and language disorders.
