The purpose of the study was to investigate the relation between the severity of reading disorder and visual functions among children with dyslexia.
The present study included 32 dyslexic children selected from two centers for learning disabilities in Mashhad, Iran. Dyslexics were then classified as mild, moderate, and severe based on an instrument used to determine the severity of their reading disorder. Complete optometric examinations to measure visual acuity, refractive errors, latent and manifest deviations, stereoacuity, and amplitude of accommodation were performed for all participants. The correlation between visual functions among dyslexics and their reading disorder severity was investigated.
The mean age of the participants in this study was 8.1 ± 0.8 years. Among participants, 40.6%, 31.3%, and 28.1% presented with severe, moderate, and mild levels of reading difficulties, respectively. Only exophoria significantly correlated with the severity of reading disorders. No significant correlation was found between other visual functions and the severity of reading disorders in dyslexic children.
We found that higher exophoria at near has a significant correlation with the severity of dyslexia. A complete and detailed eye examination of patients with dyslexia and correcting their visual impairments might be helpful.
本研究旨在调查诵读困难儿童阅读障碍的严重程度与视觉功能之间的关系。
本研究纳入了从伊朗马什哈德的两个学习障碍中心选取的32名诵读困难儿童。然后根据一种用于确定阅读障碍严重程度的工具，将诵读困难儿童分为轻度、中度和重度。对所有参与者进行了全面的验光检查，以测量视力、屈光不正、潜在和显性斜视、立体视锐度以及调节幅度。研究了诵读困难儿童的视觉功能与其阅读障碍严重程度之间的相关性。
本研究参与者的平均年龄为8.1±0.8岁。在参与者中，分别有40.6%、31.3%和28.1%的人存在严重、中度和轻度阅读困难。只有外隐斜与阅读障碍的严重程度显著相关。在诵读困难儿童中，未发现其他视觉功能与阅读障碍严重程度之间存在显著相关性。
我们发现近距离外隐斜程度较高与诵读困难的严重程度显著相关。对诵读困难患者进行全面详细的眼部检查并纠正其视力障碍可能会有所帮助。
