The aim was to study and treat ocular disorders in children with learning disabilities (cLDs) and explore associations with their perinatal history.
cLDs attending 11 special schools were examined by a team consisting of an ophthalmologist, optometrist, and a social worker in 2007 and followed up in 2008. The students' intelligence quotient (IQ) and their medical histories were noted. Distant visual acuities were measured using Kay pictures or Snellen's tumbling E chart and complete ocular examination was performed. Students were assessed at the pediatric ophthalmology unit and low vision center, if needed. Statistical analysis was done with SPSS and the Chi-square test for ordinal data.
A total of 664 students were examined, 526 of whom were <16 years of age; 323 (61.4%) were male. A total of 326 (60%) had moderate-to-severe learning disabilities (IQs <50), and the mean IQ was 45.4. Two hundred and thirty-eight (45.3%) had ocular disorder; 143 (27.3%) had an uncorrected refractive error, followed by strabismus in 83 (15.8%), nystagmus in 36 (6.8%), optic atrophy in 34 (6.5%), and congenital anomalies in 13 (2.5%), 103 children had more than one abnormality. Only 12 of the 143 students with refractive errors were using spectacles. A total of 132 (48.7%) children with a history of perinatal insult had ocular problems. Ocular disorders were also common in those with a history of epilepsy, Down's syndrome, and cerebral palsy.
Nearly half the cLDs in this study had ocular disorders and one-fourth had their vision improved.
研究和治疗学习障碍（cLDs）儿童的眼部疾病，并探讨其与围产期病史的关联。
2007 年，一个由眼科医生、验光师和社会工作者组成的团队对 11 所特殊学校的 cLDs 进行了检查，并在 2008 年进行了随访。记录了学生的智商（IQ）和病史。使用 Kay 图片或 Snellen 的滚动 E 图表测量远视力，并进行全面的眼部检查。如有需要，学生在小儿眼科和低视力中心进行评估。使用 SPSS 进行统计分析，并对有序数据进行卡方检验。
共检查了 664 名学生，其中 526 名年龄小于 16 岁；323 名（61.4%）为男性。共有 326 名（60%）有中重度学习障碍（IQ<50），平均智商为 45.4。238 名（45.3%）有眼部疾病；143 名（27.3%）有未经矫正的屈光不正，其次是斜视 83 名（15.8%）、眼球震颤 36 名（6.8%）、视神经萎缩 34 名（6.5%）和先天性异常 13 名（2.5%），103 名儿童有多种异常。在 143 名有屈光不正的学生中，只有 12 名戴眼镜。共有 132 名（48.7%）有围产期损伤史的儿童有眼部问题。有癫痫、唐氏综合征和脑瘫病史的儿童也常见眼部疾病。
在这项研究中，近一半的 cLDs 有眼部疾病，四分之一的视力得到改善。
