To determine whether implementation of comprehensive in-school eyecare results in measurable benefits for children and young people in terms of visual status, classroom behaviours and how well their visual needs are met.
School-based observational study.
PARTICIPANTS & METHODS: 200 pupils [mean age 10 years 9 months, 70% male, majority moderate (40%) or severe (35%) learning difficulty] of a special education school in the UK. A sector-agreed in-school eyecare framework including full eye examination and cycloplegic refraction, dispensing of spectacles (as appropriate) and written reporting of outcomes to parents/teachers was applied. Classroom behaviours were observed and recorded prior to, and after, the in-school eyecare. Surveys were employed to obtain visual histories from parents/teachers. School records and statutory documents were reviewed for diagnostic and learning disability classifications. Visual function and ocular health were profiled at baseline and significant visual deficits identified. Where such deficits were previously unrecognised, untreated or not compensated for (e.g. correction of refractive error, enlargement of educational material) they were recorded as 'unmet visual need'. At follow-up, 2-5 months after initial (baseline) measures, eye examinations, parent/teacher surveys and behaviour observations were repeated. Follow-up measures were used to determine if measurable improvements were evident in visual function, ocular health, the level of unmet need and classroom behaviour following implementation of in-school eyecare.
199 participants completed baseline and follow-up measures. 122 (61%) participants presented with at least one significant visual or ocular health deficit and 90 (45%) participants had at least one unmet visual need. Younger pupils and those with no previous history of eyecare were more likely to demonstrate unmet visual needs at baseline (OR 1.12 95% CI 1.03 to 1.21) p = 0.012; (OR 4.44 95% CI 1.38 to 14.29 p = 0.007 respectively). On follow-up, the number of pupils with unmet visual needs dropped significantly to 36 (18%) (McNemar's test p<0.001). Visual and behavioural metrics of participants without significant visual deficits or whose visual needs were adequately addressed at baseline remained relatively unchanged between baseline and follow-up (Wilcoxon signed rank p>0.05). Where significant refractive deficits were corrected at follow-up, near visual acuity improved significantly (Wilcoxon signed rank p = 0.013), however, poor spectacle compliance was a persistent cause of unmet visual need. Off-task behaviour reduced significantly after actions to address unmet visual needs were communicated to parents and teachers (Wilcoxon signed rank p = 0.035).
The present study demonstrates for the first time measurable visual and behaviour benefits to children in special education settings when they receive comprehensive in-school eye examinations, on-site spectacle dispensing and jargon-free reporting of outcomes to teachers and parents.
确定在学校实施全面的眼保健是否能使儿童和青少年在视力状况、课堂行为以及视觉需求满足程度方面获得可衡量的益处。
基于学校的观察性研究。
英国一所特殊教育学校的 200 名学生(平均年龄 10 岁 9 个月,70%为男性,大多数有中度(40%)或重度(35%)学习困难)。采用了经行业认可的校内眼保健框架,包括全面的眼部检查和睫状肌麻痹验光、配镜(如有需要)以及向家长/教师书面报告结果。在实施校内眼保健之前和之后,对课堂行为进行了观察和记录。采用问卷调查获取家长/教师的视觉病史。查阅学校记录和法定文件,以确定诊断和学习障碍的分类。在基线时对视觉功能和眼部健康进行了评估,并确定了显著的视觉缺陷。如果这些缺陷以前未被发现、未经治疗或未得到补偿(例如矫正屈光不正、放大教育材料),则将其记录为“未满足的视觉需求”。在随访时,即在初次(基线)测量后 2-5 个月,重复进行眼部检查、家长/教师调查和行为观察。随访测量用于确定在实施校内眼保健后,视觉功能、眼部健康、未满足的需求水平和课堂行为是否有明显改善。
199 名参与者完成了基线和随访测量。122 名(61%)参与者至少存在一项显著的视觉或眼部健康缺陷,90 名(45%)参与者至少存在一项未满足的视觉需求。年龄较小的学生和以前没有接受过眼部保健的学生在基线时更有可能出现未满足的视觉需求(OR 1.12,95%CI 1.03 至 1.21,p=0.012);(OR 4.44,95%CI 1.38 至 14.29,p=0.007)。在随访时,未满足视觉需求的学生人数显著下降至 36 名(18%)(McNemar 检验,p<0.001)。在基线时没有显著视觉缺陷或视觉需求得到充分满足的参与者的视觉和行为指标在基线和随访之间基本保持不变(Wilcoxon 符号秩检验,p>0.05)。在随访时,如果对显著的屈光不正进行了矫正,近视力显著提高(Wilcoxon 符号秩检验,p=0.013),然而,不良的眼镜依从性仍然是未满足视觉需求的一个持续原因。在向家长和教师传达解决未满足视觉需求的措施后,课堂上的非任务行为显著减少(Wilcoxon 符号秩检验,p=0.035)。
本研究首次证明,在特殊教育环境中,为儿童提供全面的校内眼检查、现场配镜和向教师和家长提供通俗易懂的结果报告,可使儿童的视觉和行为获得可衡量的益处。
