School eye health programmes

Uncorrected refractive error is the leading cause of vision impairment in children, and spectacles correct the large majority of it [S9]. School-based screening is one of the most effective and cost-efficient ways to reach children over five years old [S8]. Programmes succeed only when screening is linked to spectacles, referral follow-up and continued spectacle wear [S9] [S12].

Key points - Trained teachers screen vision with pooled sensitivity 76.8% and specificity 93.6% [S11]; involving all class teachers was more accurate and cheaper than using a few selected teachers in a Nepal RCT [S10]. - Referral compliance after school screening is poor (median 43.1%); on-site spectacle provision achieved the highest compliance [S12]. - Smartphone-based screening with sight-simulation cards and SMS reminders raised hospital attendance from 22% to 54% in a Kenyan cluster RCT [S3]. - Ready-made spectacles were non-inferior to custom-made ones for wear at 3 to 4 months in eligible Indian children [S2] and cut cost per child needing spectacles by 58.6% [S6]. - Integrating eye health into an existing school programme performed better than a stand-alone model, but both stopped when funding ended [S7].

Red flags: signs that need urgent action

• In a child: vision not improved by spectacles, which may mean amblyopia, strabismus or other eye disease needing referral [S9].
• In a child: an obvious ocular abnormality found by the teacher [S10].
• In a programme: referral attendance below half of children referred [S3] [S12].
• In a programme: low spectacle wear, recorded in both models in Zanzibar [S7].
• In a programme: dependence on short-term external funding [S7].

Recognise it: who to target

• School-aged children, particularly those over five years old [S8].
• An estimated 13 million children aged 5 to 15 years were visually impaired from uncorrected refractive error [S1].
• Need varies with local prevalence of refractive error, competing conditions and school attendance [S1].
• In India the prevalence of uncorrected refractive error among screened children aged 11 to 15 years was 2.23% [S6].

Confirm it: screening and refraction

• Who screens: trained teachers, where eye-care specialists are too few, provide good-quality and cost-effective screening [S4].
• Threshold: studies using a 6/12 cut-off showed more consistent performance [S11]; the Nepal trial referred children with 6/9 or worse in either eye [S10]; the Kenyan trial referred those with less than 6/12 [S3].
• Age matters: teacher screening sensitivity was 89.29% in younger children but 45.45% in adolescents [S11].
• Tools: Peek Acuity had similar sensitivity to a Snellen Tumbling-E card (77% vs 75%) but lower specificity (91% vs 97.4%) [S3].
• Refraction: studies specifying a cycloplegia protocol in the reference examination reported better screening performance [S11].
• Eligibility for ready-made spectacles in the Indian trial included anisometropia under 1.0 dioptre and acuity with spherical equivalent within 1 line of full correction [S2].

Manage it: running a programme at each resource tier

Before acting on this section, check the national and local guidelines, product information and regulatory approvals that apply where you practise. See the medical disclaimer.

Tier A (school and primary care)

• Train all class teachers and repeat training; success depends on solid practical training and teacher motivation [S10] [S11].
• Secure time in the school schedule and the support of principals, staff and parents [S4].
• Address parents' misconceptions, poor literacy and lack of eye health knowledge [S4], including the belief that glasses harm children's eyes [S1].
• Use reminders and simulation cards to push referral attendance [S3].

Tier B (general eye clinic, optometrist or refraction team)

• Provide refraction and spectacles at school where feasible (compliance 51.8% to 96.0%) [S12].
• Otherwise set up a clear referral pathway (25.0% to 65.7%); health education alone was insufficient (21.3% to 24.5%) [S12].
• Use ready-made spectacles for eligible children and custom-made for the rest [S2] [S6].
• Check spectacle wear; more severe refractive error and worse uncorrected acuity predict higher wear, and girls were more likely to wear spectacles in quantitative studies [S5].

Tier C (specialist centre and planners)

• Signpost children with amblyopia, strabismus and other eye disease to treatment [S9].
• Build government-owned, intersectoral programmes with long-term financing, integrated into school health [S7] [S8].
• Standardise protocols and the measurement of spectacle compliance [S5] [S8].

Pitfalls

• Screening without a plan for spectacles and follow-up [S9] [S12].
• Relying on health education alone to drive referral uptake [S12].
• Assuming teacher screening performs as well in adolescents [S11].
• Ignoring spectacle wear after dispensing [S5] [S7].
• Running a vertical programme that ends with donor funding [S7].

Evidence notes

• The Nepal trial randomised only nine schools [S10]; the ready-made spectacle trial followed children for only 3 to 4 months [S2].
• Diagnostic accuracy of teacher screening depends on the rigour of the reference standard and on teacher training [S11].
• Definitions of spectacle compliance varied widely between studies [S5].
• Not covered by these sources: myopia control in schools, screening of preschool children, and near-vision screening.
