Integrating eye care into primary health care

Primary eye care (PEC) is a core part of comprehensive eye care and universal eye health coverage; in most of the developing world it is delivered by primary health workers, and in developed nations by personnel such as optometrists [S4]. Integrating eye health into primary health care is widely endorsed, but the evidence that it works at the primary level remains weak [S2] [S8].

Key points - In 2021 the World Health Assembly endorsed a 40-percentage-point increase in effective refractive error coverage by 2030, which requires refractive services in community and primary care [S9]. - In India, more than 300 vision centres linked to mentor hospitals provide PEC in remote rural areas [S4], within a pyramidal model of primary, secondary and tertiary care [S1]. - In Southern and Eastern Africa, eye health was prioritised nationally but failed to cascade to lower levels, eye care data were inadequate and government funding was limited [S8]. - Asynchronous tele-ophthalmology between community optometrists and hospitals cut false-positive urgent referrals by 59% in a UK cluster RCT [S11]. - A menu of 22 eye health indicators, 7 of them core, was agreed for monitoring eye health within universal health coverage [S6].

Red flags: signs that need urgent action

• In a person: a red eye with danger signs. Most red eyes are benign and treatable in primary care, but some emergent conditions present this way and need immediate referral to an ophthalmologist [S3].
• In a person: conjunctivitis during a respiratory epidemic, which may be an early sign of infection; use extra protective equipment [S5].
• In a child: reduced vision. The main causes in Africa (uncorrected refractive error, amblyopia, cataract and corneal opacities) are avoidable with timely diagnosis [S10].
• In a system: no referral link from primary to specialist eye care [S2].
• In a system: no data. Inadequate eye care documentation prevents planning [S8].

Recognise it: what primary eye care covers

• Refractive and optical care: delivered through school-based, pharmacy and outreach models in the community, and vision centre, health centre and door-to-door models in primary care [S9].
• Health promotion: health education, counselling, vision and eye screening, training, and diabetic retinopathy screening [S12].
• Community roles: health promotion and education; drug and supplement distribution and immunisation campaigns; surveillance, screening and detection; and referral and pathway navigation [S7].
• Barriers for children: lack of availability, accessibility and affordability, plus incorrect health beliefs and poor knowledge [S10].
• Barriers in rural India: uptake of services was lowest among lower socio-economic groups, women and rural populations [S1].

Confirm it: is integration working?

• Use the agreed indicators, which were judged feasible, actionable, reliable and internationally comparable [S6].
• Evaluate delivery approaches: few studies have evaluated refractive service delivery models [S9].
• Check whether integration reaches the lower levels of the system, not only national policy [S8].
• Monitor compliance and follow-up after health promotion, which are recognised gaps [S12].

Manage it: what to do 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 (community and primary health worker)

• Engage community actors, but do not assume this alone builds trust; volunteer programmes struggle to sustain motivation when resources are limited [S7].
• Deliver eye health promotion in schools, clinics, workplaces and community events [S12].
• Recognise red-eye danger signs and refer [S3].
• During epidemics, keep distance, use gloves, masks and shields, and sterilise instruments, as recommended by Indian consensus guidelines [S5].

Tier B (vision centre or district eye unit)

• Provide refraction and spectacles close to where people live [S4] [S9].
• Plan human resources, supply chains, financial sustainability, quality and monitoring [S4].
• Add screening for diabetes and diabetic retinopathy to increase community participation [S1].
• Use telemedicine for emergent cases that cannot be managed at the primary level [S5].

Tier C (secondary and tertiary centre and planners)

• Act as mentor hospitals that link vision centres to secondary and tertiary care [S1] [S4].
• Offer remote review of primary-level referrals; in the HERMES trial a decision was given within 48 hours and time to consultation improved [S11].
• Integrate eye care into all health system building blocks, especially financing, leadership and governance [S2] [S8].
• Train general health cadres and communities, while monitoring quality [S8].

Pitfalls

• Treating integration as a national policy statement without implementation at lower levels [S8].
• Training general cadres without checking quality of care [S8].
• Relying on volunteers without resources to sustain them [S7].
• Expecting AI triage tools to work everywhere; one model could not process images from 48.5% of participants [S11].
• Missing emergent causes of red eye [S3].

Evidence notes

• Thin evidence: most sources are programme descriptions, scoping reviews and expert opinion; the only RCT is from a high-income setting [S11].
• Evidence for integration is weak for service delivery, equipment and supplies, financing, leadership and governance [S2].
• No explicit definition of integration was found in the ECSA-HC review [S8].
• Not covered by these sources: a standard list of primary eye care conditions and treatments, essential medicines and equipment lists, and red-eye danger signs in detail.
