Low Vision Mapping
Jill Keeffe and Peggy Chiang
Aims of study • To understand the current situation of low vision services
throughout the world (What, where, who, and how services are delivered)
• Identify the critical success factors associated with coverage of low vision services (key attributes that ensure comprehensive low vision service coverage)
• This research will be used to inform the WHO Low Vision Working Group and Vision 2020 (provide priority areas to ensure comprehensive coverage)
Surveythemes
Human resources
Location of services
Type of low vision service provision
Equipment• Devices available as part of low vision services- 88%(84/95)
• Supply source of affordable low vision devices- 65% (55/84)
• Reasons that individuals do not obtain low vision devices:
Funding of low vision services
Barriers to access
Other: lack of awareness, lack of services, poor referral pathways, logistics
Groups of people most likely to miss out on services

Critical factors
Summary
Funding - lobbying the government for ownership, funding mix, national budget & insurance to include low vision (example Cameroon vs. India)
Rehabilitation workers – primary level care i.e. outreach & community based rehabilitation services by mid level ophthalmic personnel, HR training, task shifting
Access - government awareness & acceptance, intervention timing, social welfare services, community & family support,
Multidisciplinary services – clinical, education, rehabilitation, comprehensive services integrated with government and other existing services, integration of low vision curriculum into ophthalmic personnel training
External contextual factors – government policy, distribution of resources in urban and rural settings, appropriateness of intervention
Mapping national services
• Prevalence in adults from surveys• Children: WHO estimates using <5MR• Number of HR by cadre – clinical and
rehabilitation• Availability of range of devices• Under-served groups
