Global Action Plan Indicators – the data in full

Data in the table below provides country information that relates to the main monitoring indicators contained within the Universal Eye Health: a Global Action Plan 2014 – 2019 (GAP).

You can use the filters in the table below to search by Super Region, GBD Region or country; you can re-order the data based on any column header; and you can search for individual years (eg from 2015 to 2015) or a range of years (eg from 2010 to 2015). You can show more rows at once by using the ‘Show ‘XX’ entries’ selector, and you can turn columns off/on using the ‘Columns’ tool to the right of the search field. Not sure how this works?

*ECSAT = Eye Care Service Assessment Tool; EHSA = Eye Health Systems Assessment

The principle is to use the ‘most recent credible data’. It has not been possible to collect credible data for all countries for all the indicators so only data considered robust is shown.

Data has been drawn from a number of sources:

  • Data presented by Member State representatives at regional WHO/IAPB GAP meetings held in 2014, 2015 and 2016
  • Data from National Prevention of Blindness co-ordinators provided to IAPB in 2015 and 2016
  • Data from a research study on the numbers of eye health professionals in 21 African countries conducted in 2013
  • Data from a research study on the number of Ophthalmologists per country conducted in 2012
  • Data from the World Council of Optometry for the number of optometrists including the ECCO Blue Book (2015) for the numbers of European optometrists
  • Data from a research study on eye health care in 14 countries of East and Central Europe conducted in 2009
  • Data on prevalence studies and national Cataract Surgical Coverage (CSC) extracted from the RAAB repository and validated by Dr Hans Limburg

CSC data from 2004 to the present was collected as we wished to include all the national CSC data available for this very important indicator. For all the other indicators only data from 2009 onwards has been used. This year was chosen as the cut off as it relates to the start of an earlier WHO Global Action Plan for the period 2009-13 (WHA Resolution 62.1) and also because some of the indicators in the GAP are shown as ‘within the past five years’; thus 2009 activity falls within this time frame given the current GAP commenced in 2014.

The data on Cataract surgeries and eye health professionals is shown both as an absolute number and as a rate – the number per million of population. The population used as the denominator for these calculations is that for 2012 taken from UN data sources . This can give rise to a discrepancy where the data used in the numerator is not for 2012. However changes in the numerators and the population denominator are very small year by year and accordingly the error is tiny.

This web-based version of the IAPB Vision Atlas includes the full set of all indicators collected. It is updated regularly and shows the most recent and most credible data available. Definitions of all the indicators can be found in the Glossary. A full technical definition can also be found in Appendix 4 of the GAP . Countries are ordered in the table according to which of the seven GBD Super Regions and 21 GBD Regions defined by the Global Burden of Disease study group they fall into.

The 14 main indicators included in the table fall into three broad categories: Cataract surgery, eye health personnel and evidence & planning.

Cataract Surgery

1. The number of Cataract Surgeries performed in the country
2. The Cataract Surgical Rate (CSR; the number of cataract surgeries per million population)
3. The Cataract Surgical Coverage (CSC) shown as a % of persons at both the 3/60 and 6/18 level

Eye Health Personnel

4. The number of Ophthalmologists in the country
5. The number of Ophthalmologists per million of population
6. The number of Optometrists in the country
7. The number of Optometrists per million of population
8. The number of Allied Ophthalmic Personnel in the country
9. The number of Allied Ophthalmic Personnel per million of population

Evidence & Planning

10. Has a population-based epidemiological survey been conducted in the country (2009 or later) to determine prevalence rates and causes of visual impairment and blindness?
11. Has a systems assessment been conducted in the country (2009 or later)?
12. Is there a national eye health/prevention of blindness committee?
13. Is there a national co-ordinator for eye health/prevention of blindness?
14. Is there a current national plan for eye health/prevention of blindness?

This web-based version of the table also shows supplementary information including, the year and source of the indicators. Additional information is shown for some of the indicators including:

  • Epidemiological study – whether the study was at a national, provincial or district level
  • Systems assessment – the type of assessment conducted (EHSA or ECSAT)
  • National Plan – the dates of the current or most recent plan
