Generating Evidence

Objective 1 of the Global Action Plan addresses the need for generating evidence on the magnitude and causes of visual impairment and eye care services and using it to advocate greater political and financial commitment by Member States to eye health.

Two key actions are identified in the Global Action Plan to pursue this objective:

  1. Undertake population-based surveys on prevalence of visual impairment and its causes – in particular Rapid Assessment of Avoidable Blindness (RAAB), a rapid survey methodology developed at the International Centre for Eye Health (ICEH);
  2. Assess the capacity of States to provide eye care services and identify gaps – over the past couple of years there has been an increased focus on the development of tools that can assess the status of eye health systems in the context of broader health systems, in particular two such assessment tools are known to IAPB to be available and / or in development:
  • Eye Health System Assessment (EHSA) – a tool developed by the ICEH, which complements a more general, USAID funded, Health System assessment tool. 
  • Eye Care Services Assessment (ECSA) – a tool currently being developed by WHO, thanks to funding from the Queen Elizabeth Diamond Jubilee Trust, designed to assist countries to assess their eye care services against the objectives of the Global Action Plan.
