Rapid assessments of avoidable blindness in various countries

Status: In progress

Main Objectives

The main objectives of rapid assessments of avoidable blindness (RAABs) are to establish the magnitude and causes of avoidable blindness in an area where we are delivering, or planning to deliver, eye health services. As well as providing important information to help us plan suitable services they also provide useful baseline data that can be replicated 8-10 years later to measure the reduction in blindness or changes in the causes of visual impairment.


Compared to large scale epidemiological surveys, RAABs are a relatively quick and resource-light tool to help programme managers understand the scale and type of visual impairment affecting the population they are responsible for. Once armed with this information, they can plan services in a way that best meets the need of the population. If the RAAB is repeated at a later date (after 8-10 years depending on the scale of service delivery) we should also be able to measure the reduction in visual impairment as a result of those services.

In 2018 we will be conducting a RAAB in Nampula in Mozambique where we will be able to compare the results with a RAAB conducted in 2011 and see if any changes have occurred in the magnitude and type of visual impairment. We will also be  finalising reports from studies conducted in 2017 in new programme districts in Muchinga, Zambia and Singida, Tanzania, and putting their results into practice.
