In which countries is the Lang-Stereotest® used?
In many countries around the world, Lang-Stereotests® have been regularly used either alone or in combination with other tests for decades, especially in Europe, the USA, Canada, South America, India, China, Asia and as well as in Australia.
The systematic use of spectacle-free Lang Stereotest® has significantly lowered the age threshold for stereopsis screening in screening programmes in many countries.
But in which countries and at what age are stereo vision screenings with the Lang-Stereotest® routinely performed in all children due to regulatory guidelines or orders?
The University of Sheffield's comprehensive EUSCREEN study under the EU's Horizon 2020 research programme provides a detailed answer to this question.
The table below from this study provides an overview of eye screening in various countries around the world, and in particular the use of the Lang-Stereotest®. For each country, the link is to the respective country report as a PDF with much more information and with data on population, birth rate, commissioning of eye tests and guidelines.
In some countries, unfortunately, stereopsis screening is still not performed on children. The list does not claim to be exhaustive.
