It will now be easier for ophthalmologists and optometrists to track changes in the eye, courtesy the new tool which is available online.

This online app uses the MatchedFlicker interface and automated alternation flickering (AAF) technology to make a comparison of fundus images.
The tool uses alternating superimposed images and this allows better and faster comparison to enable specialists to spot changes in the fundus photographs.
By subscribing to this technology users can access this application which has been cleared for use both in USA and Europe.
