Fundus imaging has become an integral tool in retinal diagnosis. Although single-field fundus
photography covers a vital region of the retina, it leaves a large portion of the periphery
undiscovered.
Ultra-wide-field imaging systems allowed for visualization of peripheral perfusion
abnormalities in myopic eyes that were previously unknown.
In Austria, there are two different wide-field imaging systems available. The first device on
the market was the Optos (Optos PLC, Dunfermline, UK) and several years later the Clarus 500
(Carl Zeiss, Meditec AG, Jena, Germany) was introduced.
