Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
difference in retinal periphery viewing between the two devices
Extent of retinal periphery area viewing (the difference in periphery area between the two devices). Images of the same patients will be compared to determine the degree of periphery viewing for the two devices.
7 months
Study Arms (1)
Extent of retinal periphery area viewing
OTHERFor the 30 patients fundus photography will be performed using two ultra-wide-field imaging systems.
Interventions
