Meet our international team: VP of International Sales, Monika Ranta, Director of Clinical Marketing, Ulrike Rahn, and Sales Manager in the Middle East Area, Ibrahim Almasri.

“As a specialist in both medical and surgical retina, I understood long time ago the important role of ERG in helping to diagnose several diseases. However, the technologies available so far on the market were not user friendly. They were complicated and time-consuming. This is perhaps one of the reasons we have all so heavily relied mainly on imaging. This changed for me after being introduced to the RETeval device."
