The 21st International SPECTRALIS Symposium (ISS) – recognised as one of the most prestigious scientific imaging conferences – will bring together global leaders in ophthalmology to explore the latest breakthroughs and future directions in retinal imaging.
Taking place at the new Heidelberg Congress Center in Germany from 13–14 June 2025, this two-day event will bring together delegates and 35 renowned speakers from 12 countries.
This is considered one of the most scientific and influential imaging conferences

Professor Frank Holz.
Under the chairmanship of Professor Dr Frank Holz (Department of Ophthalmology, University of Bonn, Germany), attendees will gain valuable insights into high-resolution optical coherence tomography (OCT), artificial intelligence in ophthalmology, and distributed care models, shaping the future of diagnostics and patient management.
Among the innovations on display, Heidelberg Engineering will showcase the new SeeLuma digital microscope with intraoperative OCT, offering enhanced visualisation and greater insights in the operating theatre.
“This is considered one of the most scientific and influential imaging conferences. What began 21 years ago as a dedicated retinal imaging event has evolved into a comprehensive platform for innovation in ophthalmology. The opportunity to engage with such a distinguished group of experts and discuss emerging therapies in this setting is truly unparalleled,” said Professor Holz.
