Article

More than 35 lectures across seven topics, plus a keynote address, will be featured during the meeting

From 13-14 June, Heidelberg Engineering will hold its 21st International SPECTRALIS Symposium (ISS) in its eponymous hometown of Heidelberg, Germany. The event will be the first ISS held in the newly-opened Heidelberg Congress Center. Following the conclusion of the first day’s scientific programme, attendees may board one of two river boats for a cruise down the Neckar, which promises scenic views of historic Heidelberg.1 The Queen Silvia will offer a seated dinner cruise, and a smaller boat alongside will offer food, drinks and music.

Both days of the meeting will feature welcome messages from course director Frank Holz, MD, FEBO, FARVO. Holz is professor and chair of the Department of Ophthalmology at University of Bonn, Germany. During the ISS, he will serve as co-chair for two sessions, and will present his own lecture, sharing results from the MACUSTAR study demonstrating imaging-based progression markers in intermediate AMD.

Below, find the schedule of topics, including programme chairs, for the ISS.2 For more information about the ISS, including information on digital poster presentations, tours of the SkyLabs tower and registration, access the ISS website here.

Friday

Welcome address from course director Professor Frank G. Holz

Oculomics

Chaired by SriniVas R. Sadda, MD, FARVO, and Giovanni Staurenghi, MD, FARVO, FEBO

10:00 to 11:15

Lecture topics will include mechanistic and biomarker discovery, unlocking systemic insights with multimodal retinal imaging in the NICOLA study, approaching neurodegeneration with a focus on corneal imaging, and more.

High-resolution OCT

Chaired by Balwantray Chauhan, PhD, and Leopold Schmetterer, MSc, PhD

11:45 to 13:00

Lectures will address many challenges and opportunities in optical coherence tomography (OCT), including high-res OCT of atrophic and precursor lesions in AMD, unveiling new insights in diabetic maculopathy with high-res OCT, first reactions to a new high-res imaging platform.

New Technology

Chaired by Prof Holz and Adnan Tufail, MBBS, MD, FRCOphth

14:30 to 15:45

Topics in this session include holographic OCT for retinal function, in vivo functional imaging of singular retinal ganglion cells with two-photon imaging, use of fluorescence lifetime imaging ophthalmoscopy (FLIO) to study silent disease progression in Alzheimer, Parkinson and MS and other topics.

AMD and GA

Chaired by Karl Csaky, MD, PhD, and Robert P. Finger, MD, PhD

16:15 to 17:30

Multiple presentations using the MACUSTAR data to better understand retinal function and structure, using OCT-determined anatomical features as clinical trial endpoints, and more

Keynote: A journey into space

From 17:45 to 18:30, two team members from NASA, the US-based National Aeronautics and Space Administration, will deliver the keynote address, “A journey into space: Völlig losgelöst!”

Warren “Woody” Hoburg reported for duty as part of the NASA astronaut class of 2017. He holds a bachelor’s degree in aeronautics and astronautics from the Massachusetts Institute of Technology (MIT) and a doctorate in electrical engineering and computer science from the University of California, Berkeley. At the time of his selection for the astronaut programme, he was an assistant professor at MIT. Astronaut Hoburg launched to the International Space Station as Pilot of NASA’s SpaceX Crew-6 mission in March 2, 2023 and has logged a total of 186 days in space on his first flight.3

Tyson J. Brunstetter, MBA, OD, PhD, FAAO, FAsMA, is a US Navy aerospace optometrist at the NASA Johnson Space Center in Houston, Texas. He earned his OD, MS and PhD from the Ohio State University.4 He the clinical lead for NASA’s research into spaceflight-associated neuro-ocular syndrome (SANS), a condition which is common among astronauts, especially during long-duration missions.

Saturday

Welcome note from course director Professor Frank G. Holz

9:00

Artificial intelligence

Chaired by Roberto Gallego Pinazo, MD, PhD, and Seung-Young Yu, MD, PhD

9:30 to 10:30

Presentations in the artificial intelligence (AI) session will address use of AI in FLIO (including findings from the AI-READI project), AI-based evaluation of dry AMD biomarkers and fluid monitoring in nAMD and GA.

Retina

Chaired by Anat Loewenstein, MD, and Ursula Schmidt-Erfurth, MD

11:00 to 12:30

Topics will include pearls for avoiding misdiagnosis when encountering hyperreflective vitreous opacities in children, OCT and OCT-A in patients with sickle cell retinopathy, OCT-based outcome measures in paediatric gene therapy, and more.

Distributed care

Chaired by Prof Holz and James Talks, MA, MB Bchir, MRCP, FRCOphth

14:00 to 15:30

Topics in the final session include remote patient monitoring, the continued relevance of multimodal imaging, extreme telemedicine during long-duration space travel and closing the “gaps” between hospitals and communities with retinal imaging.
