Skills in Retinal Imaging, Diagnosis and Therapy Seminar – an overview
4th –5th June 2015
The Royal College of Ophthalmologists, London

This year more than 150 eye care health professionals attended a two-day seminar in London, organised and co-chaired by Professor Heinrich Heimann and Professor Yit Yang.
With a programme that consisted of twenty-six lectures by seventeen speakers, it highlighted the growing clinical application of multimodality imaging and Optical Coherence Tomography (OCT) in ophthalmic practice. There were eight interactive sessions questioning how we translate images in daily practice, and national and international speakers gave us the most up-to-date information on imaging modalities. The seminar was supported by a trade exhibition from leading ophthalmic companies including Topcon, Carl Zeiss and Heidelberg Engineering.
The topics covered ranged from imaging modalities such as reflectance, OCT, FFA and ICG, to the use of diagnostic ultrasound and electro diagnostics. Particularly valuable topics included the ABC of Age Related Macular Degeneration (ARMD) imaging, Macula Telangiectasia, evidence of clinical trial treatments in Retinal Vein Occlusions (RVO), and anti-VEGF therapy for Diabetic Macula Oedema (DMO).
Mr Ethan Priel (MOR Institute, Israel) opened day one with his talk The Wonderful World of Retinal Imaging. This lecture embraced the use of video rather than still images which enabled us, the audience, to view the blood circulation of the eye clearly. Mr Priel concluded the dynamic angiogram in video format is a better aid to understanding pathology.
Both fluorescence and OCT were considered by Mr Priel to be central to the revolution that has taken place in ophthalmic imaging, diagnosis and treatment. Initial OCT equipment resembled arcade machines; the newer models are much smaller and produce high definition images. Advances in wide field multi-colour imaging, wide field OCT, and OCT angiography, now give striking and dramatic images of the vitreous interface (VIR).
Mr Pearse Keane (Moorfields Eye Hospital, London) added to the comprehensive overview of the modalities used in retinal imaging. He discussed the range of image modalities from the 1980s’ scanning laser ophthalmoscopes to the newer models shown in the current trade exhibition.
Dr Werner Inhoffen (University of Tuebingen, Germany) gave a scientific explanation of the new OCT angiography. Combined with swept source OCT, it is a non-invasive imaging technique used to visualise the micro-vascular network. The new product uses a layer-by-layer tissue peeling graphical user interface. Patient comfort was increased as the latest technology requires no dye or dilation with rapid image capture.
Professor Michel Michaelides (Moorfields Eye Hospital, London) gave an extensive in-depth talk on Inherited Macular and Retinal Disorders including Choroiderimia and Retinal Pigmentosia (RP). Study of the progressive Vitelliform Dystrophy (Best disease) has raised the possibility of gene therapy and in severe Stargardt Disease (STGD) patients can be treated with stem cell therapy and retinal implants.
