RIWC 2020 – 21st Retina International World Congress
Retina International World Congress brings together some of the world’s foremost retinal scientists and clinicians along with the global leaders in patient advocacy and peer support. The Nordic Ophthalmology Congress 2020 will take place at the same venue and time as RIWC 2020. During the events we are planning to hold an Usher Syndrome satellite meeting, details to be announced soon. www.riwc2020.is

Inaugural Meeting of Retina International Special Interest Group on Usher Syndrome in Paris, 21 September 2019, Global Usher Awareness Day
At the occasion of Global Usher Syndrome Awareness Day on Saturday 21 September, the USH SIG Committee came together for a meeting in the Fondation de l’Audition in Paris. Dominique Sturz (Austria), Carol Brill (Ireland) and Dario Sorgato (Italy) enjoyed the warm welcome from hosts Marie-Josée Duran and Salma Hazgui of the Institut de l’Audition. Our fourth Committee member Melissa Chaikof (USA) joined the meeting by teleconference, thanks to the fantastic facilities at the venue. We were also pleased to welcome Professor Isabelle Audo of the Institut de la Vision, and Alice Lapujade (France).
The group discussed at great length the structure and strategy of USH SIG and we are happy to outline the following:
1. Proclamation: “We are a patient led group working together towards the provision of up to date relevant information about research and about expert research centers for people living with Usher Syndrome and advocating about the development of therapies for the global Usher Syndrome community.”
2. Establishment of a Scientific Advisory Panel to ensure that information shared by USH SIG on scientific research on Usher Syndrome is accurate
3. Calendar of Events – to keep the Usher community informed of relevant events
4. Communication Strategy – information will be shared in a Newsletter format with national organisations associated with Usher Syndrome
ERN Eye Workshop on Clinical Trials & Research, 21-22 Nov 2019, Strasbourg
The workshop of the European Reference Network for Rare Eye diseases was preceded by the 2nd Sensgènes Annual Day, where the French affiliated center for Rare Sensory Diseases gave an update on the state-of-the-art research (ear and eye) done in France and with international collaboration.
At the ERN Eye workshop member states presented their updates on clinical trials of gene therapies and about access to and reimbursement of Luxturna (the first approved gene therapy for a rare eye disease: LCA due to REP65 mutation). Also treatment options under development in collaboration with international partners were discussed. For information on how to access genetic testing and clinical trials see our resource file about USH subtypes, USH genes and genetic testing below. For more info about clinical trials and full members and affiliated partners of ERN Eye see https://www.ern-eye.eu/map-of-the-centers-and-clinical-trials. An update about new full members will be available in 2020.
Why is genetic testing important? Today, many promising treatments for Usher Syndrome in the lab and even in clinical trial are gene-based. Unless you know your subtype and even your mutation, you cannot know if you are eligible for a clinical trial. There are different types of potential gene therapies. Those that entail replacing the entire affected gene are not dependent on mutation, but some, such as gene editing or drugs that target specific mutations, require knowing not just the gene but also the mutation. In any case a genetically confirmed diagnosis is required to be eligible for clinical trials and also for upcoming treatments that are not mutation-specific. This is also for the patients’ safety, because interventions and treatments can be harmful in cases of differential diagnosis with similar phenotypes (same symptoms).
In the EU most countries’ health plans cover genetic testing if you are referred by your ENT specialist or ophthalmologist or retinal specialist to an expert center providing genetic testing. In some EU countries a hearing disorder diagnosed at newborn hearing screening is an indication for referral to genetic testing (Usher genes included). ERN Eye works on a common registry for Rare Eye Diseases, where member institutions will feed anonymized data with the patient’s consent.
In the US, some insurance companies cover genetic testing. If an insurance company does not, Foundation Fighting Blindness, in partnership with Blueprint Genetics and InformedDNA®, offers an open access, no-cost genetic testing program called the My Retina Tracker Program® starting October 21st for individuals living in the United States, with a clinical diagnosis of an inherited retinal degeneration (IRD).
