RETINA E-News: Dis-chem ride for sight 2018

Winners of the Dis-Chem Ride for Sight Super Classic include Reynard Butler.

Finding treatments for retinal blinding conditions such as Retinitis Pigmentosa, Macular Degeneration, Macular Dystrophies and allied retinal conditions.

The 30th edition of the Ride for Sight was held on Sunday 18th February 2018. This premier road cycling event was sponsored by Dis-Chem Pharmacies and the City of Ekurhuleni hosted the event. This tremendous support and sponsorship ensures the continued success of this – our premier fund raising event. This was the 30th Anniversary of the event which has raised over R10M for research in South Africa. The Ride is managed and manned mostly by volunteers and we are indebted to all our supporters- and most of all the dedicated cyclists who once again cycled to restore the gift of sight. All the proceeds go directly to our RD Project at the University of Cape Town. In spite of the decreasing numbers at many cycling events we were able to maintain a field of over 5000 cyclists. Dis-Chem Pharmacies and the Dis-Chem Foundation once again gave us wonderful financial as well as marketing support. The support from Ekurhuleni Departments of Sport, Recreation and Marketing was outstanding and this unique partnership of an NPO, Corporate, local Government and Community organisations proves what can be done when we all work together.

The Ride also supports cycling teams who are working to develop the sport in the community. The East Rand Cycling team pictured right with Claudette Medefindt have shown amazing growth and this year had 32 riders with three team members cycling in the Elite and under 23 category with the cream of SA cyclists. Other teams who were supported are the

RESEARCH NEWS: GENE THERAPY REGISTERED

The first ever gene therapy for Inherited Retinal Disorders [IRD], brought to market by Spark Therapeutics, was approved by the FDA in December. Although this will only treat patients with Leber Congenital Amaurosis [LCA] and early onset Retinitis Pigmentosa [RP] who have a confirmed RPE65 gene mutation, it is a magnificent first step to ensuring therapy for all. The price is prohibitive and unfortunately beyond reach of most patients. NOVARTIS has been licensed to market the therapy outside of the USA. Jack Hogan, a 13 year old from New Jersey, USA was the first commercial patient to receive the therapy, Luxturna at the end of March. Spark has set up a fund to refund patients if the therapy is unsuccessful.

STEM CELL THERAPY FOR WET AMD

2 Patients in the UK with Wet Age Related Macular Degeneration [AMD] recently received new Retinal Pigment Epithelial [RPE] cells grown from Stem cells. Researchers at the University of California, Santa Barbara, engineered a retinal patch from human embryonic stem cells that were matured into RPE cells, the nurse layer of cells that underlie the Photoreceptors. In both AMD and Stargardt Disease, it is in this RPE layer, that the degenerative process first begins. The patch is then implanted under the retina to replace the damaged RPE cells. A delighted Douglas Waters, 86 years old , was one of the patients to receive the therapy. He could barely see before the therapy and is now reading a book. Dr Peter Coffy study author said “We can stop people from going blind”. The trial will continue with 8 more patients. See this link

USHER SYNDROME

Cochlear Implants [CI] to restore hearing in Usher patients was until recently thought to only be successful in young patients. A recent report has debunked this theory and has shown successful CI in Usher 2a patients with a mean age of 59 years. A team in France has shown that Cone degeneration in Usher Type 1 patients is triggered by the absence of USH1 proteins but prevented by antioxidant treatments in mouse models of the disease.

And for the more scientific minded here is a cool animation from Nature.com that shows how it works and the unlimited potential of this exciting research.

PIXIUM ARTIFICIAL RETINA

PRIMA, a miniaturized wireless photovoltaic sub-retinal implant, has successfully been implanted into a patient with Atrophic Dry-AMD. PRIMA is a miniaturized new generation totally wireless sub-retinal implant, a micro photovoltaic chip of 2×2 millimeters and 30 microns thick, and is equipped with 378 electrodes. Implanted under the retina via a less invasive surgical procedure, it acts like a tiny solar panel that is powered by pulsed near infrared light through a miniaturized projector integrated into a pair of glasses along with a mini-camera, worn by the patient. [ yes, very technical but so is the chip.] See: www.pixium-vision.com

NEW ANTIOXIDANT UNDER INVESTIGATION

The Foundation Fighting Blindness, USA, has announced that they are supporting research to investigate N-acetylcysteine-amide, [NACA) an antioxidant that may slow the rate of degeneration in many forms of RP. They will invest up to $7.5 million to advance the potential therapy into and through a Phase II clinical trial. In several animal models, including previous FFB-funded lab studies of rodent models at Johns Hopkins University, NACA slowed retinal degeneration. The drug is designed to slow vision loss by protecting retinal cells from oxidative stress, a process that accelerates degeneration in many inherited retinal conditions including RP. When the cells in the body process oxygen, they produce byproducts known as free radicals, which can be harmful if the body is unable to neutralize them. In certain diseases and conditions, cells have a difficult time neutralizing free radicals, and damage occurs.

Patricia Zilliox, PhD, chief drug development officer at FFB-CRI, said “Oxidative stress causes cell degeneration and vision loss in virtually all forms of RP, so we are hopeful that NACA, with its anti-oxidative properties, can benefit most people with RP, regardless of the gene mutation causing their disease.”

SO WHAT ABOUT ME?

The most common questions posed to Retina South Africa are: How can I get into a clinical trial? Why is therapy taking so long? Stem cell and other therapies are advertised on the internet – should I try them?

Clinical trials are strictly controlled and take years to complete the 3 phases. Phase 1 and 2 involve small numbers of patients who live close to the clinic for regular monitoring. These 2 Phases test safety and sometimes different dosage levels. Once successful they then move to phase 3 with larger numbers of patients. Retina South Africa is in discussion with a number of trial organisers in an effort to bring multi- center phase 3 clinical trials to South Africa where our patients could be eligible for participation. Patients need to ensure that they are registered with Retina South Africa, have a genetic test result that is lodged with Retina South Africa and have regular eye examinations with their Ophthalmologist.

Clinical trials are strictly monitored to ensure your safety. The RPE65 Gene therapy, that has just been registered, took ten years from the first patient tested to registration. We know that this success will speed up the process for other future trials. We understand your frustration, but do not be lured by unscrupulous charlatans peddling so called “cures”. Ask for results of clinical trials published in reputable scientific journals. Discuss with your Ophthalmologist or contact Retina South Africa. Treatments are on the way, so don’t risk losing your remaining vision to risky and unproven interventions.

RETINA INTERNATIONAL CONGRESS

  

The Retina 2018 World Congress was held in Auckland, New Zealand from the 7th to 11th February 2018. The majority of the speakers were from New Zealand and Australia and the quality of the presentations was extremely high. The highlight of the congress for Claudette was meeting with two of the most eminent researchers from the USA – Prof Jean Bennett who perfected the RPE65 gene therapy, and Prof Eric Pierce who is doing amazing research into stem cell therapy for IRD, pictured right at the congress with Claudette Medefindt. Key note speakers who are renowned internationally and have both visited South Africa were Gerry Chader and Elise Heon. Both gave superb presentations in their informative and easy to understand style.

Pictured left are Claudette Medefindt, with Christina Fasser center, President of RI and Prof Elise Heon of Sick Kids Hospital, Toronto, right. Pictured at the Gala dinner on the right were Claudette Medefindt and Avril Daly [back], the new dynamic CEO of Retina International with Carla and Gerry Chader in front. Claudette represented Retina South Africa at the congress and has now retired as Deputy President of RI but remains on the Management Committee in an advisory capacity. The next RI congress will be held in Iceland in 2020 and this promises to be exceptional in every way. Start saving now !!

SENSIBLE EATING

The damaging effect of oxidative stress is a modifiable risk factor in retinal disorders. So eating a diet rich in antioxidants is an easy way to slow the rate of degeneration. Colorful fruits and vegetables are high in antioxidants and oily fish is high in Omega 3 fatty acids -also known to slow retinal degeneration. One of the most important antioxidants for retinal health are Lutein and Zeaxanthin, found in green leafy vegetables. Avoid all synthetic food additives and artificial flavorings, colorings and sweeteners. Eat fast foods very sparingly and maintain a healthy gut microbiome. A simple Eating guide is available from Retina South Africa. Discuss supplements with you eye specialist – Ocuvite for AMD, Retina Plus for RP or Macula plus for Stargardt Disease and Cone Rod Dystrophy. If you have any early onset central vision loss you must NOT take any supplements containing Vitamin A or Beta-carotene. Smoking is the worst thing you can do to your vision while moderate, regular exercise is very necessary.

Various Retina organisations, including Retina South Africa tested the app in the development stage.

E SIGHT

This amazing vison enhancing device was demonstrated at the National meeting of Retina South Africa on 13th April. The device is reminiscent of the fictitious one seen in Star Trek, but works. Those with central vision loss such as Stargardt Disease or Dry AMD would appear to benefit more. Manny Moodley, Western Cape Chair and a busy lawyer was especially impressed. It does not help with mobility or driving but is excellent at helping you see static objects- presentations, blackboards, faces etc. You can use it for TV viewing but not for fast moving sports programs. It has a field of 37.5 ̊ and magnification from x2 to x24. It is recommended for people with a visual acuity from 6/24 to 6/240. It has OCR and freeze capabilities with an SD card and can read Pdf documents. It is a truly amazing device and the only drawback is the price – around US$10 000.
