Dear EURETINA Members,

 

A very warm welcome to the November 1st, 2016 edition of EURETINA’s web-based digital magazine, “EURETINA Brief”. EURETINA are delighted to continue our delivery of up-to-date summary briefs on a range of topics of interest to retinal clinicians, specialists and researchers across Europe. This resource is designed to accommodate the very busy schedules of all our members by providing them with a short overview of some new developments and announcements in our field over recent weeks.

 

As in previous issues we have incorporated a feedback section where you can comment on any of the news items or articles under discussion and we very much welcome all contributions. Previous articles and issues can be found in the archive section on this website.

 

The current issue highlights a number of research activities, clinical/regulatory milestones and business developments in our field, including studies by the University of Pisa suggesting that neural plasticity in the brain may benefit from prolonged use of a retinal prosthetic device; a report on a multi-center, double masked phase 2 clinical trial showing that a small protein therapy targeting diabetic macular edema patients may be comparable to monthly treatments of ranibizumab, and; an announcement from GenSight Biologics S.A. (Euronext: SIGHT) on their receipt of Orphan Drug Designation in Europe for an experimental retinitis pigmentosa (RP) treatment, “GS030”. According to the company, GS030, is an optogenetic therapy delivered using adeno-associated viral (AAV) vectors to introduce the genetic sequence of a photosensitive protein into the nucleus of target cells.

 

Finally, our feature bio-ophthalmology article reports on the recent genomics success in uncovering 52 independently associated common and rare variants for wet and dry age-related macular degeneration (AMD) distributed across 34 loci. The research, conducted by the International AMD Genomics Consortium (IAMDGC), reports an almost doubling in the number of genetic risk loci associated with AMD. In the significant research paper published in the journal Nature Genetics, the consortium details an analysis of >12 million gene variants, “including 163,714 directly genotyped, mostly rare, protein-altering variants”. The study, which included 16,144 patients and 17,832 controls, resulted in the identification of independently associated common and rare variants (P < 5X10^−8). In addition, the consortium claims to have identified the first genetic association specific to wet AMD, a locus close to the matrix metalloproteinase gene, MMP9, (difference P value = 4.1X 10^−10).

 

As always, increased interaction by you with the EURETINA web community serves to expand your professional network and keep you up to date with the latest initiatives, activities and research in your field. Our hope is that such cross-fertilisation in an active web-based platform, including our LinkedIn page, will lead to increased collaborative opportunities and ultimately to improved patient care. All readers are invited to submit comments or responses to any of the stories featured and we look forward to hearing from you over the coming month.

 

Best wishes,

 

Dr. Gearóid Tuohy, EURETINA
