July 2018 Update - Visual Snow

Visual Snow Research – Where we were, where we are and where we are going

 

No matter if you have a mild case, or a severe case, Visual Snow is probably never far from your mind. It is definitely not a condition that is easy to escape because we see it everywhere. If you are like me, you want research to move faster and have more information coming in. Trust me, I feel you! It’s so hard waiting and waiting days, months and years.

 

Here is what we know right now:

For the current MRI study being conducted in London the doctors have scanned 15 patients and 12 controls.

 

As far as the diary/questionnaire study there have been 1100 patients contacted and asked to participate, and only 150 have returned the information asked for. This phase of research has taken a back burner to the MRI at this point. If you are still interested in participating, they are still taking applicants, but it may take some time to receive a response back from the doctors. You can find information on how to apply at http://www.eyeonvision.org

 

What does the near future hold for research?

 

Dr. Puledda, Prof. Goadsby and team are moving forward with a study involving genetics and cerebrospinal fluid analysis for visual snow but are still waiting for ethics approval for that. It took a very long time to receive approval for the last phase of research, so we are in a wait and see period.

 

What can you do to help?

 

Currently visual snow test subjects have been coming from the London, England area, so if you are in that area, you can play a crucial part to the research, potentially. Please reach out to me, Jen Ambrose, if you would like to be in touch with the doctors and are in or near London.

 

If you are out of the area, we are looking for financial support to help continue the research. Medical research in expensive and lengthy, and Eye on Vision Foundation has done it’s best to support the research, but funds have dwindled greatly over the past few years, and this has caused delays in research. The more doctors assigned to the research the faster it will move for us. Donations can be made on a one-time or a monthly basis through http://www.eyeonvision.org. You will see a PayPal link. Remember that this is a tax-deductible donation as we are a non-profit. All donations will go straight to the research. There is no overhead for Eye On Vision, so all monies are donated to the research.



 
Update on VS Study

Hello Visual Snow and Eye on Vision Supporters, 

Patients are actively being recruited for the imaging study and three subjects have completed it to date.

The questionnaire study has received several responses back, but not nearly the amount of responses back that we need. Please, when you receive the request to complete the diary, please complete and send back via the instructions. The first questionnaire that you send back is only part one. When the doctors write you back, they will need you to complete part two and send that back as well. I will include part one here again for those who have not completed this yet.

    Explanation of VS study in Germany



    Many of our donors have asked for a little more explanation of what the German visual snow study was looking for, which we helped to fund in 2014. I recently wrote to Dr. Schankin and this was his reply:


    With that study, we investigated the processing of basic visual information in the brain of patients with visual snow. The aim was to see if we can find objective electrophysiologic data for the condition that might serve as measures for future treatment studies. This is important since - in contrast to radioactive brain imaging that we did before – these tests can be repeated.

     

    The results of this study need to be reviewed during the meeting and by colleagues before any clinical application can be designed. 


    It is Dr. Schankin's hope that colleagues will be able to look at the data this coming September. 


    While every part of Visual Snow research is crucial to better understand this condition, we are still in the very early phases of research. More financial support is needed in order to continue through the necessary phases of medical research. Please consider supporting us today. We still need almost $50,000 more to ensure that Dr. Puledda's salary is covered for another year. Without this money the research will have no funding to continue. 



     
    VS testing to begin in London in May 2017


    I'm sorry that there was such a long delay in hearing from me, but I sustained an eye injury in Feb and am only recently returning to limited computer use. 

    I do have an update from London to share with you. Patients have begun to be qualified and scheduled for testing. Scans are scheduled for May and June at King's College. This is an important phase of research, because what is learned from these scans will determine how we enter into a treatment phase of research. Without this phase of research, we will not be able to proceed to medication testing. With that being said, I've been approached about funding for Dr. Puledda's salary for another year. Dr. Puledda works under Prof. Goadsby and is the primary doctor assigned to the Visual Snow research at King's college. As stated in previous updates we need approximately $70,000 USD per year to employ her. Currently we have only raised $20,000 USD which is a far off sum from what is actually needed to secure her. 

    Almost all of you reading this who have VS have likely undergone an MRI. You have likely seen the very high bill to your insurance, or you have paid out of pocket. It's not uncommon to see bills over $1000. We are very fortunate that King's College covers all of these costs towards VS research. We need to assist them though by being able to pay Dr. Puledda for her time and efforts on our behalf. 

    We would love for you to become a monthly donor and help us achieve our research funding goals. You can sign-up as a monthly donor here:

    Research to begin in London

    Patients have begun to be recruited for the imaging study in London, England. Within the next two months we hope to see the first patients being scanned for the MRI study.   Continued funding is asked for as we are just in the beginning phases or research and want very much to see it continue. It costs almost $80,000 USD per year to employ one research doctor. We would love for you to become a monthly donor and help us achieve our research funding goals. You can sign-up as a monthly donor here:
