Update on VS Study PDF Print E-mail

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.
