Dear Sufferers,

Recently Dr. Sebag released a brief interview with some important updates for the VDM PROJECT.

The VMR RESEARCH FOUNDATION, along with prominent partners and doctors, is working to make progress and get closer to a better solution to diagnose and treat eye floaters.

In this interview, Dr. Sebag answered some of the most relevant questions from the community and shared some significant considerations on the recognition of VDM as a significant disease by medical practitioners vs. being considered simply a nuisance.

In the upcoming months, we plan to involve doctors and experts from the Scientific Advisory Board to begin discussing different points of view and possible solutions to cope, treat and cure eye floaters.

 We have uploaded the video of Dr. Sebag’s interview to the VDM PROJECT YouTube account.

Since inception, the VMR Research Foundation (VMRR) has built upon vitreous R&D begun by Dr. Sebag in 1978 at the College of Physicians & Surgeon, Columbia University and continued at Harvard Medical School from 1980 to 1986. This work has since produced over 250 academic publications in peer-reviewed publications top journals, as well as chapters, books, editorials, reviews, and letters. Dr. Sebag has delivered 253 lectures and presentations throughout the world. In addition to defining the roles of vitreous in ocular health and vitreo-retinal diseases, VMRR has focused on the problem of Vision Degrading Myodesopsia (clinically significant vitreous floaters). To address the unmet need for better understanding and new treatments, VMRR is undertaking several ambitious projects.


A. VDM Project (www.VDMresearch.org)

Educating the public and raising awareness (as well as funds) have been prime objectives of the VDM Project. A scientific advisory board was assembled consisting of Professor Taiji Sakamoto (Japan), Professor Alfredo Sadun (Los Angeles), Professor Paulo Stanga (London), Professor Susanne Binder (Vienna), and Dr. Felix Sauvage (Belgium). Quarterly meetings have been held with the leadership of the VDM Project. Public awareness and education are cornerstones of this endeavor.

Eye Floaters Prevalence Study

Eye Floater Prevalence Study

The VDM Project is currently in the process of commissioning a study on the prevalence of vitreous floaters among adults in the United States.

Although the survey instrument will not be administered in a clinical setting and will therefore not allow for patients to undergo the objective testing that could be used to establish a formal diagnosis of vision-degrading myodesopsia, its purpose is nevertheless to ascertain just how many individuals are afflicted by floaters and how many report that their floaters are serious enough to affect their daily activities and quality of life. 

Existing research on this question suffers from clear problems of selection bias [1], and so the VDM Project will be working with a company experienced in collecting data for social scientific studies to ensure a representative sample that allows for valid statistical inference.

Although ophthalmologists (and retina specialists in particular) anecdotally report that floaters are very common, especially among older adults, these reports somewhat paradoxically seem to coexist with a widespread perception among clinicians that disability resulting from floaters is very rare, if it even occurs at all [2].


Some authors have even expressed surprise that studies of vitrectomy for the treatment of floaters have been able to find enough patients whose condition was serious enough to warrant surgical intervention [3].

This new prevalence study will finally provide vital data that has long been lacking on the societal impact of vitreous floaters.

Even for many other conditions that are comparatively understudied, such as tinnitus [4], fibromyalgia [5], or myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) [6], there at least exist credible estimates of population prevalence. 
These estimates will be critically important in helping us to convince government and industry to devote desperately needed funding to develop better and safer cures.
Please support the VDM PROJECT to help us find a safer and better cure for Eye Floaters

Research Update: January 2021

Dear VDM Project supporters,

As 2021 begins, we are continuing our fight to find a safe and effective cure for Vision Degrading Myodesopsia (Eye Floaters). As our team grows, we are uniting more sufferers and becoming a stronger force for change.

We have three exciting updates to share with you:

1) Dr. Sebag Publication:
“Vitreous and Vision Degrading Myodesopsia”

Importantly, Dr. Sebag continues to work tirelessly to have Vision Degrading Myodesopsia (eye floaters) recognized as a disease within the medical community – this is no easy task. By having this classified as a widespread problem for many people around the world, it will open the door to greater funding and research opportunities toward a cure.

Over the last two years, Dr. Sebag has authored a major article named ‘Vitreous and Vision Degrading Myodesopsia’, now published in the most prestigious journal within the eye world.

Why is this important? Because this major article shows that we are changing attitudes – Vision Degrading Myodesopsia is being classified as a disease that can impact the lives of sufferers dramatically. This article is the first of its kind and is helping the voice of eye floater sufferers become heard.

As we continue to raise more awareness and change opinions of the medical world, this will lead to more funding opportunities to expand on clinical research.

Please join us in thanking Dr. Sebag for dedicating two years to this work and congratulating him on this enormous achievement. This shows the great progress he is making within the medical world and takes us a large step closer to a floater-free future for all.

2) Dr. Sebag: Research Updates

Although we are crowdfunding to support this initial research, our key aim is to receive governmental and/or institutional funding which will allow this clinical research to take place – meaning a safer cure can be found sooner.

The below summary from Dr. Sebag outlines the projects he has been working on, and the funding he has applied for. If successful, this funding will be a key step in our fight for a cure:

Better Understanding

To better understand how vitreous causes Vision Degrading Myodesopsia (VDM), specimens removed during vitrectomy surgery for advanced cases are being studied at the Huntington Memorial Research Institute in Pasadena, California and the University of Ghent School of Pharmaceutical Sciences in Belgium.

Clinical studies on vitreous following posterior vitreous detachment (the most common cause of floaters) will be completed and published.

Clinical studies on the role of crystalline lens status on VDM will be completed and submitted for publication. This will help us understand that in certain patients vitreous induces additive effects to degrade contrast sensitivity function and that these deleterious effects can be eliminated with limited vitrectomy, improving vision and quality-of-life.

Clinical studies on the impact of myopic vitreopathy on VDM have been completed and will be published in 2021.

Better Diagnostics

A grant proposal has been submitted to the European Union to develop better imaging of vitreous with the aim to enhance diagnostic evaluation of floater sufferers.

A second grant proposal was submitted to the Polish Ministry of Health to develop better optical imaging of the human vitreous body.

A third grant proposal was submitted to an ophthalmic technology company to improve acoustic imaging (ultrasonography) of the human vitreous body.

A self-administered questionnaire will be finalized to screen large populations as well as evaluate a single individual so as to assess the impact of floaters on vision (subjectively) and quality-of-life.

Testing paradigms of the speed and accuracy of reading will be developed and implemented to better evaluate the impact of vitreous on vision and visual function in daily living.

Better Therapeutics

A grant proposal was submitted to a laser technology company to evaluate and improve YAG laser vitreolysis.

Novel nanotechnology-based treatments are currently being tested for safety in animals and will be developed for human trials.

A project will be launched to evaluate and refine the use of pharmacologic pupil dilation to lessen the severity of the disturbing visual phenomenon of floaters.

3) Fundraising: $20,000 milestone

We are incredibly grateful to all supporters for their trust and belief in this movement. Thank you to the 134 contributors who have donated to clinical research – every amount directly supporters research toward a safer cure for eye floaters.

We would like to extend our sincerest gratitude to The Weatherstone Family Foundation, Inc. for their generous support of $15,000 between December 2020 and January 2021. We cannot thank you enough and your contributions will always be remembered.

As we continue grow, now more than ever we need dedicated, committed and ambitious people to help us – as we can only achieve so much alone. If you would like to apply to the VDM Project to fight for a cure with us, you can do so here.

Thank you for your continued belief, and we are more positive about the future than we ever have been,
Your VDM Team
