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

It is somewhat surprising, however, that hundreds of patients presenting to these centers, over a short time period, would be impaired to the extent that PPV is required”)
