The vitreous is a clear, gel-like substance that fills the space in the middle of your eye. It’s mostly made of water, with supportive molecules like collagen and hyaluronan that help it stay smooth and transparent.
Over time, or with conditions like nearsightedness (myopia), changes can happen in this gel. The collagen and hyaluronan separate, and the collagen clumps together into tiny strands. These strands float in the gel and cast shadows on the retina, which we see as floaters.
As we get older, the gel naturally starts to break down and shrink. This can cause it to pull away from the back of the eye — a process called posterior vitreous detachment (PVD) — which is the most common cause of noticeable floaters.
Recent research shows that floaters are not only very common, but they can also significantly affect a person’s quality of life, more than doctors used to think.
Currently, doctors manage floaters in a few ways:
Watch and wait (most floaters fade or become less bothersome)
Vitrectomy surgery, which removes the vitreous gel — this has a high success rate and low risk when done with modern, small tools
Laser treatment (YAG laser), which tries to break up floaters — but the success of this varies widely and isn’t as well supported by research
So far, vitrectomy is the only treatment proven to work. More research using clear, measurable tests is needed to compare these options and to see if new treatments — like medications that dissolve floaters — could be effective and safe.
