Anyone else ever even heard of this? Any info would be appreciated.Peace to you.
Your friend is describing vitreous floaters.
The eye is a hollow structure, and most of its volume is filled with a "jelly" which approximates the appearance and consistency of raw egg whites.
In childhood, the vitreous tends to be more uniform, and is firmly adherent to the sides of the eye.
As we age, the vitreous tends to contract and get stringy. The little irregularities and debris that appear can bend or scatter light, and cause the floaters that most of us see when we look at a featureless light background, like a blue sky or white ceiling. Eye movements will stir up the vitreous and make the floaters move around some, but they'll typically stay in the same region of the visual field. Many patients note that if they try to look directly at a floater, it will seem to dart away.
As this process progresses, the bulk of the vitreous may completely detach from the eye wall (a posterior vitreous detachment). This may cause a sudden and fairly dramatic increase in floaters, and the new floaters may be very impressive because the are close to the retina and therefore in relatively sharp focus. This happens more often, at an earlier age, and more impressively in nearsighted people.
The vitreous detachment by itself is annoying but benign. The problem is that occasionally it remains firmly enough attached to part of the retina to pull a tear in the retina itself, which can lead to a retinal detachment.
I see about 2-3 people a week in my practice with new onset floaters, and will dilate them to look carefully in the periphery of the eye for retinal tears. I usually see them back about six weeks later to recheck, because the risk remains elevated for a few weeks.
Patients are often told they will go away, but that's not really true. What happens is that they may sink lower in the eye (out of your central vision) or that you just get used to them.
Hope this helps.
