Default My Floaters Are Gone. Long Live My Floaters?

I have floaters and have had them for a few years now. Mine look like
multi-celled single-strand organisms and move in and out of my field of
view. I can see them at high powers when using a telescope but not all the
time. I did some research on the net an found this site:

Apparently, The FDA considers the procedure a non-risk issue.

I must have been about five-years old when I first became aware of my
floaters. We had a chandelier in our foyer and if I squinted my eyes

Anyway and more seriously, any patients of Dr. Karickhoff lurking here?


No, but I was a patient of Dr. Hackenbush.

Floaters never just "go away"...



I don't think this is universally true. Floaters have different sources, and
their lifetime in the eye varies. Floaters caused by polymerization or
crystallization of vitreous have low mobility, and may indeed remain in the
posterior chamber for a lifetime. But cellular debris has higher mobility, and
can be transported through or around the vitreous body to the anterior chamber
over a period of months to years. Material smaller than about 10u can cross the
trabecular network and leave the eye. As you know, small hemorrhages into the
vitreous can be cleared from the eye over time, and large hemorrhages can result
in glaucoma because erythrocytes/ghost cells interfere with the trabecular
meshwork.

And of course, floaters with some mobility may be carried out of the optical
path in the eye. That's pretty close to "going away." Even if the material is
still in the eye, I don't know if you could really call it a floater if it can't
be seen.

More often than not I see floaters in nearly 100% of my adult patients
and they do not complain of them.
Guess it depends on what your definition of "is" is. "Floaters" as an
ophthalmological phenomenon however usually specifically refers to
aggregates of denatured proteins. Vitreous hemorrhages and the like are
separate entities, but unfortunately too many EyeM.D.'s refer to the
symptoms as floaters. Ghost cell glaucoma is fortunately rare and an
intact zonular system(the microfibrils that attach to the capsule that
contains the lens) prevents anything much larger than single cells from
entering the anterior chamber, to gain access to the trabeculum. Often
floaters become sequestered within the vitreous, out of the line of
vision, but they nonetheless remain within the eye.


the brain selectively perceives that
they are no longer there.(Consider the physiologic blind spot where the
optic nerve enters the back of the globe...nobody sees their blind spot
but it is nonetheless there.)



That isn't my own experience. I've had a few irritating floaters for many years,
and I've never gotten used to them. The low-level cortical response to movement
is very strong- I don't see how you can get used to something that produces the
appearance of movement, especially across the fovea.

I certainly won't tell you what you experience. Each patient's mileage
may vary. I routinely tell patients that there is a good chance that
within a year, they will not notice the floaters, except under
conditions that cause miosis(small pupils). For me, it's a truism 90%
of the time.

Skip

As far as your eyes go.. Go see a qualifed practioner about this.
Youre eyesight is too valuable to speculate on. You may have already
done so.

For the past 6 months or so, I've had a couple of thin, thread-like
floaters in each eye but today I can't seem to find them. Do these
things ever disappear of their own accord via some sort of
disintegration process? If they come back, can an eye doctor safely
remove them?

I have a bunch of permanent floaters from a tiny fall off a cliff awhile
back, while doing some wild abandon skiing.

When I asked, the eye doc told me: No, they can't be removed. I assume
he really meant: No, you can't afford whatever procedure is used to
remove them.

No, I think he meant they can't be removed. At least through surgery.
I suppose they could drain each eye, fliter them out and replace the
fluid. But this type of procedure has, to my knowledge, never been
attempted.

Since I mostly do planet observing at 1mm exit pupil, I have been quite
aware of my floaters for years. In my observing eye (left) one round floater
has become either more compact or closer to the retina. It used to appear
like a single celled organism in a microscope, now it is JUST the right size
and darkness to look like a dark spot on Jupiter about the size of a Jovian
moon shadow.

It also is quite noticeable in the daytime because of (as you noted) the
motion. I have been known to swat at "invisible" insects flying near my
head. :-)

I have (mostly) trained myself to wait for the SOUND of a flying insect
before I start flailing.

Clear Skies,
Craig in Tampa

Sounds great for those with the type(s) of floater(s) that can be
reduced/eliminated by the procedure, but results appear to be quite variable
and procedure not applicable for many. Check out "Floater Types-Success" in
the menu on the left side of the web page that you hyperlinked.

How does one discern? I didn't realize that
the treatment prospects were different for
different kinds of floaters. The only two
treatments are frought with nasty risks.
The specialist I saw doesn't
think it's a good idea to change the
eyeball fluid, or the explode the floaters
with a laser.

What I wrote was a joke... The liquids within the eye are known as
"humors." You had set me up perfectly for that one.
