[net.med] floater followup

tiberio (01/20/83)

protein floaters are large protein molecules in the fluid in your eye.
the best way to see them is to look into a blue sky and move your
eyes from side to side, they follow the currents you set up in the fluid by
accelerating and decelerating the eye.

when i mentioned vdt's in my previous submission i meant to include
things like the tek 4014 (vector storage scope), megatek 7000 (vector
refresh scope) and the megatek 7250 (raster refresh scope) which i use.

i mentioned facial rashes not because i have any but because some
scandinavian study found a link. i figure we have a large population of
users and some trends might show up if people simply look for them.

According to my recollection (correct me gently if I am wrong) of an
"Amateur Scientist" column in Scientific American recently, the
floaters in the eye are usually gobs or chains of red blood cells
that have escaped into the interior of the eye.  A single red blood
cell would be too small to notice, so I don't think a mere protein
molecule (or chain of them) would be noticable.

Floaters are more noticeable if you are nearsighted so I have been told and
also seem to be more prevelant in the eyes of nearsighted people.  I first
noticed them during a bright sunny with 2 feet of snow on the ground.  People
thought I was nuts when I said I could see these spots moving around.  That
was in 1969 when I was 18 years old and they have been getting worse since.
Most of the time I don't notice them or pay attention to them but I wish there
was a way to get rid of them!

I have had floaters for most of my life.  Usually they don't bother me
but I can recall one time in high school that I couldn't read because
they were blocking my vision to a great extent.  One side effect of this
discussion is that I think about floaters more and thus notice them more
which means I am distracted by them more.

Wow!!  I thought I was crazy when I saw these things floating around in my
field of vision!  I thought that maybe they were dust particles on the surface
of my eye; my conclusion was based on the observation that I could make them
float around (move in my field of vision) by blinking quickly.  So these things
are really *inside* my eye?  Hmmm, do they just get worse with age?  Do they
`disolve' eventually?

with age.
