My Floaters Are Gone. Long Live My Floaters?
"Jan Owen" wrote in message news:J8i_a.78095$zy.4412@fed1read06... Hi, Al, Be VERY careful about this. Sudden onset of, or an increase in, floaters can be a sign of an impending detached retina. Jan, Thank you for your concern. I went to the doctor the very first day I noticed my floaters. My doctor was also concerned about the possibility of a detached retina, and for this reason examined me 3 times in the first month. He now tells me that there is a much reduced possibility that the floaters could lead to a detached retina. It seems that my problem is simply floaters (thank the lord!). I can speak to this, as I had one a couple years ago, and it was NOT a fun experience. The surgery was an amazing experience all in itself, but not one I ever want to go through again. Could easily have lost the sight in my right eye, but instead, after surgery, my corrected vision is once again 20/20 in both eyes, and on a good day, can be 20/15 combined, though it seems more often to be closer to 20/20... WHEW!!! Happy your story has a happy ending. But the bad news is that I now have LOTS of floaters in my right (eyepiece) eye. It's still not a big problem until I dial the power up, but once the exit pupil gets small, the floaters become quite pronounced... My floaters have not been too much of a problem at the telescope. The reason for this is that I got the floaters about 5 months ago and only used a telescope about 6 times during that period (4 times during the day for solar viewing and twice at night). These 6 times at the telescope were the ONLY opportunities I had because the rest of the time it was either cloudy or raining...no kidding! Al Good luck! |

Aqueous or vitreous? Howard Lester I'm not sure... here is a drawing of my floaters, I made this in late 1999, when they were brand new and at their worst. Drawing: http://www.eagleriver.com/floaters.jpg What happened? I had an ultra hot and bright camera flash go off about 10 inches from my eyes, at a time when I had a very intense flu. About 1 month later.. here came these floaters, for the first time in my life. I believe it was the camera flash heat on my retina more than anything. Curiously, since the last four years, these floaters have diminished by 80% perhaps. I hope I'll get to "95% better" in another 4 years. For people who like to fixate on their medical problems, you could sell Radian 3's as "Floater Viewers". I find the most effective method of examining ones floaters is to take a Radian 3 (out of a telescope) and look through it with a light source behind it. Bright skies are another easy way to see them, as my drawing indicates. Also, if I take my 4 diopter glasses off and look at christmas trees, all the lights go wild as they are affected by floaters. Since I had total clear vision before 1999, floaters disturbed me very much for a good year. Eventually I got used to them flying around. I still have "bad days" and I wonder if it has to do with things like dehydration, etc. Mike C |

Other than the fact most people never look at anything thru an eyepiece at high magnification.... Orion "Fred Ma" wrote in message ... P.S. The astronomer's reasons are not much different from other people's reasons for wanting to get rid of floaters. Fred I'm sure a floater is equally distracting whether it obfuscates the stars or a view of an integrated chip, either in a microscope or on a computer screen. Or looking at instrumentation like oscilloscopes and spectrum/network/logic analyzers. Or looking at presentations projected on a screen. It totally ruins efforts at trying to rapidly read many technical papers, and composing/reviewing/revising papers can be quite frustrating. Most, if not all, of what I've read on this thread is applicable to astronomers and nonastronomers alike. Fred (posting on the bottom) |

It is therefore less of an issue for unaided-eye observations, like a presentation on a screen, or viewing a computer monitor. Brian, it is apparent you do not "suffer" from floaters. I recently had vitreous separation (in both eyes, over a three month period!). The resultant floaters make reading a book or text on a 17" LCD monitor unpleasant. Damn good thing I'm retired, because I sincerely doubt I could function in the workplace well enough to keep my job. In discussing this with various eye docs, and fellow "sufferers," I find my experience to be pretty typical. Not that it changes things, but at least I am not alone in this. I am not retired, just finishing up a Ph.D. in fact. I can say it is many,many times more energy draining to read deeply and critically when the floaters act up. I've been single mindedly focusing on finishing, but many times, I wonder what were my options afterward. Most pages are white, so pupils are small. Most document preparation software these days insist on having a white background. Besides that, choice of documentation software is driven by functionality rather than color of background. Furthermore, most labs are shared, and well lit, again leaving pupils small, and floaters very noticable. I wonder what kind of pressure or lobbying it takes to funnel funds into research to find solutions to floaters. Technically, the problem seems simple. I wonder why there hasn't been more work on the vitreous to see what can make it stay nice and uniformly fluid or gel-like, and expanded. Or why cataracts develops when it is replaced. Supposedly, there are a host of complications besides cataracts. My semi-communicative eye specialist gave chilling descriptions of having rubber bands around one's eyeball (can't remember exactly why). As well, fixes for the cataracts supposedly leave the lense on the eye irresponsive. No explanation why, even though the muscles attached to the lense are still present. As for laser blasing the floaters, the shock wave potentially causes retinal detachment. Never a good thing, since fixes for retinal detachment don't always leave the best vision. Then again, we have problems like AIDS, SARs, cancer, diabetis, etc.. So I guess I understand why funding for vitreous is not overwhelming. Fred |

If you have the luxury of preparing your documents on Windows machines, most software will observe the rules of the display scheme you define. Word, FrameMaker, Mathematica, and other such will happily operate with light colored fonts on a dark background. Outside of the Windows environment, at least some programs support individual control of color preferences. And this does greatly reduce the impact of floaters. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |
