Video: Asteroid Hyalosis

Last updated December 29, 2007


length: 43 seconds

Asteroid hyalosis describes white floaters in the vitreous humor of the eye. These bodies are different than the typical floater, and usually don’t cause visual disturbances. They are caused by calcium soap deposits and can be associated diabetes, hypertension, and high cholesterol.

Though usually visually benign, these rarely cause significant visual disturbance. The opacity usually affects the view into the eye more than the patient’s view outward, such that a vitrectomy may be required if more serious retinal disease exists that needs to be treated/watched by the ophthalmologist.

- Occurs twice as often in men than woman
- Usually found in people over 60 years of age

I started seeing a floater with my left eye in November 2007. I went to an ophthalmologist who told me I had vitreous detachment (eye floater). I had never heard of eye floaters before. He basically told me there was no cure for eye floaters and that I would eventually get used to it and it would become less noticeable. Well, I knew there was no way I would get used to that, since I use computers all the time and I’m an avid reader. I then did some research online and came across an NBC article about Dr. XYZ (removed by editor), who treats eye floaters with laser. Dr. XYZ happens to be 30 minutes from where I live, so I decided to give it a try and see what he would say about my case. After checking my left eye, Dr. XYZ determined that my floater would be difficult to treat and he couldn’t guarantee a very successful rate of success, since the floater was way in the back of the eye. He told me the success rate in my particular case would be 0 to 80% and there was a risk of pushing the floater further back, thus making it even more noticeable. Well, it would be the risk or living with the current floater, so I decided to give it a try. I’m VERY happy with the results. I consider my improvement to be 90%. I usually don’t see any floaters when using the computer anymore and when I’m reading I never see them either. The only time I see floaters now are when I look at a very bright background or on a very bright sunny day, but they’re still less noticeable than the big floater I had before. I would do it again, if I ever have another floater. It’s been truly a blessing to be able to see things again without a floater being there all the time! I hope other people will not listen to their ophthalmologists’ suggestion that there’s no treatment for eye floaters and will benefit from this procedure. Only those who have eye floaters truly know how annoying and distractive they can be!

Editor’s Response: Thank you for commenting, Mark. I’d would like to state right now, however, that using a laser on floaters is NOT a good thing, and should not be considered a valid option for dealing with them. It sounds as if YOUR laser went well, but you are lucky that the laser shockwave did not cause a retinal detachment.

There are many things that CAN be done in medicine, the question becomes SHOULD they be done. Vitreous laser for visual floaters falls WAY WAY WAY outside of the accepted standard of care in ophthalmology. It is not a procedure I (nor any other ophthalmologist that I know) would perform on any patient. The risk of creating a retinal detachment in an otherwise healthy eye is unacceptable. Thank goodness yours ended up ok.

Reply/question to Editor: it appears a double standard that the opthalmological profession, when applying its skills and technologies to “healthy” eyes, strongly promotes Lasik but frowns upon laser treatment of troubling, persistent vitreal opacities. Understood that in the latter case the laser is focused on a point closer to the retina, but Lasik is presented as benign and cosmetic when it is not uniformly so and subjects a “healthy” eye to actual instrumentation and cutting/lasering beyond what occurs in a floater procedure.

Do you dispute the claims of the laser floaterectomy practitioners that the available, albeit limited, world literature and experience in this procedure has resulted in nil retinal detachments?

A good point Bruce, and perhaps one of the reasons I’m not particularly interested in performing LASIK at this time. Messing up potentially normal eyes is not the reason I went into medicine. I’ve had LASIK however, and am glad that there are doctors performing this surgery as it has improved my quality of life. The public perspective of Lasik surgery is generated by a few aggressive surgeons, and does not necessarily reflect the opinion of the profession. Despite some misgivings, I still feel that LASIK is still a valuable surgery for many people, but the risks need to be emphasized.

Now … to your comparison of LASIK with intra-ocular laser:

The major complication risk from lasik I’ve seen quoted as 1 in 8000 (0.012 %).

The risk of complications with INTRA-ocular YAG laser (for floaters) may be much higher. Some report the rate of retinal detachment after a Yag capsulotomy (a similar type of laser used for blasting floaters) at almost 1%. This is orders of magnitude more risky than lasik. This risk may be even higher with floater-laser … or it may be less as the shockwave occurs further from the vitreous base.

Like any other surgery, it is the person suffering from floaters who must decide if their symptoms warrant this kind of risk. If the floaters are so bad that they can’t function, and they understand they may lose vision, than so be it. People should have control over their own health and destiny.

The difficulty will then be to find an eye doctor willing to take on the legal/professional liability of performing this procedure. Despite a few bad apples, the vast majority of doctors are good people who want to do the best for their patients - and I would venture that the vast majority of them would NOT do this procedure.

Medicine moves quickly, so perhaps this procedure will be perfected and proven to be a reasonable low-risk treatment in the future.

Many thanks for your measured and quick reply. Mark’s original comment represents a fortunately successful case (hoping this remains so without the later development of complications - would be happy to see a follow-up comment from him), but less positive outcomes have been anectodally reported in similar forums (mostly lack of efficacy, increase or return of floaters).

In any case, it certainly strikes as prudent to wait at least 9-12 months before even considering laser treatment of floaters (for hopeful spontaneous improvement/resolution), and even then to obtain a 2nd or 3rd opinion before deciding upon such an undertaking.

Thanks again.

Well said, Bruce. Thanks for posting!
