Can Lasers Blast Away Those Weird Squiggles at the Corners of Your Vision Youre staring at the sky on a sunny day when you notice, in the corner of your eye, a transparent squiggle floating slowly across the blue.

What youve got is a floater, a tiny piece of protein floating around the vitreous humor, the gel in the back of your eye. But for some people these floaters get worse with age and can become quite large. So a team of scientists want to know if they could safely treat these distracting dots with lasers. Laser treatments have existed for at least 1. Porter Value Chain Template Powerpoint on this page. Ophthalmic Consultants of Boston write in the paper published today in JAMA Ophthalmology. This is particularly important because of the strong possibility for a placebo effect. The authors recruited 5. They treated 3. 6 patients with YAG laser vitreolysis, which pulses a special kind of laser into the eye. Sixteen control patients instead received a sham treatment with a special filter and the laser on the lowest setting, preventing the lasers energy from entering their eye. Of the 3. 6 patients, 1. None of the sham group said thatall of them said their negative symptoms were worse, the same or somewhat better. Batman Arkham Asylum Save Game Crack here. More importantly, 3. YAG laser group lost most or all of their floaters, something that no members of the sham group reported. Procomm Plus 2.1 Patch. The authors reported several limitations to their studyit was small, it compared YAG lasers to a sham instead of other treatment options, and the follow up period after which the researchers checked on the patients to see how they were doing was relatively short, only six months. It also might not reflect what the treatment would really look like in a clinical setting, and probably cant be generalized to all floaters, but just to the specific cases they treated. Those include much larger floaters more common in old people that come with flashes in vision and other symptoms. But one expert, Jennifer Lim from the Illinois Eye and Ear Infirmary at the University of Illinois at Chicago, wrote in a comment that a lot more research is necessary before declaring the treatment safe. The authors of the new study selected their patients carefully, which could have aided to their studys success. She also noted the short follow up period meant some long term adverse effects could be missed. Despite a reported low rate of complications, it was not proven that YAG vitreolysis is a safe procedure, she wrote. So maybe were not ready to start busting floaters with lasers just yet.
