Eye floaters are protein and debris floating around in the gel-like fluid inside the eye, known as the vitreous humor. Often, what is seen by the person are not the floaters themselves, but rather their shadow. Persons with this condition describe seeing specks of dust, squiggly lines, or cobwebs in their field of vision. Often, these shapes are seen to dart around, and they are more visible in brightly-lit conditions. They are annoying but generally harmless; however, you should always seek medical advice to make sure that they are not a symptom of a more serious underlying condition. You should also see your doctor again if your eye floaters suddenly change in number or density.
Anyone can get floaters, but they are more common in older adults. Eye floaters are usually caused by age-related changes and damage that occurs to the vitreous humor, or because the vitreous humor detaches itself from the posterior part of the eye. They may also be triggered as a side effect of some medications, as a complication of diabetic retinopathy, and by an inflammation or infection of the eye.
Medical eye floaters removal involves either surgery using a YAG (Yttrium Aluminum Garnet) laser or a procedure called vitrectomy. YAG laser eye floaters removal utilizes a special, precise laser to break up individual eye floater particles. This is a very specialized procedure and carried out by only a few specialists in the whole of the USA. In addition, there are a number of risks associated with it, and not everyone with eye floaters is eligible for this procedure.
Vitrectomy is a different type of surgical eye floaters removal and involves removing part or all of the vitreous humor (together with any floaters in it) and substituting it with a saline solution. This procedure too is associated with a number of complications, the most common of which being bleeding in the eye, development of cataracts, and high pressure in the eye. It can also cause retinal detachment and infections.
