A lot of people around the world suffer from a rather harmless eye condition called eye floaters. In such cases, people see fuzzy, web like structures floating around their eyes all the time. And the more you try to focus on them or chase them, the quicker they appear to go away. As mentioned earlier, a majority of population suffers from such condition. But the question that troubles many is that whether it is harmful or not?
So what exactly are floaters of the eye?
Those particles that appear bit like webs or dust particles are actually known as muscae volitantes in medical terms. It can be defined as particles, spiders, spots, rings, etc. that constantly float in the field of vision. Almost everybody suffers from this condition at some or the other point in their life, but it is more commonly found in people suffering from myopia or near sightedness.
Floaters are actually the remains of hyaloids artery, an artery that is responsible for the nourishment of eyes during the development of fetus. As you grow up, this artery begins to deteriorate and wither away. During this process, some of the humor inside the artery gets left behind in eyes. This debris can cause floaters in the eyes.
There are some other reasons as well which can lead to floaters. One among them is retinal tears. This can happen when red blood cells get leaked into the eyes from leaking blood vessels. Asteroid hyalosis, which is basically the anomaly of vitreous humor, can also cause calcium clumps, thereby leading to floaters.
Are they harmless? The answer is generally no, but there might be cases when you need to consult an eye specialist to get them treated, especially when they are making it difficult for you to concentrate on objects. So they may not always be benign. Sometimes floaters can be a result of external or internal injury to the head, which in turn can lead to hemorrhage of tiny vessels. Eye infections can also cause floaters. So if you are experiencing a sudden shower of floaters in the eyes after an accident or injury, then you must visit an eye specialist as soon as possible to get the condition treated or your vision might be impaired.
Eye surgeons perform a surgery called vitrectomy to treat such a condition. In this surgery, the fluid present inside your eyes is removed and then replaced with similar but inert substance. This removes floaters forever.
