There are always people in front of the eye like mosquitoes or flies, black dots or black lines, or even cobweb-like black shadow floating, and, often in the blue sky, white walls, reading and writing, or the body is more tired, eye fatigue is easy to appear, this is the so-called “flying mosquitoes” that plague many people. In fact, “flying mosquitoes” is only a patient’s conscious symptoms, mainly because of the eye vitreous clouding and caused. So, flying mosquitoes and how the formation of it? The normal vitreous body of the human eye, such as the egg white, is a transparent gel, but in the case of high myopia, or with age, the vitreous gel will gradually degenerate, and in the intersection of gel and liquid, concentrated aggregation of gel will produce shadows projected on the retina, so the formation of flying mosquito symptoms. Causes of “mosquito flying” and also due to retinal detachment, rupture produced a small amount of intraocular hemorrhage. In addition, people suffering from diabetes, hypertension and other diseases or too much socializing, frequent late nights are also prone to “flying mosquitoes”. Found the “flying mosquitoes”, how should we deal with it? The correct approach is to find an ophthalmologist as soon as possible to determine the nature of “flying mosquitoes”. There are many patients will be worried to ask: “suffer from mosquito flying eyes will not be blind?” Generally speaking, due to age-related vitreous degeneration, coupled with eye overuse, fatigue, etc. caused by flying mosquitoes is a harmless vitreous turbidity, most of the flying mosquitoes do not affect the visual function, no special drug treatment. As long as appropriate rest, avoid strain, to do a reasonable diet and living, to develop good eye hygiene habits, such as prolonged eye rest every hour for 5 to 10 minutes, the use of computer time is not too long, self-conscious discomfort to pause the use will improve, eat more vitamin C and lutein-rich food, such as vegetables and fruits will also help. Although the vast majority of mosquito fly without obvious harm, but a few of them are serious eye diseases, such as retinal detachment or vitreous hemorrhage and other precursor symptoms, so we must not take it lightly. The following phenomena need to be particularly vigilant, promptly find a qualified ophthalmologist detailed examination: for example, severe vision loss, visual distortion or distortion; eye redness, pain, photophobia and excessive tearing; with a fixed black shadow; flashing lights; sudden appearance of a large number of black spots, etc.. If it is due to more intraocular hemorrhage, retinal detachment and other causes of flying mosquitoes, surgery is required. In addition, it is worth noting that: if mosquito flying disease persists, suffering from high myopia, or the presence of risk factors for retinal detachment, you should ask the ophthalmologist to do a fundus examination every three months to six months, in order to timely detection, timely diagnosis and timely treatment.
