When looking at the bright background, there are small black shadows flying in front of the eyes, like mosquitoes floating through, so the name flying mosquitoes. Many patients worryingly ask: “suffer from mosquito flying disease eyes will not be blind?” Ophthalmology experts: most of the flying mosquitoes no obvious harm, will not affect the visual function, no special drug treatment. But a few of them are serious eye disease, here to remind you should not take it lightly. What is mosquito flying syndrome? Under normal circumstances, light passes through the cornea and lens, and then through the transparent vitreous to reach the retina. Vitreous humor is a gel-like transparent material, once it for some reason and produce “cloudy”, look at the bright background, this “cloudy” shadow will be reflected in the retina, and with the movement of the eye and move, this is the flying mosquitoes. The types of mosquito flying disorder is medically divided into physiological mosquito flying disorder and pathological mosquito flying disorder. In most cases, mosquitoes is benign, or physiological mosquitoes, very few belong to the pathological mosquitoes. Physiological mosquitoes physiological mosquitoes can generally be divided into three kinds: congenital physiological mosquitoes, senile physiological mosquitoes and myopic physiological mosquitoes. On the basis of eye examination, these three types of physiological mosquito flying disorder once diagnosed, not must be treated, but also can not be careless, should be checked once every six months to a year. If the black shadow area suddenly increased may be a sudden change in the condition, must be examined and treated as soon as possible. The cause of physiological mosquito flying disorder may be excessive eye use, excessive stress or long-term psychological depression. The specific cause is difficult to find, but it does not require any medication to treat. Pathological mosquito flying disorder and physiological mosquito flying disorder is different, pathological mosquito flying disorder must be treated promptly. The causes of pathological mosquito flying disorder are complex, mostly caused by medium to high myopia, physical trauma caused by internal bleeding or inflammation of the eye. If the diagnosis of pathological mosquitoes, to be alert to the following diseases: retinal fissure, retinal detachment, vitreous hemorrhage and uveitis. At this time, patients had better go to the hospital for detailed examination as soon as possible, in case unfortunately suffered from serious fundus diseases, but also in time to get the most targeted treatment. How to prevent flying mosquitoes pay attention to eye health, avoid excessive use of the eyes, regular eye examinations; reasonable dietary arrangements, eat more eye-friendly food, improve eye immune function; more outdoor sports, increase immunity, high myopia to avoid strenuous exercise and external impact; regulate the work and rest time, maintain good habits, pay attention to rest, relaxation. How to treat mosquitoes once diagnosed with pathological mosquitoes, need to be treated according to the different causes of clouding. Treatment of retinal fissure can be used to laser coagulation around the fissure to prevent retinal detachment; if retinal detachment has occurred, it must be hospitalized for surgery. Vitreous hemorrhage: Diabetes, hypertension and trauma may cause bleeding in the fundus, and once the blood enters the vitreous it will suddenly show symptoms of flying mosquitoes. Due to the amount and location of bleeding, can cause different degrees of vision loss, if the bleeding is small can be self-healing, generally use hemostatic drugs and drugs to promote blood absorption to treat, can also use laser and surgical treatment. Uveitis: can be treated with systemic or local anti-inflammatory and anti-infective drugs or eye drops.
