Physiological mosquitoes Most mosquitoes are age-related, like cataracts and presbyopia are caused by aging of the lens and ciliary body, mosquitoes are also caused by aging of the vitreous body. The vitreous body is clear in children, as age increases, the vitreous degeneration, clouding, liquefaction, concentration, and in severe cases, posterior vitreous detachment, the vitreous body in the appearance of lines or lumps. As the human body aging inevitable, caused by the aging of mosquito flying disorder is also inevitable. Flying mosquitoes also often occur in young people, in fact, vitreous transparency is relative, embryonic vitreous vascular presence, after birth, the blood vessels disappear, but some people still have residual vitreous vessels; In addition, the vitreous residual small number of cells, they are mostly scattered presence, if aggregated, will also appear cloudy objects. Nearsightedness (especially high myopia) is also the cause of mosquitoes, the anterior and posterior diameter of the eye elongated deformation, squeezing the vitreous fiber stent, resulting in the collapse of the fiber stent vitreous degeneration. High myopia patients than orthokeratology patients to occur 10 years earlier than posterior vitreous detachment. The above is physiological mosquitoes, can not be prevented and treated, therefore, we should gradually adapt to it, do not see. Some people have a heavy psychological burden, worried about the possibility of blindness, in fact, as long as you know that most people have mosquito flying disorder, you will not have these thoughts. We can find no mosquito flying friends to do a small experiment, let him look at the white wall for a few seconds and then turn the eyeballs, suddenly stop turning the point of gaze to the eye to move, see what his reaction. The symptoms of physiological mosquito flying disorder will change, such as dot to line, or location change, or stripes increase, the net density gradually increased, if not suddenly a large increase, or normal. Pathological mosquito flying syndrome and physiological mosquito flying syndrome is the counterpart of pathological mosquito flying syndrome. What is pathological mosquitoes? It is the vitreous clouding caused by the vitreous peripheral tissue lesion. Diabetes, hypertension and trauma can cause bleeding in the fundus of the eye, and blood entering the vitreous body can produce the symptoms of miosis, and severe bleeding can cause severe vision loss. Uveitis is also the cause of pathological mosquitoes, inflammation, white blood cells and exudate will be from the blood vessels into the vitreous body, thus producing symptoms of mosquitoes. For the treatment of pathological mosquitoes, the first is symptomatic treatment, for serious vitreous turbidity, can use iodine-containing drugs, it can improve the blood – eye barrier permeability, promote blood circulation. Flying mosquitoes can also be caused by debris in the tear film, often due to cosmetics or other substances in the tear collection caused. Patients with blepharitis and abnormal function of the lid gland have aggregates of debris in the tear film layer, which can cause the symptoms of mosquito flying. Eye allergic reaction, due to the secretion of excessive mucus, also have the symptoms of mosquito flying. The difference between lacrimal mosquitoes and vitreous mosquitoes is that vitreous mosquitoes can float with eye movement, lacrimal mosquitoes and eye movement, and when the transient eye, the symptoms quickly disappear. Some patients with mosquito flying disease with a flash in front of the eyes, is due to the vitreous clouding of the retinal nerve cells to produce stimulation, the signal to the nerve center caused. If the flash is frequent, it may be a retinal fissure or retinal detachment. Some of the flash in front of the eyes and mosquitoes unrelated, head blows will also cause the flash in front of the eyes, which is due to retinal shock, stimulation of the optic nerve cells results. Migraine headache can also cause the flash in front of the eyes, which is cerebral vascular spasm, affecting the optic nerve center caused by.
