Flying mosquitoes is a common eye disease, mostly seen in the elderly and highly myopic patients, mainly manifested as floating black objects in front of the eyes, these objects can be dotted, stripes, mesh, one or several together, with the rotation of the eye and move, especially when looking at the white bright background symptoms are more obvious, because as mosquitoes in front of the eyes, so called “flying mosquitoes “. The vast majority of mosquito flying is benign, and does not affect the normal visual function, but if there are a large number of or multiple black shadows, or complications such as photophobia, pain, excessive tear production, visual field defects, or their own high myopia, diabetes, hypertension and other diseases, it may be a sign of serious eye disease (such as retinal detachment, vitreous hemorrhage).
Etiology
Vitreous liquefaction and posterior dislocation are the main causes of mydriasis, causing it in 70% of patients, but 25% of patients may have other vision-threatening pathologies in combination, such as retinal fissure formation, intraocular inflammation, intraocular hemorrhage, etc. Therefore, when miosis occurs, the fundus should be examined carefully, including slit lamp triangulation, ocular ultrasound, etc. If there is only posterior vitreous detachment, no special treatment is needed, and the lesions that endanger vision should be treated according to the relevant principles.
Retinal fissure: In the process of posterior vitreous detachment, a few patients can tear off the retina due to traction causing fissure. If the fissure is not treated in time, the liquefied vitreous body will enter the retina through the fissure and cause retinal detachment, resulting in visual impairment, visual field loss or even blindness.
Intraocular inflammation: When intraocular inflammation occurs, the black shadows in front of the eyes are mostly dusty or flocculent, and vision can be affected to varying degrees, with dusty and flocculent floaters in the vitreous body under the examiner’s eye.
Intraocular hemorrhage: manifested as black shadows in front of the eyes like moving clouds of smoke or ink-like downflow, with individual red or orange floaters, and intravitreal flakes, flocculent and mass hemorrhages of varying thicknesses seen under the examiner’s eye or slit lamp. Hemorrhages caused by posterior vitreous detachment traction vessels are often accompanied by retinal fissures and should be noted.
Classification
Physiological causes Physiological causes account for 20% of the cases, which means that there are impurities in the eyes, a little bit or two of black shadow, flying around in front of the eyes, sometimes visible, sometimes not. When people are very tired and tired, they will feel the mosquitoes move especially obvious, and when older people have flying mosquito phenomenon, they will feel more intense and obvious than middle-aged people’s flying mosquito phenomenon. Most of these patients are under 40 years old, and see only a few dots in front of the eyes.
Degenerative causes: degenerative causes account for 75%, it represents the eye vitreous degeneration, causing the vitreous and retinal separation, these patients are mostly in the 40 years of age or older, and see only a little bit of mosquitoes in front of the eyes.
Pathological causes: pathological flying mosquitoes generally caused by serious diseases, is due to the vitreous near the retina, optic nerve, ciliary body and other tissue lesions and vitreous changes, it only accounts for 5%, but it will affect vision, and sometimes even cause blindness.
Pathological mosquito flying disorder has 3 characteristics.
1, there is an abnormal flash.
2, increasing number of flying mosquitoes in a short period of time.
3, vision has been blocked feeling. This kind of pathological flying mosquitoes also has many reasons, such as: vitreous hemorrhage (such as: diabetes, hypertension, eye wind); retinal fissure, retinal detachment; vitreous inflammation, retinitis.
Treatment
Most of the physiological and degenerative causes of mosquito flying do not need to be treated, just need to pay more attention to eye health, do more outdoor sports, practice gymnastics, eat more vegetables, fruits and so on. The use of drugs to improve circulation or iodine can help, while pathological mosquitoes need to be treated symptomatically.

Vitamin A is an essential nutrient for the eye; vitamin C, vitamin E can destroy free radicals, improve eye immune function, to prevent vision loss; B vitamins can promote the metabolism of cells in the eye, very helpful to patients with eye disease.
