Reasons for the appearance of flies before the eyes

Indeed, many people face flies before their eyes.Most of them do not pay special attention to this phenomenon.But there are people who are hypochondriac, who have noticed flies before their eyes, begin to panic and seek out the causes of pathology.

Mushki-v-glazah Flies in front of the eyes will be especially noticeable if you look at any light surface.Melting points and strips in the eyes can be seen by any person, if he looks, for example, on a clear blue sky or white snow.Also, flies begin to flash before your eyes, if you look closely at the sun, a bright light bulb.This is absolutely normal phenomenon and soon the flies disappear.

There are situations when such a visual effect is observed by a person for a long time and this brings him discomfort.In this case, you need to seek advice from an ophthalmologist or a therapist. Melting of dots before the eyes can be a sign of both ophthalmic and somatic diseases.

Diseases of the eye

Than-dangerous-destruction-vitreous-body Very often the reason for the appearance of flies lies directly in the eye itself, namely in the vitreous body. It is a gel-like substance that fills the cavity of the eye.The vitreous humor consists mainly of water, collagen fibers and hyaluronic acid.In the natural state, the vitreous body is transparent.However, sometimes the decomposition( destruction) of structural proteins occurs, because of which opaque particles are formed.When the light beam passes through the vitreous body, it encounters these particles, which are projected onto the retina in the form of shadows.Therefore, the effect of flies before the eyes occurs.

Similar transformations are called destruction of the vitreous body.This process inevitably overtakes a person in old age, but it can also occur in young years. People with myopia are especially susceptible to destruction of the vitreous humor.

The causes of the flickering flies before their eyes can also be caused by such diseases:

  1. The detachment of the posterior part of the vitreous;
  2. Hemorrhage in the eye;
  3. Injury of the eye;
  4. Peripheral dystrophy of the retina;
  5. Retinal detachment;
  6. Uveit.

The most dangerous condition of the list listed above is retinal detachment, since this ailment can lead to blindness. The detachment of the retina is evidenced by the sudden influx of many flies in front of the eyes, as well as the appearance of light flashes - lightning.If such symptoms occur, you should urgently consult an ophthalmologist.

Vessel Diseases

The cause of the appearance of flies is not always concealed in ophthalmic diseases.Often this phenomenon accompanies fluctuations in blood pressure .At high and low blood pressure, blood supply to organs, including the eye, is impaired.Due to poor blood supply to the retina, sight is visible in the field of vision.Sharp spasm of blood vessels at high pressure and can at all lead to a rupture of the capillary in the eye, this can also become a direct cause of the appearance of flies.If the capillary ruptured in one eye, then the flies would be observed in the field of view of one eye.

People with diabetes face flies before their eyes.With this disease, the retina vessels are affected with the development of diabetic retinopathy.Vessels become brittle and may break.The accumulation of blood leads to the appearance of flies in the field of vision, swaddling before the eyes, reducing visual acuity.

Vascular disease

Brain diseases

Flashing before the eyes, flies can be a sign of a neurological disease. Such a disease as migraine is characterized by a prolonged and painful headache in one half of the head.The appearance of harbingers indicates the beginning of the attack.This period is called a migraine aura, which can be accompanied by the appearance of flies, light flashes, blurred vision, the emergence of simple hallucinations, speech disturbance.

Craniocerebral injury leads to a number of neurological disorders.So, the victims themselves at the time of injury can see the flashing of flies in sight and even "sparks" from the eyes. In favor of CCT, the following symptoms also indicate:

  • Loss of consciousness;
  • Severe headache;
  • Dizziness;
  • Nausea and vomiting;
  • Memory loss;
  • Convulsions;
  • Violation of speech, etc.

The reason for the appearance of flies in the eyes may be a tumor of the occipital lobe of the brain .This is not surprising, because the occipital lobe of the cerebral cortex is responsible for the processing of visual information and visual perception.Therefore, tumors in this area are accompanied by flies, light flashes in the field of vision, photopsy( the appearance of circles, asterisks, simple geometric figures).As the tumor process progresses, visual disturbances become more pronounced: the visual fields fall out, the color perception is disturbed. Nevertheless, when flies appear, one should not immediately think about the tumor of the occipital lobe of the brain, because this ailment is rare.

Other reasons for the appearance of flies

The culprit of the spine may also be responsible for the appearance of flies. When osteochondrosis, the deformed cervical vertebrae squeeze the vertebral artery, which supplies blood to the brain and eyes.In favor of this ailment is the appearance of flies before the eyes, headaches, dizziness, noise in the ears, a crunch in the neck.

Flies in front of the eyes - a true companion of anemia .Reduction of hemoglobin level develops with bleeding, including hidden ones.Therefore, the appearance of flies before the eyes, weakness and fainting should be an occasion for examination for internal bleeding.


Vitrectomy surgery Before starting the fight with flies before your eyes, you need to identify the cause of this phenomenon. In those cases when during the examination the ophthalmologist determines that everything is in order with the vision organ, no treatment is prescribed.If the underlying cause is hidden, for example, in hypertension or diabetes, it is necessary to tackle the underlying disease.In general, there is no universal medicine for flies before the eyes of .If necessary, the doctor can appoint the patient drops "Emoksipin 1%" and tablets "Wobenzym" for oral administration, which improve the metabolic processes.

In cases where flies are caused by the destruction of the vitreous, the ophthalmologist can offer a surgical solution to this problem.The procedure called vitreolysis consists in splitting the opaque particles in the vitreous body with a laser.Formed small particles will not interfere with normal vision.

In special cases resort to vitrectomy.This is an operation to remove the vitreous. In the empty cavity of the eye, a synthetic transparent gel is injected, after which the optical patency is restored and the flies disappear from the field of vision.

Remember that the state of the organ of vision is interrelated with the general state of the body.To prevent the appearance of flies in front of the eyes, it is necessary to eat fully, play sports, sleep, get rid of bad habits, and also promptly treat existing diseases.
