What do black flies say and the white veil before your eyes?

Black flies before the eyes - a symptom of a disease of the organs of vision, or the nervous system. Sometimes impaired perception of vision is caused by a decrease or increase in pressure inside the skull, a consequence of a traumatic brain injury. Black flies as a visual defect can also occur after operations on the eyes. If there were flies before your eyes, what to do? To diagnose the causes of this phenomenon, it is necessary to visit an oculist or ophthalmologist, as well as a neurologist.

Causes of visual defects

A white veil before the eyes can be a sign of a serious disturbance, both in the eye itself and in signal transmission through the optic nerves and pulse analysis by the centers of vision in the occipital lobes of the cerebral hemispheres. Neurotrophic disorders occur during metabolic shifts, circulatory disorders in the organ of vision, especially in the retina.

Causes of the appearance of flies before the eyes:

1. Cataract( with diabetes including).
2. Retinal detachment and hemorrhage in her.
3. Hemorrhage in the vitreous.
4. Consequences of hypertension - retinal edema.
5. Dystrophy of the vitreous body, as well as a yellow spot and lens.
6. Brain Injury.
7. Strokes.
8. Peripheral neuropathy in diabetes mellitus, vitamin B1 deficiency. This may affect the optic nerve.
9. Infections of the central nervous system.
10. Edema of the optic nerve.
11. Glaucoma.
12. Tumors of the pituitary and central nervous system.
13. Disturbance of cerebral circulation in atherosclerotic processes in carotid arteries.
14. Blinding bright sun, snow.
15. Epilepsy or eclampsia in pregnancy.

The violation of perception in the form of the appearance of artificial objects( flies or veils) that do not exist in reality, is sometimes due to damage to the vitreous. It has transparency and a homogeneous structure, it is part of the light refracting apparatus of the eye.

In dystrophic processes caused by a metabolic disorder or aging, as well as free radical oxidation, the structure is stratified. Connective tissue fibers of the matrix and mucopolysaccharides of the vitreous are dehydrated, which leads to a decrease in its transparency.

This is manifested by the appearance of artifacts in the visual perception. Violation of the integrity of the vessels of the fundus in thrombosis can lead to hemorrhage in the vitreous. The same thing sometimes happens with increased intraocular pressure.

Cataract is a lens disease in which this biological lens loses its light transmitting ability. Thus the patient also can see white flies before eyes. Dystrophic processes in the lens can be caused by free radical reactions, as well as metabolic shifts in diabetes mellitus.

Damage to the retina by a hemorrhage or with trauma, moderate burns can also cause the appearance of artifacts in the field of view. Flies can be a sign of glaucoma, in which the outflow of fluid through fountain spaces is disturbed.

Important! Diseases of the brain can also lead to impaired visual perception. For example, tumors of the pituitary gland and other formations of the central nervous system can squeeze the intersection of the optic nerves.

In chronic arterial hypertension, the retina of the optic nerve papilla may appear on the retina, which gives symptoms of flies or white veils. Edema of the brain with epilepsy and eclampsia is also accompanied by visual artifacts, as well as photophobia before the attack. Edema of the optic nerve is possible with allergic reactions, which can also be accompanied by visual impairment.

Diagnostics

What do front eyes mean? For the most accurate answer to this question, a thorough examination from the oculist and ophthalmologist will be required. Studies include ophthalmoscope examination of the fundus with dilated preparations of belladonna pupils, measure intraocular pressure. An ultrasound examination of the eyes may be prescribed.

In the absence of pathologies on the part of the visual analyzer, it is recommended to visit a neurologist for diagnosis of diseases of the nervous system. A neurologist can prescribe magnetic resonance diagnosis of the brain. Echo and electroencephalogram allow to see signs of intracranial hypertension.

Treatment

How to get rid of flies before your eyes? With organic damage to the tissues of the eye, as with cataracts or vitreous dystrophy, detachment of the reticular membrane, treatment is ineffective. However, for the resolution of pathological formations drops of potassium iodide can be prescribed, which can also remove the edema. In flies caused by glaucoma, drops that reduce the pressure of the liquid are used.

When the intracranial pressure falls or rises, and flies appear before the eyes, treatment of this condition consists in normalizing the pressure by prescribing special preparations. Reduces intracranial pressure of Cinnarizine. With atherosclerotic occlusion of the carotid arteries and darkening in the eyes, funds are prescribed for lowering cholesterol and homocysteine ​​levels. Hypertension requires therapy with antihypertensive drugs.

Conclusion: regular flies - a serious symptom, requiring diagnosis from an ophthalmologist and a neurologist with the use of special equipment. Treatment is conducted after the exact establishment of the cause.
