A condition as in a fog: what to do, when there is a fog in eyes and a head

Reasons for fog in the head can not always be determined. In a number of cases, this functional condition is caused by overwork or chronic stress. However, there are causes of fog before the eyes, related diseases, both the organ of vision and other body systems. Due to the prevalence of this symptom, each person is advised to know about the factors and diseases that cause blurred vision, as well as the principles of treating pathology.

Causes of

The causes of fog in the eyes are divided into two large groups: leading to unilateral visual impairment, and to two-sided. The first group of causes is the most dangerous and is associated with:

• increased intraocular pressure on the one hand as a result of severe vascular lesions;
• focal hemorrhage in the organ of vision or related structures;
• by acute inflammatory processes in the eyeball.

A similar condition occurs in the defeat of the optic nerve, which is involved in the transfer of information from the receptor retina to the visual cortex of the brain. In addition, visual impairment leads to swelling of the corneal cells or the growth of tumor formations in the eyeball that cause trauma and cause hemorrhage in the vitreous. The most serious situation requiring urgent surgical intervention is detachment of the retina.

The fog in the head appears in brain diseases such as venous dyskirculation, hypoxic encephalopathies, microinsult, etc. In all cases, a decrease in blood supply to brain tissues leads to a change in the state of the cells and a violation of their functions. If this happens in the occipital part of the cerebral cortex, where the visual centers are located, then a person has "flies" or fog before his eyes.

As a rule, such a situation is temporary and after a few seconds or minutes the symptoms completely pass. Similar manifestations may accompany vascular diseases in the brain: atherosclerosis and narrowing of the lumens of the cerebral arteries, providing blood supply to the brain tissue;Vasculitis( inflammation of the vessel wall) with edema and constriction.

The frequent cause of the transient decline in vision is poisoning. Ethanol and methanol occupy the first place in the structure of toxic substances. Excessive consumption of alcoholic beverages, can lead to severe intoxication and toxic effects of ethanol on the brain. Visual disturbances are a specific symptom for methanol poisoning and, in some cases, progress to complete blindness of the patient.

The appearance of the condition as in a fog arises in any form of glaucoma - a disease associated with increased intraocular pressure. In this case, in addition to visual impairment, there is severe pain in the eye, headache and nausea. Perceiving visual impairments indicate angiospasm - temporary spasm of the eye vessels leading to hypoxia of its individual parts and disruption of work. A similar situation is associated with hypertension, smoking and other causes.

Two-sided fog in the eyes is associated with systemic diseases of the body and results from:

• diabetes mellitus and development of small vascular lesions;
• diseases of the cardiovascular system associated with hypoxia;
• chronic and acute renal insufficiency;
• with preeclampsia and eclampsia in pregnancy;
• intoxication.

Manifestations and complaints

The appearance of fog in the eyes is described by the patients in different ways. A number of patients complain of a veil before the eye, which prevents the world from clearly seeing. Someone sees constantly flashing dots or "flies" that disrupt normal vision.

With a severe underlying disease involving eye damage, the patient looks as if through a misted glass. In most cases, the appearance of fog leads to a violation of vision, a drop in range and clarity of vision.

The fog in the eyes appears for a different period of time - from a few seconds, to several hours or even days. Patients complain that in the fog in the head there are inhibitions and indifference.

Diagnosis of the disease

When fog in the eyes or sense of "head in the fog" is necessary to consult a therapist or ophthalmologist. Collection of complaints, data on risk factors and concomitant diseases, can lead the doctor to the correct diagnosis. For its confirmation, both general clinical studies and special ophthalmic studies are carried out.

The first include a general and biochemical blood test, a general urine test. These methods allow to detect the presence of an inflammatory process in the body, to assess the level of glucose in the blood to exclude diabetes and to assess the overall condition of the patient.

One of the key methods in establishing the correct diagnosis is a biomicroscopy with a special ophthalmic microscope or slit lamp. If there is inflammation in the surface of the eye, then hyperemia and edema of these layers will be clearly visible. With uveitis( inflammation of the choroid), leukocytes and lymphocytes, inflammatory cells, appear in the middle shells of the eye. In addition to them, there are cellular aggregates, inflammatory fluid, and in the long course - adhesions.

Evaluation of the vitreous transparency allows detection of pathological changes. In addition, all patients with this symptom should undergo a measurement of intraocular pressure, since it is glaucoma that is very often manifested by the appearance of transient visual impairment. When suspicion of pathological processes in the brain, patients are referred to an MRI or CT scan.

When blurred vision should always seek medical attention, especially if the symptom persists for several days or unilateral manifestation. Only the doctor knows the right answer to the question of how to get rid of fog in the head.

The main approach in treatment is the effect on the cause of the disease. If the patient is diagnosed with diabetes, then appropriate therapy with insulin and other drugs should be prescribed, as well as recommendations for changing lifestyle and nutrition. In the case of the presence of glaucoma, prescribe medications that promote the outflow of intraocular fluid and reduce the pressure inside the organ of vision.

If the causes of fog in the eyes are associated with pathological processes in the brain, a violation of blood flow, further treatment is prescribed by a neurologist. When a brain tumor is detected, patients are referred for advice to an oncologist.

To correct vision and remove "fog" apply corrective lenses or glasses, restoring clarity and range of vision.

The appearance of fog or "flies" before the eyes may indicate the development of a serious disease. Therefore, you should not postpone your visit to a doctor. Timely diagnosis and proper selection of treatment methods and glasses, in most cases, allows you to quickly cope with the disease, restore your eyesight and prevent the development of complications.
