Shroud in the eyes: causes and treatment. Causes of blurred vision
It happens that the picture suddenly diffuses in front of the eyes. The colors become less bright, the objects lose their clarity, the surrounding world plunges into a "fog".Shroud in the eyes - a fairly common phenomenon, but, alas, not harmless. Thus, the body signals serious illnesses that can lead to loss of vision. Especially dangerous are the conditions when the shroud is not like a thin film, but a cloudy, dark or red glass. Such a symptom warns of a violation of the transparency of the ocular media or problems of recognition of the resulting image of the occipital cortex of the brain.
Where to go
If you have a veil in your eyes, blurry vision, then first of all you need to contact an ophthalmologist. It is this specialist who must conduct the initial diagnosis and determine the cause of the ailment. If the ophthalmologist does not find any violations, then a consultation of the neurologist is needed. The main thing is not to delay the treatment, because you can miss the time.
White Shroud. Cataract
The white veil in the eyes is most often a symptom of eye diseases. In many cases, this can be a one-way process involving only one eye. Often patients with such complaints are diagnosed with cataracts, that is, a violation of the transparency of the lens.
Lens is a "biological lens" created by nature to refract light. It is located on the ligaments inside the eye and does not have its own blood supply. Lens nutrition is provided by intraocular fluid. At a certain point, as a result of natural aging or metabolic disorders, the transparency of the lens deteriorates. At this moment, a veil appears in the eyes, a vague vision, objects begin to double, eyes catch obsessive flies, the picture turns yellow, it becomes harder to read, write and work with small objects.
A person does not feel any pain in cataracts, this creates a deceptive feeling that nothing supernatural happens. However, the quality of life gradually worsens, twilight vision weakens, tearing begins in bright light, it is more difficult to read, more powerful lamps are needed, halos around the light sources, and patients with farsightedness gradually stop using glasses.
Constant shroud in the eyes may be a symptom of glaucoma. This disease is associated with a steady increase in intraocular pressure, as a result of which intraocular hypertension begins, as unhindered drainage of the intraocular fluid is disturbed. The process is very dangerous, it can lead not only to impaired vision, but also to a complete irreversible loss. Suffice it to say that out of the total number of blind people, 15% lost sight as a result of glaucoma.
Glaucoma is divided into two forms:
- Open-angle. This means that the outflow of fluid in the anterior eye chamber, which is in front of the lens, was disturbed. This pathology is considered less dangerous, as it develops gradually, leaving time for action. With the open form of glaucoma, the angle of vision gradually decreases( with a separate speed for each eye), a veil appears in the eyes and iridescent circles in front of them. Headache worsens, twilight vision worsens.
- Closed-angle. This means that the blockage of the outflow occurred in the area of the connection between the iris and the cornea. This place is the main exchange of fluids in the anterior and posterior eye chambers. At the first stage, the disease does not cause discomfort. The reasons for the deterioration of vision to the patient are unclear. Then there is an acute attack, during which the outflow of fluid is completely blocked. There is a sharp pain in the head and eye, which is often confused with migraine. The vision falls rapidly, a shroud appears, dizziness and vomiting begin. The eye, in which an attack of angle-closure glaucoma occurred, turns red and becomes dense. Nature has given very little time to remove the outflow blockage. Sometimes it's only 3-4 hours. Then vision is lost irrevocably.
As already mentioned, if there was a veil in the eyes, the reasons do not always lie in the field of ophthalmology. If, as a result of the inflammatory process, the optic nerve reduces sensitivity, then the image from the retina does not reach the brain. This problem is called "optic neuritis", and it is treated by a neurologist. In addition to inflammation, the cause of neuritis may be a demyelinating disease( destruction of the immune system by the myelin sheath of neurons).
A veil in the eyes, the causes of which are optic nerve neuritis, may be accompanied by partial or complete blindness. The severity of the disease depends on the degree of damage to the diameter of the nerve.
A few more reasons for the white shroud
In addition to the above diseases, the appearance before the eyes of a white shroud may be caused by:
- occlusion of the central artery in the retina;
- corneal disease;
- senile farsightedness;
- brain tumor;
- uncontrolled reception of glucocorticoid agents, antidepressants, contraceptives;
- with dry eye syndrome.
Dark Shroud. Migraine
Shroud before the eyes can be not whitish, but dark. This symptom is characteristic for several diseases, one of which is a migraine. In this case, the causes of visual impairment are neurological and are accompanied by a painful unilateral headache. Most often, patients have a genetic predisposition to migraine. Attacks of pain cause not only blurred vision, but also dizziness, nausea, speech disorders, sometimes even hallucinations.
This is a problem associated with the detachment of the inner shell of the eye containing photoreceptor cells. The retina in the place of detachment does not receive nutrition from the choroid, and it dries. The process is gradual, it starts with light flashes, zigzag lightning and black "flies".Then there is a partial or complete dark veil in the eyes. What to do in this case? Urgently run to the doctor! Minor detachments can be "soldered" without serious consequences. But if the process is started, then the shrunken retina will not be fixed. Vision will be lost.
The red veil in the eyes of
And one more dangerous symptom is a red shroud. This means that blood has poured out into the vitreous or surrounding space, that is, a hemophthalmia occurred. Shroud in the eyes in this case can talk about the complication of diabetes, the development of atherosclerosis, hypertensive disease or retinal dystrophy. Hemophthalmus can also occur due to retinal detachment and eye injuries of varying degrees of complexity.
A red shroud is accompanied by blurred vision, the appearance of shadows, flies or stripes. If the hemorrhage happens as a result of glaucoma or trauma, then an additional symptom will be pain.
Why it is important to describe the accompanying symptoms correctly
To make the correct diagnosis, it is not enough for the doctor to hear from the patient: "I have a veil in my eyes in the morning."To understand in what direction to move, the description of the accompanying symptoms will help. So, for example, if the appearance of a shroud is accompanied by weakness, then it can be low pressure, anemia, VSD, hypertensive crisis. If chaotically moving flies appear along with the shroud, then cataracts, hemophthalmia, retinal detachment, brain tumor( in the occipital part), migraines and others are added to the list of possible diseases. If dizziness is added to the listed symptoms, it can be a stroke, internal bleeding, cerebral atherosclerosis, poisoning and so on.
Because there are many variants of the diseases, it is necessary to describe the condition to the doctor as accurately as possible.
Diagnostic examination of
Since first of all patients turn to the ophthalmologist, examination with a slit lamp, eye tonometry( measurement of intraocular pressure), hardware examination of the fundus, ultrasound will be performed. If the ophthalmologist does not reveal pathology, then the patient is redirected to the neurologist.
The neurologist determines reflexes and sensitivity, prescribes dopplerography of the vessels( head, neck), MRI( head, neck).
Shroud in the eyes: treatment of
There are many factors that lead to problems with eyesight. And every disease, the symptom of which could become a veil in the eyes, requires appropriate treatment. So, for example, with retinal detachment, medication is prescribed, which improves vascular patency and metabolism. In addition, laser coagulation( soldering) of the retina is performed.
With cataracts, in its initial stage, vitamins and nutrients are prescribed for instillation into the eyes. At later stages, an operation is performed to replace the lens.
When glaucoma is prescribed drugs that reduce pressure inside the eye. If necessary, the outflow is restored by surgical intervention.
The main thing that a patient should understand: a doctor needs time to take measures to preserve his vision. Do not ignore the shroud in the eyes, especially if it often repeats or keeps steadily.
