Double vision (as the phenomenon is called diplopia ) - It is a symptom in which a person sees one object as two different images. This is due to the lack of binocular movement, which defines the mapping of visual images.
How does double vision?
When double vision when looking at the man the world sees one thing as two images. Ghosting is often accompanied by the sight dizziness And disorientation in space. This person can not correctly assess the distance. Maybe much headache, nausea, sometimes marked.
If a person complains about the doctor that was seeing double, in the process of diagnosis is determined, what kind of doubling occurs in the patient - upright . Horizontal or diagonal . It depends on what kind of damage to the eye muscles is observed. Depending on the type of ghosting is noted for its orientation. If direct eye muscle paralysis, the person sees the objects that are placed in parallel, and if there is a paralysis of the oblique muscles, the objects are seen each other. At the same time there is often only one type of diplopia. If, for example, a person sees double vertical, diagonal doubling it thus can not be observed.
In some cases, there may be double vision in one eye. This phenomenon is associated with subluxation of the lens, so that the rays passing through the lens of the affected are scattered. However, this type of milking in the eyes diagnosed relatively rarely. If any of the one eye is diagnosed monocular diplopia , With the defeat of the functions of both eyes - binocular diplopia . Binocular diplopia often contributes to the development of a person temporary or permanent strabismus . If a person has been monocular diplopia, closing his eyes healthy is an image of two images.
If the patient is twofold vision, objects appear to him not only forked, but blurred, indistinct. There may be some ephemeral image when going head movement, the image as it flows.
People who occasionally doubles the image in the eyes, it should be borne in mind that accurately estimate the distance to a particular subject if they are the manifestation of this symptom can not. Therefore, you should pay special attention and caution, moving through the streets. Especially careful to be people on the carriageway.
Why seeing double?
The main reason for existence of double vision - a violation of binocular movement. This may be due either to the defeat of the eye muscles or neurological factors. Sometimes the cause of ghosting is a violation of the dislocation of the eyeball in the eye socket. Just say why double vision, is possible only after a more detailed examination and diagnosis.
This symptom may occur in humans with various diseases. First of all, it's a variety of diseases associated with damage to the nervous system. It stroke Brain tumor, meningitis . multiple sclerosis and others. Double vision observed in patients vascular aneurysms . vasculitis , In victims who received traumatic brain injury .
Seeing double may, at the disorders of the peripheral nervous system. With the defeat of the linked neuritis . compression of the oculomotor nerves tumors . Nervous system determines the perception of reality and the response to it. Consequently, with the defeat of the nervous system or the wrong person perceives reality, or has indicated an inadequate response to it. With the development of Diabetes a person as one of the symptoms is often a double vision.
Another reason why a person is constantly seeing double, is a violation of the tone of the eye muscles or defeat. Paralysis or paresis these muscles observed in patients myasthenia . myositis , Edema, and others.
If the orbit is formed tumor, it gradually shifts the eyeball from the position in which it is to be located in the norm. As a consequence, there is double vision.
This symptom may occur after a person is injured or traumatized eye tissues that surround the eye. If after hitting double vision, it demonstrates a shift in the eyeball, which occurs due to the formation of edema, or in violation of wall sockets.
Ghosting is typical of people who took intoxication associated with botulism , Chemical poisoning, alcohol.
Often the patient dizzy and seeing double when severe fever, which is celebrated during the acute respiratory infections . Flu .
Monocular diplopia is most often associated with structural features of the eye. For vision, usually it is less dangerous. Development of monocular diplopia is often associated with damage to the cornea, with the displacement of the lens, cataracts . astigmatism , Refractive errors. Less doctors diagnosed psychogenic The simulated or diplopia.
How to get rid of the double vision?
What if the double vision, one must be sure to ask a specialist. Treatment of double vision invariably associated with treatment of the underlying disease That is, only to get rid of the symptom will not work . If one observes the sudden onset of this phenomenon and feels strongly that he sees double, be sure to call the emergency aid . The fact that the reasons for which this symptom appears, can be severe . In the acute form of the disease associated with the twins, are dangerous to health . Only their timely treatment can prevent severe consequences . When double vision should consult with an ophthalmologist, neurologist and endocrinologist . To establish a diagnosis, always held eye exam . If necessary, designate holding the eyeballs ultrasound, computed tomography of the head . Depending on the diagnosis, the treatment is carried out . Typically, surgery is indicated for disorders of the eye muscle groups . During the surgery may change in muscle length, tendon is sutured if necessary to keep the right position of eyes . In most other diseases treatment practiced medicine .
During treatment to reduce discomfort to the patient can be carried out so-called prismatic correction . A person must wear specially made for him glasses with prismatic lenses. Such lenses bring together points of view, whereby ghosting is observed. However, keep in mind that when wearing these glasses decreased visual acuity.
To improve visual acuity is recommended three times a day to perform special exercises. However, experts warn that the exercises are effective only when partial diplopia . The full treatment regimen when diplopia doctor prescribes individually.
