visual disturbances, which are characterized by the doubling of the image of any visible object that is the result of a deviation of the visual axis in one eye. The reason for the double vision occurs when the object that is seen, is not the Central hole, and at another part of the retina.
Diplopia is always evolving as a disorder of binocular vision (binocular diplopia). If you close one eye, then the effect of the doubling will stop immediately. But very rarely it happens sometimes that occurs and monocular diplopia. Basically this occurs when related eye diseases.
Usually, diplopia occurs and is the result of disorders of the Central division of the visual channel or a consequence of the pathology of muscular equilibrium, that have evolved due to the weakening of the function of the affected eye. Are these symptoms of diplopia to shift his eyes to the side or restricting its mobility.
In addition, the development of the disease can provoke pathologic or neurogenic processes in the eye. Diplopia develops with complete paralysis or weakening of the functions of the oculomotor muscles.
Causes of diplopia
- pathology of the orbit, which lead to the displacement of the eyeball
- injuries of the eye orbit, caused by infringement of the eye muscle, or after fracture of the lower wall of the eye
- hematoma or tumor, which is limited to eye movement or fixation
- when head injuries with damage to the oculomotor nerve
- with an aneurysm of the carotid artery.
- double vision
- constant dizziness
- the difficulty in assessing the location of objects.
The nature of the development of diplopia depends on the localization process. For example, if struck by the direct muscles, the person is parallel to the double vision of objects, if oblique, on the contrary, are perpendicular.
If parallel person sick of an infectious or other diseases (tumors,
fractures, vascular diseases of the brain), the overall picture of diplopia combined with the symptoms of the disease.
Treatment diplopia is the immediate identification of the cause and source of diseases and their elimination. In some severe cases, needs urgent treatment of the disease. For example, when
patient must be immediately hospitalized. In other cases the reason for hospitalization is only heavy for any serious condition of the patient.
