Paralytic strabismus is caused by paralysis or paresis of one or more oculomotor muscles, caused by various reasons: trauma, tumor, infection, etc.
It is characterized primarily by the absence or restriction of the mobility of the squinting eye towards the paralyzed muscle. Subjective tive disorders paresis or paralysis of one of these muscles expressed as diplopia (double vision).
Diplopia – very painful for the patient Destroy GUSTs, which complicates the orientation in space, it causes dizziness. This disorder disappears immediately if you close one eye. It should be noted that with prolonged paralytic strabismus, the image from the squinting eye in the cerebral cortex is suppressed and diplopia is not felt.
NISTAGM.
Nystagmus (trembling of the eye) – involuntary rhythms cal movement of the eyeballs. Nystagmus can be hori zontally, vertical, rotational, and other pendulum.
Etiology.
The cause of nystagmus can be various changes in the eyes of a congenital or acquired (in early childhood) nature, leading to a decrease in visual acuity, as well as various central nervous system lesions, usually of a congenital nature.
Nystagmus usually does not cause anxiety to patients, but they are very suffering from poor vision. With age, a decrease in the severity of nystagmus is possible.
TREATMENT.
- However, even with the impossibility of its establishment or elimination expedient different manifestations pleoptic and pharmacological treatment (assignment vitamins, shpy, tissue therapy installation 1% mezatona solution , etc.), The benefit of giving that can improve visual function, and several reduced the amplitude nystagmus .
In some cases, mainly during horizontal nystagmus, it is possible to achieve a favorable outcome of the operations on glazodvigatel muscle activation.
TREATMENT.
- Physiotherapy is often used locally with success .
- In the absence of the effect of conservative treatment, surgical is used . In principle, as with friendly strabismus, it consists in strengthening the affected muscle or weakening the antagonist. Often have to resort to complex plastic vmesha stances on several muscles. The issue about the indications and the operation time is achieved together with the corresponding experts (nevropatolo gom, and a oncologist al.).
- To remove diplopia, prismatic glasses are prescribed.
