external ocular vertigo
Introduction
Introduction Dizziness is the general term for dizziness and dizziness. It is glare with vertigo, unclear vision and darkness and darkness. It can be stunned by the rotation of the object, or if it can not stand as a dizzy, because the two often meet at the same time. Eye-induced vertigo: non-motor illusion vertigo, mainly manifested as instability, increased when the eye is excessive, and relieved after closed eyes. Dizziness lasts for a short period of time. When you look at the moving objects, you will get worse. After you close your eyes, you will ease or disappear. Often accompanied by blurred vision, decreased vision or double vision. Visual acuity, fundus, and eye muscle function tests are often abnormal, and the nervous system has no abnormalities.
Cause
Cause
Causes of external eye-derived vertigo:
If the eye muscle paralysis produces double vision, pay attention to flying fast or standing on a cliff, etc., causing dizziness and dizziness.
There are many kinds of diseases that cause dizziness, and there are about hundreds of diseases that can cause dizziness. The causes of different diseases are also different. According to the different lesions, it can be divided into two categories: peripheral vertigo and central vertigo. Central vertigo is caused by brain tissue and cranial nerve diseases, such as acoustic neuroma and cerebrovascular disease, accounting for about 30% of the total number of patients with vertigo. Peripheral vertigo accounts for approximately 70%, and most peripheral vertigo is associated with our ear disease. Peripheral vertigo is often accompanied by cochlear symptoms (hearing changes, tinnitus) and autonomic nervous system symptoms such as nausea, vomiting, and cold sweat. Some diseases can be recurrent vertigo and relieve themselves.

Examination and diagnosis of external eye-derived vertigo:
1. The nature of vertigo should be clear: peripheral vertigo, nystagmus has a fixed direction; paroxysmal, sporadic or severe vertigo attacks, no abnormalities in the intermittent period suggest peripheral sexual causes; unilateral deafness with tinnitus is a peripheral cause Unilateral deafness with tinnitus is a reliable marker of peripheral neuropathy. Central vertigo, nystagmus direction is not fixed; persistent vertigo or imbalance, accompanied by nystagmus and gait disturbance, suggesting central nervous system diseases; diplopia, unclear articulation, ataxia, unilateral palsy Etc. also suggests central lesions.
2. The vestibular function test and electrical test are more valuable. The cranial radiograph, EEG, cerebrospinal fluid examination, Cr, hmI, and cerebral angiography can further clarify the cause.
3. Combined with the clinical features of the above diseases, the diagnosis is finally confirmed.
Diagnosis
Differential diagnosis
Differential diagnosis of external eye-derived vertigo:
1, cerebrovascular vertigo: summer and winter season due to increased blood viscosity, prone to various cerebrovascular accidents, leading to cerebral vasospasm. Should pay attention to drinking more water, do not suddenly change the position, such as slamming when going to the toilet at night, are prone to cause cerebral vascular dizziness. Once it happens, you should go to the hospital as soon as possible. After the diagnosis, you can give appropriate vasodilator drugs, anti-platelet aggregation drugs (such as aspirin), anticoagulant drugs.
2, brain tumor vertigo: the incidence of such vertigo is more slow, the initial symptoms are lighter, not easy to find. For the gradually appearing mild vertigo, if accompanied by unilateral tinnitus, deafness and other symptoms, or other signs of damage to the adjacent cranial nerves, such as numbness and sensation of the side of the disease, peripheral facial paralysis, etc., should go to the hospital as soon as possible, clear Diagnosis, early surgical treatment.
3, cervical vertigo: should pay attention to the position of work and study, should be appropriate after the long time desk work. The pillow is highly suitable and the bolster cannot be too high to cause cervical vertigo. Rehabilitation methods are often used in the treatment, such as cervical vertebrae jaw sling traction, massage manipulation, acupuncture, etc., which requires serious surgery.
4, for other diseases caused by dizziness, such as endocrine vertigo, hypertensive vertigo, eye-derived vertigo, should actively treat the primary disease, such as blood pressure control, treatment of ophthalmic diseases, based on the recovery of the primary disease, vertigo can be naturally relieved .
5, neurological vertigo: for vertigo caused by mental factors, the patient should first relieve the anxiety and anxiety, can be given appropriate anti-anxiety or anti-depressant drugs, but to avoid long-term use of sedative drugs, so as not to increase drug tolerance Sex and dependence.
