Symptoms of pendulum nystagmus?

summary

Patients with nystagmus can swing in horizontal direction, vertical direction and rotation direction, among which horizontal type of nystagmus is the most common. The direction of patients' nystagmus is usually expressed in the direction of fast phase, and there will be compensatory movement to return to normal fixation position. Ocular tremor is often caused by diseases of the extraocular muscles of the visual system, labyrinth of the inner ear and central nervous system. Generally speaking, the disease is not an independent disease, but the clinical symptoms of some diseases, treatment should be based on the cause of treatment.

Symptoms of pendulum nystagmus?

According to the causes and symptoms of ocular tremor, it can be divided into ocular tremor caused by difficulty in fixation reflex formation, including physiological fixation ocular tremor caused by oblique, visual dynamic and recessive ocular tremor, pathological fixation ocular tremor caused by blindness, amblyopia and occupational ocular tremor, and vestibular, visual and occupational ocular tremor Central and congenital ocular tremor.

When the patient has the disease. When the patient's eyeball slowly turns to the other side, to a certain extent, it will suddenly jump back. This is the beating performance of the patient's eyeball. This tremor will have the symptoms of chronic and fast phase. The physiological phase is chronic and fast phase is the corrected movement of slow phase.

Some patients' eyeballs will have swing type reaction. At this time, the swing of patients' eyeballs is like a pendulum, and there is no distinction between fast phase and slow phase. The speed of eye movement is equal to the amplitude of sense of movement. Black eyes and vulnerable patients often have this kind of performance. Patients with ocular tremor can also be divided into recessive and dominant ocular tremor. In the examination and identification of this disease, the patient is often asked to watch the eye movement when it moves with the direction of the examiner's finger. Some patients need to cover their eyes for examination.
