Convergence paralysis or spasm
Introduction
Introduction Eyeball convergence function paralysis or paralysis is more common in the pineal somatic tumor eye, in addition to the eye can not be seen, but also accompanied by changes in pupillary photoreaction, eyeball convergence function paralysis or paralysis, nystagmus. The damage around the aqueduct (including the front of the aqueduct and the posterior part of the third ventricle) is impaired. In the somatic cell tumor, the tumor compresses or infiltrates the pineal region and its adjacent structure, causing damage to the nervous system, and the eyeball converging function is paralyzed or paralyzed. Sylvian aqueduct syndrome can not be seen in addition to the eyeball. It is also accompanied by a change in pupillary photoreaction. Eyeball convergence is paralyzed or paralyzed. Eyeball tremors. Look at the vascular abnormalities, whether there is a problem with blood pressure and blood sugar.
Cause
Cause
The cause of eyeball convergence is paralyzed or paralyzed:
In the pineal somatic tumor, the tumor compresses or infiltrates the pineal region and its adjacent structure, causing damage to the nervous system, and the eyeball converging function is paralyzed or paralyzed.

Eyeball convergence function paralysis or paralysis examination diagnosis:
More common in pineal somatic tumors, neurological damage symptoms, eye signs: quadrilateral superior juvenile syndrome (Parinaud syndrome) and Sylvian aqueduct syndrome. Tumor destruction of the upper mound and the cap area cause eye movement disorders. Can't look up on both eyes. Pupil light reflects obstacles. Parinaud syndrome usually only has two eyes that cannot be seen. Caused by compression or destruction of the tumor by the bundle of cortical caps. The latter half of the hill is damaged. Then the two eyes can't be seen. Sylvian aqueduct syndrome can not be seen in addition to the eyeball. It is also accompanied by a change in pupillary photoreaction. Eyeball convergence is paralyzed or paralyzed. Eyeball tremors. The damage around the aqueduct (including the front of the aqueduct and the posterior part of the third ventricle) is impaired.
Diagnosis
Differential diagnosis
Eyeball converging features paralyzed or confusing symptoms:
Differential diagnosis should pay attention to distinguish tumors located outside the pineal region, such as meningioma hemangioma; adjacent sites such as brain stem cerebellum and other tumors; pineal cysts and other diseases and pineal tumors are mainly based on Film degree exam.
