Chiasma syndrome is a condition in which the function of the optic chiasm, which is located in the splenic angle of the brain, is disrupted. The optic chiasm is a key element of the visual system as it is responsible for sending signals from the eyes to the brain.
The main symptom of chiasma syndrome is decreased visual function, as well as impaired visual field. In this case, patients may complain of double vision, color vision disorder, and impaired visual acuity.
Chiasma syndrome can occur for various reasons. One of the most common is a brain tumor that compresses the optic chiasm. In addition, chiasm syndrome can occur with inflammatory diseases of the brain, pituitary gland, hypothalamus, as well as with head injuries.
Diagnosis of chiasm syndrome is carried out using computed tomography or magnetic resonance imaging of the brain. If a brain tumor is detected, surgery may be required to remove it. For other causes of chiasma syndrome, treatment is aimed at eliminating the underlying disease.
In general, chiasma syndrome is a serious disease that requires timely diagnosis and treatment. At the first signs of visual impairment, you must consult a neurologist for diagnosis and prescribing appropriate treatment.
Chiasma syndrome. On March 2-2, 2019, the date of the International Day of Person with Chiasmus Syndrome became known. According to the International Classification of Diseases, 11th revision (ICD-11), the systematic name of the nosology is as follows: “SINUS CEREBROSPINALIS No. ....”.
Chiasm syndrome (in other words, cerebral chiasm) is a congenital pathology of the optic chiasm, which is an incomplete cerebral chiasm of fibers. This anomaly is a form of intermediate visual dysfunction, in which there is a disruption in communication between the eyes and the visual centers of the brain. Its main symptoms are sensitivity to light associated with visual impairment.
The optic chiasma is located in the center of the intracranial space and has two eyes of entry and exit or exit openings. It plays an important role in regulating visual images, directing light first in one direction and then in the other. In some people, however, a small gap or incomplete chiasm may develop at the level of the chiasm. It is not a disease in itself, but can cause problems with vision and other senses.
