Concomitant edema


Congestive discs of the optic nerves (ZDZN)Ophthalmoscopy is the edema of the DZN, which arises from the increase in intracranial pressure (ICP). Among the most common causes of intracranial hypertension should be called volumetric formation of the brain, hydrocephalus, benign intracranial hypertension, craniocerebral trauma. Since the description of the ophthalmoscopic picture of the ZDZ von Graefe in 1860-1866. the researchers attached great importance to the anatomical features of the optic nerve in the ZDZN. It is known that after leaving the scleral canal through the trellis plate into orbit, the visual fibers form into the trunk of the optic nerve. The orbital part of the trunk of the optic nerve is covered all over by three shells: solid, arachnoid and soft. Shells of the optic nerve form the so-called subshell space: subdural - slit-shaped and subarachnoid - of large dimensions. These spaces communicate with the same spaces of the brain. An increase in cerebrospinal fluid pressure in the subshell space of the brain in patients with intracranial hypertension causes an increase in the pressure in the subshell space of the optic nerve, which leads to its expansion, which was found in a pathomorphological study in patients with ZDZN. The development of modern technologies allowed lifetime to study and quantify various structures of the eye and orbit, including the optic nerve. These modern imaging methods include magnetic resonance imaging and ultrasound (ultrasound). The purpose of this work is to evaluate the possibilities of ultrasound of the optic nerves in patients with intracranial hypertension, to compare the results with the data of the neurological examination and their dynamics after surgical treatment.
