The value of ICT is important in diagnosis of the diseases of the eye and orbit Methods for direct measurement of intracranial pressure (ICT) are exact, but they are invasive and there is some risk of infection and damage of the tissue. Currently there are 2 valid indirect methods of mesurement of IKT. Digital Ophthalmodynamometry (D-ODM) and Transcranial Doppler ultrasonography (TDU). D-ODM is a ...

Objective: The cribriform plate is a threshold of the intraocular pressure (VOT) and of the intracranial pressure (IKT). The difference between the VOT and IKT is referred to as translaminar gradient (TLG). The goal was to evaluate the Glaucoma progression (visual field, fundus examination, HRT) with / without topical anti-glaucomatous therapy) in relation to the TLG. Patients and methods: the sig...

Purpose: The problem of optic disc drusen (ODD) has been described in detail in several publications. However, less attention has been devoted to real haemodynamic parameters (HP) in ODD. It has been clinically demonstrated that the occurrence and progression of changes in the visual field in ODD are closely linked with the haemodynamics of the vascular supply of the eye – the optic nerve. ODD may...

Carotid-cavernous fistula (CCF) is an abnormal communication - vascular connection between arteries and veins in the cavernous sinus. Classification according to etiology is traumatic vs spontaneous. According to blood flow rate per high flow vs low flow fistula. According to anatomy of direct vs indirect: Direct (direct) CCF arises through direct communication between the internal carotid artery ...

The authors present a relatively rare finding of pathological changes in the visual field, the emergence of homonymous hemianopia, in connection with trauma and paradoxical embolism in a subsequently diagnosed open foramen ovale in a 56-year-old otherwise healthy patient. Cardiac source of embolism is a significant etiology of vascular embolization. The important group is the so-called paradoxical...
