Intracranial hypertension as a risk factor for central serous chorioretinopathy

Purpose: to assess blood supply disorders at the level of the vessels of the eyeball, intracranial vessels and vertebrobasilar basin in patients with central serous chorioretinopathy (CSC) and to compare the revealed changes with the clinical picture of the disease. Material and Methods. An ophthalmological examination of 10 patients with CSC was performed: in addition to standard methods, it included optical coherence tomography (OCT) of the optic nerve disc, ultrasound B-scanning of the eyeball, perineural and retrobulbar space. Four patients additionally underwent magnetic resonance imaging (MRI) of the brain and cervical spine, ultrasound Dopplerography of extraand intracranial vessels. Results. An OCT of the optic nerve disc revealed an expansion of the subarachnoid space. According to the ultrasound B-scan data, patients with CSC showed a moderate expansion of the perineural space of the optic nerve and a significant expansion of the orbital vessels. The MRI showed signs of internal hydrocephalus. Based on ultrasound Dopplerography of extraand intracranial vessels, a conclusion was made about the signs of intracranial venous hypertension. Conclusion. Disorders of blood flow in the eye veins, vertebral arteries, along the transverse sinuses were revealed, signs of external and internal hydrocephalus were found. The role of pathological changes of central genesis in the development of CSC has been established. Interdisciplinary research and extended therapeutic measures are required.
