The investigator working hypothesis is an impairment of the cerebral venous drainage in IIH compared to the circulation observed in healthy volunteers considered as the reference. The research will focus on adult patients referred to the imaging department for intracranial hypertension assessment.
After signing the informed consent form, potential subjects will be assessed for eligibility, including eliciting medical and neurologic history, measurement of best-corrected visual acuity, visual field testing, ophthalmoscopy with optic disc edema grading, physical examination, and Optical
Numerous authors have described optic disc edema, globe flattening, choroidal folds which were thought to be part of the well-defined but still idiopathic syndrome of idiopathic intracranial hypertension.

Antiretroviral therapy (ART) has dramatically reduced the death rate from AIDS and improved the quality of life of many HIV-infected individuals. However, ART does not eradicate HIV as demonstrated by the rapid return of viremia whenever treatment is interrupted. The possible long-term toxicity
Evidence from initial analysis of 5 SNPs in the one-carbon metabolism pathway suggests that one-carbon pathway genes may predict risk of ocular changes and possible vision impairment during and after long-duration space flight. It is not precisely known whether it is these particular genes, or a
The craniospinal cavity is enclosed by a rigid, non-compressible bone and thus has a constant volume. It is filled with soft tissue (brain, spinal cord and connective tissue), cerebrospinal fluid (CSF) and circulating blood. Intracranial pressure (ICP) is the pressure of the fluid that bathes the
