Neuro-ophthalmologists frequently care for patients with idiopathic intracranial hypertension (IIH), although many questions remain unanswered regarding its diagnosis, pathogenesis, and treatment. The Friedman-Jacobson criteria for the diagnosis of IIH specify lumbar puncture (LP) opening pressure values that are largely based on experience with little supporting normative data. Until recently, there ...

Intracranial pressure (ICP) is the pressure within the intracranial space. Intracranial hypotension is a clinical syndrome in which low cerebrospinal fluid volume (CSF) results in orthostatic headache. Severe cases can result in nausea, vomiting, photophobia, and, rarely, decreased level of consciousness and coma. CSF opening pressure can be within the ...

Increased intracranial pressure occurring after severe traumatic brain injury is a common and potentially devastating phenomenon. It has been clearly demonstrated that increased intracranial pressure that is refractory to initial medical measures is a poor prognostic sign. Current optimal management is based on a sequential, target-driven approach combining both medical ...
