Diagnostic value of optical coherence tomography for intracranial pressure in idiopathic intracranial hypertension.
Idiopathic intracranial hypertension (IIH) is a condition of raised intracranial pressure (ICP) in the absence of space-occupying lesions or other known etiology. It primarily affects young obese females, and potentially causes permanent visual loss due to papilledema and secondary optic atrophy. The aim of this study was to evaluate the diagnostic value of optical coherence tomography (OCT) as a marker for CSF opening pressure in patients with idiopathic intracranial hypertension (IIH). ⋯ Increased peripapillary retinal thickness measured by OCT is associated with increased ICP in newly diagnosed IIH patients. OCT may thus serve as a valuable supplement to subjective assessment of papilledema in patients suspected of having IIH. In long-term IIH patients who have previously been treated, OCT appears to be of limited value in predicting ICP.
