“…In the case of elevated ICP, Sajjadi and colleagues9 theorize that cerebrospinal fluid (CSF) encasing the optic nerve head may communicate this elevated pressure into the eye. There is neuroimaging evidence of posterior globe compression due to elevated ICP,17 but compression of the globe by increased ICP has not been shown to elevate IOP in any study reported to this time. No study except that by Sajjadi and colleagues9 has shown a clinically useful correlation between elevated ICP and IOP 2–8.…”

“…6 Posterior globe flattening is considered by some authors to be the sine qua non neuroimaging sign of PTC and can be seen on both CT and MR imaging but may be a more subtle finding subject to interpretation. [66][67][68] Globe flattening may be explained by the direct correlation between elevated ICP and IOP via the transmission of elevated CSF pressure through the subarachnoid space, extending through the ONS to the posterior globe. 24 One possible confounding explanation for posterior sclera flattening is its detection in the context of ocular hypotony; however, this condition is more rare, and this neuroimaging finding is more likely to be indicative of intracranial hypertension.…”

“…A avaliação radiológica é fundamental no paciente com HII, no intuito de descartar a presença de massas intracranianas ou ventriculomegalia. Entretanto, os exames neurorradiológicos podem também contribuir com o diagnóstico da HII (21)(22) ao detectar achatamento da esclera posterior, sela túrcica vazia, alargamento do espaço subaracnóideo perióptico e deslocamento vertical do nervo óptico, que ocorrem em 80%, 70%, 45% e 40% dos pacientes, respectivamente (21) .…”

“…O efeito colateral mais comum da acetazolamida, além de principal motivo para suspensão do tratamento, é a parestesia das extremidades dos membros. Pacientes que necessitam de altas doses para atingir o efeito terapêutico e os que se tornam refratários ao efeito da acetazolamida necessitam de uma alternativa terapêutica (20)(21)(22)(23) .…”
