A 15-year-old girl presented with a unilateral sixth nerve palsy and papilledema following a severe headache. MR imaging showed thrombosis of the superior sagittal sinus and proximal right transverse sinus that were attributed to oral contraceptive use after a coagulation workup was negative. Systemic anticoagulation caused a hemorrhagic papillopathy in both eyes, raising the question as to whether anticoagulation should be discontinued. Diagnostic and management issues regarding cerebral venous sinus thrombosis with secondary intracranial hypertension are discussed...

Idiopathic intracranial hypertension is characterized by raised intracranial pressure (ICP) without any underlying pathology, presenting with (IIH) or without papilledema (IIHWOP). Headache, often on daily basis, is the most frequent symptom. Among audiovestibular symptoms, tinnitus and dizziness are commonly reported, while vertigo and hearing impairment are infrequent reports. Endolymphatic hydrops (ELH) is the typical histopathologic feature of Ménière disease, a condition featured by episodes of vertigo, dizziness, fluctuating hearing loss, tinnitus, and aural fullness...

REVIEW
M-B Rougier
This article will review the current standard of care in the diagnosis and management of bilateral optic disc edema. Two emergent conditions must be considered first: secondary intracranial hypertension (cerebral tumor, cerebral thrombophlebitis…) and arteritic ischemic optic neuropathy (or giant cell arteritis). Having ruled out these two diagnoses, the management follows various steps in order to: (i) rule out pseudo-edema, and (ii) determine the underlying cause of the edema: papilledema, non-arteritic ischemic optic neuropathy or papillitis...

Heather E Moss
Visual function is an important parameter to consider when managing patients with papilledema. Though the current standard of care uses standard automated perimetry (SAP) to obtain this information, this test is inherently subjective and prone to patient errors. Objective visual function tests including the visual evoked potential, pattern electroretinogram, photopic negative response of the full field electroretinogram, and pupillary light response have the potential to replace or supplement subjective visual function tests in papilledema management...

BACKGROUND: The conventional treatment for idiopathic intracranial hypertension involves weight loss, steroids, diuretics, and/or serial lumbar punctures; however, if the symptoms persist or worsen, surgical intervention is recommended. Surgical options include cerebrospinal fluid diversion procedures, such as ventriculoperitoneal and lumboperitoneal shunts, and optic nerve decompression with nerve sheath fenestration. The latter can be carried out using an endoscopic approach, but the outcomes of this technique have not been firmly established...
