    Management of Peripapillary Choroidal Neovascular Membrane in Patients with Idiopathic Intracranial Hypertension
    (Wolters Kluwer, 2019-12) Ozgonul, Cem; Moinuddin, Omar; Munie, Metasebia; Lee, Michael S.; Bhatti, M. Tariq; Landau, Klara; Van Stavern, Gregory P.; Mackay, Devin D.; Lebas, Maud; DeLott, Lindsey B.; Cornblath, Wayne T.; Besirli, Cagri G.; Ophthalmology, School of Medicine
    Objective: To report the clinical features and treatment outcomes of patients with peripapillary choroidal neovascular membrane (CNVM) secondary to idiopathic intracranial hypertension (IIH). Methods: Retrospective, multicenter chart review of patients diagnosed with peripapillary CNVM in the course of the treatment and follow-up of IIH. Results: Records were reviewed from 7 different institutions between 2006 and 2016. Ten patients (13 eyes) with a diagnosis of IIH and at least 3 months of follow-up developed CNVM. Three of the total 10 patients developed bilateral CNVM. The mean time from the diagnosis of IIH to CNVM diagnosis was 41 months. Mean follow-up period was 8 months after diagnosis of CNVM. All patients were treated with acetazolamide for IIH. Seven eyes were observed, and 6 eyes were given anti-vascular endothelial growth factor (anti-VEGF) injections, including bevacizumab, ranibizumab, and aflibercept. All CNVMs regressed with subretinal fibrosis, and visual acuity improved in most patients. Papilledema resolved in only 1 eye, while the other 12 eyes had persistent papilledema at last follow-up. Conclusions: Peripapillary CNVM, a rare complication of IIH, often resolves spontaneously with treatment of IIH. In vision-threatening and/or persistent cases, intravitreal anti-VEGF treatment may be a safe and effective therapeutic option.

    Transverse venous sinus stenting for idiopathic intracranial hypertension: Safety and feasibility
    (SAGE Publications, 2018-10) Koovor, Jerry ME; Lopez, Gloria V.; Riley, Kalen; Tejada, Juan; Radiology and Imaging Sciences, School of Medicine
    Purpose Transverse sinus stenosis is commonly seen in patients with idiopathic intracranial hypertension. It is not clear whether it is the cause or the result of idiopathic intracranial hypertension. Stenting for idiopathic intracranial hypertension has been carried out in several prior series. Our goal was to evaluate the clinical and imaging follow-up results of patients with idiopathic intracranial hypertension that underwent stenting for this condition at our center. Materials and Methods We reviewed the clinical, venographic and follow-up imaging data in patients who underwent elective transverse sinus stenting during the period from 2011 to 2017. Results In total, 18 patients with idiopathic intracranial hypertension were identified. The mean lumbar cerebrospinal fluid opening pressure recorded was 408 mmH20. Overall, 16 patients met the inclusion criteria and underwent transverse sinus stenting. At venography, the mean pressure gradient across the dominant transverse sinus stenosis was 21 mmHg. The pressure gradient immediately after stenting in all of those measured was negligible. Following stenting, headaches improved in 10 of the 16 cases, with persistent headaches in four patients, one of which had persistent baseline migraines. All cases showed resolution of the papilledema on follow up. Follow-up imaging with computed tomography venography showed that the stents remained widely patent. The follow up in clinic was done for a mean period of 35.5 months. Follow up with computed tomography venography was done for a mean of 10.3 months. Conclusion Venous sinus stenting is a safe and effective procedure. It relieves papilledema in all cases and improves headaches in most cases.

    Unusual causes of papilledema: Two illustrative cases
    (Scientific Scholar, 2013-04-18) Nguyen, Ha Son; Haider, Kathryn M.; Ackerman, Laurie L.; Ophthalmology, School of Medicine
    Background: Neurosurgeons are frequently among the first physicians asked to evaluate patients with papilledema, and the patient is often referred with the implication that they may require shunting. After an initial evaluation to exclude potential neurosurgical emergencies, the physician should carefully consider various etiologies of papilledema to prevent unnecessary neurosurgical operations. Case Description: The authors report two illustrative cases of unusual causes of papilledema: Anemia and leukemic infiltration of the central nervous system. In each case, a complete blood count provided clues for the diagnosis. A review of the literature is also included. Conclusions: Both patients responded to medical management/treatment of the underlying disease and did not require neurosurgical operative intervention. Papilledema may be caused by other etiologies besides increased intracranial pressure. The authors present two unusual cases leading to papilledema and provide an outline for the workup of these conditions.
