- Background and purpose We previously reported that certain optical coherence tomography (OCT) measures were sensitive and reliable in identifying idiopathic intracranial hypertension (IIH). This prospective study aimed to define OCT measures that allow differentiation of IIH with and without papilledema, thereby helping clinical decision-making. Methods Eight patients with IIH with papilledema, nine without papilledema and 19 with other neurological diseases were included. OCT measures were obtained before lumbar puncture and within 2 h, 1, 3 and 6 months after lumbar puncture with cerebrospinal fluid (CSF) removal. Results All patients with papilledema had increased retinal nerve fiber layer (RNFL) thickness and elevated CSF pressure. All patients without papilledema had normal RNFL but elevated CSF pressure. After CSF removal, reduced RNFL thickness was registered in all eight patients with IIH with papilledema. No significant change in RNFL thickness after CSF removal was observed in IIH without papilledema or in patients with other neurological diseases, although reduced CSF pressure was documented. RNFL thickness tended to be normal in patients with IIH with papilledema at 3-6 months after CSF removal. All patients with IIH showed increased rim area and rim thickness, but reduced optic cup volume regardless of RNFL thickness or papilledema. Conclusions Retinal nerve fiber layer thickness is sensitive for monitoring acute IIH and evaluating treatment effect. Increased rim area and rim thickness and decreased optic cup volume are reliable parameters that indicate persistently increased CSF pressure and risk of relapse. OCT measures are sensitive and reliable for diagnosing subtle IIH even in the absence of papilledema.

- Introduction: The purpose of this study was to examine patients experiences of vagal nerve stimulation (VNS) with a special interest in patients with cognitive deficit (CD). Materials and Methods: An open, retrospective study was conducted on 82 patients with pharmacoresistant epilepsy, who were treated with VNS for at least 10 months. Based on the inability to live independently, they were divided into two groups: patients with cognitive deficit (CD group) and patients without cognitive deficit (non-CD group). A specially designed questionnaire was used for semi-structured interviews about patients experiences of VNS treatment. Results: Approximately one-third described a continuous reduction of seizure frequency of 50% or more and were regarded as responders. Fewer subjects in the CD group were responders than in the non-CD group. Approximately one-third of all subjects had no positive effect of VNS treatment. More CD patients described additional improvements and the most common were milder seizures and improved alertness. The most commonly reported adverse effect was hoarseness. Discussion: VNS treatment in patients without CD had better effect on seizure frequency reduction than in patients with CD, but many patients with CD reported other benefits from the treatment.
