TM3-1 Idiopathic intracranial hypertension: consensus guidelines on investigation and management

Objectives The aim was to capture interdisciplinary expertise from a large group of clinicians, reflecting practice from across the UK and further, to inform subsequent development of a national consensus guidance for optimal management of Idiopathic Intracranial Hypertension. Design Consensus guideline critically reviewed by the Association of British Neurologists, British Association for the Study of Headache, the Society of British Neurological Surgeons and the Royal College of Ophthalmologists. Subjects An initial UK survey of attitudes and practice in IIH was sent to a wide group of physicians and surgeons. Methods Between September 2015 and October 2017 a specialist interest group including neurology, neurosurgery, neuro-radiology, ophthalmology, nursing, primary care doctors, and patient representatives met. A comprehensive systematic literature review was performed to assemble the foundations of the statements. Results Over twenty questions were constructed: One based on the diagnostic principles for optimal investigation of papilloedema and twenty-one for the management of IIH. 3 main principles were identified: to treat the underlying disease; to protect the vision and to minimise the headache morbidity. Statements presented provide insight to uncertainties in IIH where research opportunities exist. Conclusions In collaboration with many different specialists, professions and patient representatives we have developed guidance statements for the investigation and management of adult IIH.
