Bariatric Surgery as a Viable Treatment for Idiopathic Intracranial Hypertension: a Case Series and Review of Literature.

Idiopathic intracranial hypertension is a significant cause of preventable blindness. Patients suffer from debilitating headaches, pulsatile tinnitus, nausea, vomiting, photophobia and radicular pain. At this rate, treatment cost will increase to 462.7 million pounds sterling annually by 2030. Weight loss is the only proven disease-modifying therapy for reversal of idiopathic intracranial hypertension. Bariatric surgery leads to superlative weight loss and reversal of related comorbidities. The case series and literature review aim to raise awareness of bariatric surgery as a safe and effective treatment modality for idiopathic intracranial hypertension. The literature review comprises three systematic analysis and one randomised control trial which were identified after a PubMed search. In the case series, we have included four patients with a preoperative diagnosis of long-standing idiopathic intracranial hypertension. They were referred to our department for bariatric surgery by the neuro-ophthalmologist between January and December 2018. They were followed up for 2 years after bariatric surgery. All four patients were women with a mean age of 34 years. Mean body mass index reduced from 47.3 kg/m Bariatric surgery is a safe and effective method of treating idiopathic intracranial hypertension. It is superior compared to medical management and cerebrospinal fluid pressure reducing procedures which have high rates of recurrence.
