Show Neuro-Ophthalmology News Section Editors: Kathleen B. Digre, MD Meagan Seay, DO International Headache Society September 8–12, 2021 T he International Headache Society held a virtual CONGRESS September 8-12, 2021, along with the European Headache Federation that was supposed to be held in Berlin, Germany, but because of the Covid-19 pandemic and travel restrictions, we had an exciting meeting on a Zoom platform. Nevertheless, the meeting was well attended and had excellent important lectures for neuroophthalmologists, as well as headache specialists. There were about 400 presentations given during this time! One scientific session of note was on cortical spreading depression and migraine aura. Presenters described molecular, biochemical, and electrical activity during the aura and linked to how an aura could produce pain. One plenary session was tackling idiopathic intracranial hypertension (IIH). North American Neuro-ophthalmology Society (NANOS) members Alexandra Sinclair reviewed mechanisms likely involved in IIH and also biomarkers that we could use in studying the disease. She reported on studies that implicate cardiovascular disease associated with IIH. She also discussed how calcitonin gene–related peptide (CGRP) contributed to the headache in IIH, and when antibodies to CGRP are used to prevent the headache, papilledema may resurface without warning of headache. Another NANOS member, Susan Mollan reported on the Digre: J Neuro-Ophthalmol 2021; 41: e785 outcome of a recently completed randomized trial of standard weight loss therapy to bariatric surgery and proved that not only was bariatric surgery better for weight loss than a weight loss program but also cerebrospinal fluid pressure reduced significantly with bariatric surgery and weight loss. Furthermore, 24% weight loss is needed to normalize the intracranial pressure. Rigmor Jensen discussed the many questions and knowledge gaps in IIH guidelines for treatment. There were other abstracts that showed how optical coherance tomography was helpful in IIH and an animal model of IIH was demonstrated. Deborah Friedman presented on the most bothersome symptoms that bother patients with migraine including nausea and photophobia. There were many topics that would have interested neuro-ophthalmologists, including dry eyes and its overlap with migraine, as well as mechanisms of photophobia. There were 1,985 participants from 96 countries. Kathleen B.
