Show Neuro-Ophthalmology News The 59th Annual International Society for Clinical Electrophysiology of Vision Meeting in Liverpool, United Kingdom Section Editors: Kathleen B. Digre, MD Meagan D. Seay, DO T he 59th annual meeting for the International Society for Clinical Electrophysiology of Vision (ISCEV), hosted by Professor Tony Fisher and colleagues, occurred from August 3rd through 6th, 2022, at the University of Liverpool in Liverpool, United Kingdom. This was the first ISCEV in-person meeting since the COVID-19 pandemic and welcomed 146 attendees. Feeling a bit of an outsider, as a first-time attendee whose main practice is neuroophthalmology, I was quickly welcomed into this small, but quite cordial group. The main ISCEV meeting was preceded by a 2-day ISCEV course and also featured a joint meeting with the British Society for Clinical Electrophysiology of Vision (BriSCEV). The clinical course educated learners on the electrophysiologic origins of electroretinography (ERG), electro-oculography (EOG), and visualevoked potentials (VEP) and clinical applications of these tests. Attendees came from a variety of worldwide locations and backgrounds, including researchers, clinical scientists, clinicians, technicians, and even veterinary medicine. The main ISCEV meeting featured 9 platform sessions and 2 poster sessions. There were a variety of topics, including “What is normal, “Genotype–Phenotype Correlation,” “Preclinical Retina,” and “Clinical Applications.” I discovered that electrophysiologists not only love their field but also love socializing and exploring the local culture (Fig. 1). This was evident by the multiple social activities provided throughout the stay. Gatherings included dinner at the Florist (Fig. 2), a restaurant in a building of the former School for the Blind. No trip to Liverpool would be complete without a taste of the Beatles, which was experienced on the Mersey Ferry (Fig. 3), featuring a Beatles cover band. The traditional ISCEV Olympics also took place at Abercromby Square pitting 3 teams from the representative continents (Fig. 4). Games this year included “horse-racing” relays and FIG. 2.

One may be wondering why the ISCEV meeting is being highlighted in the Journal of Neuro-Ophthalmology (JNO). However, neuro-ophthalmologists are becoming more frequently involved in their institution's visual electrophysiology, making ISCEV a useful, educational group for many of us. The FIG. 1.

She stressed the importance of having mitigating strategies in your office if you do these injections including oxygen, ambu bag, and taking a patient's weight and calculate the dose of the injected anesthetic. Although bupivacaine has been implicated the most, lidocaine can also cause it. Another lecture highlighted that during the pandemic, our patients are more irritable, and across the country, there is an increase in verbal and even physical aggression. This has led to shortages in nurses, technicians, and providers from burn out. Importantly, we as providers must protect ourselves and our staff and not tolerate abuse and keep ourselves safe. In particular, reporting these to officials is important. Also, some states allow patients to record their visit without the consent of the provider, and few states have mutual recording permissions—meaning that the patient needs the provider's permission to record the visit. Finally, of course, there was an entire session devoted to both high and low intracranial pressure, and 3 neuroophthalmologists participated in this session. Dr. Marie di Nome presented on vision and papilledema and how to follow and treat. Dr. Kathleen Digre presented on issues in idiopathic intracranial hypertension (IIH). Dr. Deborah Friedman covered the MRI diagnosis of IIH—stressing you cannot make the diagnosis from MRI alone. This year, as with last year, one could attend in person or virtually. In fact, you can still register and listen to lectures and receive up to 47 American Medical Association Category 1 Credits! https://americanheadachesociety.org/events/2022-scottsdale-headache-symposium/ E very year, the Scottsdale Headache Symposium is a real jewel for headache education. Held at the JW Marriott Camelback Inn in a relaxed atmosphere, one can learn headache medicine in a weekend. This year as with many other years, there was plenty for a neuro-ophthalmologist to learn. The organizing committee was led by our own Dr. Deborah Friedman; so you know there was neuroophthalmology sprinkled around the headache symposium! Some highlights of the sessions included learning the cerebellum is playing a role in photophobia. The cerebellum is chock full of calcitonin gene-related peptide (CGRP) receptors and may play a role by modulating the posterior thalamus and contributing to light aversion and photophobia. A migraine preventative, atogepant (a small molecule gepant that blocks CGRP) approved for episodic migraine has weight loss associated with it with very few side effects. Many of our patients with migraine may benefit from this new therapy. Indomethacin responsive headaches that we see in neuro-ophthalmology, such as hemicrania continua and paroxysmal hemicranias, can respond to neuromodulation by the external vagal nerve stimulator. This has very few side effects and may be helpful to our patients. An update on coronavirus was also really informative. Secondary headaches seen with COVID include headaches related to venous sinus thrombosis, posterior reversible cerebrovascular syndrome, and cervical artery dissection. New daily persistent headache may also follow. Long COVID is associated with headache at least 21% of the time. There were updates on cannabinoids and psychedelics for treatment of migraine and cluster headache. Psilocybin has been found particularly helpful for cluster headache. One particularly important plenary was on office and practice safety. Dr. Deborah Friedman presented a case of LAST syndrome—“local anesthetic systemic toxicity”— from the use of bupivacaine and other related drugs (1). The syndrome consists of dizziness, seizure, bradycardia, e62 Dr. M.
