NOVEL/Editorial Board/Curriculum Committee Meeting


OMIC Symposium

The lecture will present a review of recent lawsuits alleging failure to diagnose giant cell arteritis (GCA) and the challenges of defending those claims. We will offer risk management recommendations for preventing GCA claims, including how a thorough medical history, quality of communication between staff and physicians, and coordination of care with other providers can lead to earlier diagnosis. OMIC’s sample GCA checklist will also be discussed.


Hot Topics

Moderators:  Marc Dinkin, MD, and Meagan D. Seay, DO

This session will review a variety of up-to-date, clinically relevant, neuro-ophthalmic topics.

Presenters will discuss the utility of tPA in acute treatment of central retinal artery occlusions (CRAO) and present data from a large single-health-system regarding experience with acute treatment of CRAO. The session will then transition to physician use of social media where attendees will learn about the evolution of social media, potential adverse effects, followed by the future of social media in practice development and education. This will be followed by a presentation on ocular imaging, with focus on optical coherence tomography angiography (OCT-A) and OCT enhanced depth imaging (EDI), along with a flash overview of additional future clinically useful imaging modalities. The session will wrap up with two presentations on visual snow syndrome, including appropriate workup and differential diagnoses to ensure we are not missing a secondary etiology of visual snow syndrome, along with updates on pathophysiology and treatments.

Upon completion of this sessions, participants should be able to: (1) review the latest data and real-world experience from a single-health-system regarding acute treatment of central retinal artery occlusions, (2) describe the impact that physician use of social media has, for better and worse, on patient care and education, (3) review modern ocular imaging modalities and identify use of these modalities for better patient care, and (4) review appropriate diagnostic techniques, pathophysiology, and treatment of visual snow syndrome.

State of the Art - Global Perspectives

Moderators: Claire Fraser, MBBS and Karl Golnik, MD

In this session we will hear the international perspective on the diagnosis and management of two common neuro-ophthalmic presentations. First, we will discuss a case of optic neuritis. Each speaker will approach this case from the perspective of the underlying diagnosis and associated management that is most common in their local hospitals. Our European speaker will discuss ON related to multiple sclerosis. From America and Asia ON related to myelin oligodendrocyte glycoprotein and neuro-myelitis optica will be discussed. We will hear about infective optic neuritis and the presentations seen in an Indian setting. This will highlight all major causes of optic neuritis from an international perspective and provide an insight into management of patients that might come to our clinics from different geographical areas and ethnic backgrounds. Second, we will discuss a case of idiopathic intracranial hypertension (IIH).  Our two speakers will discuss similarities and differences in management style between their institutions.  This will allow us to critically evaluate our own practices and how the experience of other centers might help in our own management.

Upon completion of this session, participants should be able to: (1) appraise different types of optic neuritis presentations, (2) employ different management strategies in patients with IIH and (3) formulate different management options depending on the type of optic neuritis.

Ophthalmic Surgery in the Neuro-Ophthalmic Patient

Moderators: Chantal Boisver, OD, MD and Ellen B. Mitchell, MD

Because neuro-ophthalmology encompasses so many diseases, there are diverse options for a surgical practice. Even for non-surgical neuro-ophthalmologists, it is extremely important to understand the different procedures that can be performed and be aware of potential pitfalls for the patients seeking surgical alternatives. A panel of surgical neuro-ophthalmologists that perform these procedures would address different scenarios emphasizing potential pitfalls and counseling of patient.

Upon completion of this session, participants should be able to: (1) describe the pros and cons of premium intraocular lenses in patients with a history of optic neuritis, (2) identify the limitations of LASIK surgery in patients with double vision, (3) outline the challenges of lid surgery for the treatment of blepharospasm, (4) discuss the implications of a prior NAION when counseling patients undergoing cataract surgery, (5) list the indications/limitations of performing a second ONSF, and (6) summarize the medical and surgical treatment options in Thyroid Eye Disease.

Many of Daniel Jacobson's papers were based upon careful observations and important questions arising in neuro-ophthalmic patients he saw in his practice.  This year’s speaker, Grant Liu, has emulated this approach in his academic career.  This talk will highlight Dr. Liu’s contributions to the understanding of the demographics, designing the diagnostic criteria, and improving the management of pediatric pseudotumor cerebri syndrome.

Upon completion of this session, participants should be able to: (1) describe the demographic differences between adults and children with pseudotumor cerebri syndrome, (2) apply the reference range for CSF opening pressure in children, and (3) employ the diagnostic criteria for pediatric pseudotumor syndrome.
