An interview with Dr. Marc Ernstoff from the National Cancer Institute, author on “Management of Immune-Related Adverse Events in Patients Treated With Immune Checkpoint Inhibitor Therapy: ASCO Guideline Update.” He reviews identification, evaluation & management of ocular toxicities in patients receiving ICPis, including uveitis, iritis, and episcleritis in Part 12 of this 13-part series.

BRITTANY HARVEY: Hello, and welcome to the ASCO Guidelines podcast series, brought to you by the ASCO Podcast Network, a collection of nine programs covering a range of educational and scientific content, and offering enriching insight into the world of cancer care. You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today we're continuing our series on the management of immune-related adverse events. I am joined by Dr. Marc Ernstoff from the National Cancer Institute in Bethesda, Maryland, author on Management of Immune-Related Adverse Events in Patients Treated with Immune Checkpoint Inhibitor Therapy: ASCO Guideline Update, and Management of Immune-Related Adverse Events in Patients Treated with Chimeric Antigen Receptor T-Cell Therapy: ASCO Guideline. And today we're focusing on ocular toxicities in patients treated with immune checkpoint inhibitor therapy. Thank you for being here, Dr. Ernstoff. MARC ERNSTOFF: Thank you, Brittany. BRITTANY HARVEY: First, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The full conflict of interest information for this guideline panel is available online with the publication of the guidelines in the Journal of Clinical Oncology. Dr. Ernstoff, do you have any relevant disclosures that are directly related to this guideline? MARC ERNSTOFF: I have no further disclosures at this time. BRITTANY HARVEY: Great. Thank you. Then let's get into these ocular toxicities. So first, what are the immune-related ocular toxicities addressed in this guideline? MARC ERNSTOFF: So the ocular toxicity is addressed in the guidelines represent a relatively uncommon side effect of immune checkpoint inhibition, and represents inflammation of all components of the eye from the superficial component to the internal uveal component. So there is iritis. There's episcleritis and uveitis, are the ones that are usually identified by physical examination and by complaints. BRITTANY HARVEY: Understood. Then so let's start with what are the key recommendations for identification, evaluation, and management of uveitis and iritis? MARC ERNSTOFF: So those are excellent questions. I think that it's important for clinicians to recognize that while most of the eye toxicities are relatively minor, low grade, and can be managed effectively, there are some that are very important to identify, particularly as they may lead to blindness, particularly uveitis or pan uveitis. So identification of these symptoms and signs are important. So evaluation of the patient by asking whether there are any eye symptoms-- dryness or irritation-- is important in your evaluation of the patient's side effects. In addition, looking at the eye, both with a penlight, looking for any inflammatory signs, and doing a ophthalmologic examination to make sure there's no cloudiness or anything identified in the retina is important. BRITTANY HARVEY: Great. And then furthermore, what are the key recommendations for identification, evalu
