Ophthalmoplegia Associated With Extramedullary Multiple Myeloma: Case Series From a Tertiary Cancer Center.

Background: Multiple myeloma (MM) is a malignant disorder of plasma cells that results in tumor cells replacing the bone marrow. In extramedullary MM (EMM), however, tumor cells proliferate outside the bone marrow. EMM may produce ophthalmoplegia through direct invasion of the superior orbital fissure, cavernous sinus, and/or sphenoidal sinus.

Highlights on Ocular Toxicity of Immune Checkpoint Inhibitors at a US Tertiary Cancer Center.

Introduction: Immune checkpoint inhibitors (ICIs) have improved prognosis in advanced malignancies; however, they may be associated with extensive ocular immune-related adverse events (irAEs) that are sight threatening. Our study aimed to identify the presentation, characteristics, management, and clinical outcomes of ocular irAEs.

Methods: In this retrospective, observational case series, we reviewed the medical records of 1280 patients at a large US tertiary cancer center between 2010 and 2020.
