Background. In advanced cutaneous melanoma, new systemic therapies include immunotherapy by checkpoint inhibition and targeted inhibition of the mitogen-activated protein kinase pathway; these are becoming increasingly well established. We describe the clinical presentation of uveitis in three patients with concomitant systemic melanoma treatment. History and Signs. Three patients with metastatic melanoma receiving systemic therapy (ipilimumab, vemurafenib) presented at our institution with a short history of ocular symptoms. Clinical findings included anterior uveitis, intermediate uveitis, disc swelling, inflammatory choroidal lesions and retinal vasculitis. Therapy and Outcome. All three patients responded well to local and/or systemic steroid treatment. In one case, the systemic anti-cancer drug was discontinued after the onset of uveitis. Conclusions. Ocular inflammation may occur in the setting of systemic melanoma therapy. Presentations of uveitis include Vogt-Koyanagi-Harada-like syndromes. Ocular inflammation can usually be controlled by topical and sometimes systemic corticosteroid therapy. However, treatment guidelines are not established and management of these patients demands close cooperation with the oncologist.
Inflammation of the episclera and sclera still represents a diagnostic challenge. Many of these presentations are idiopathic and are managed empirically with the use of anti-inflammatory therapy, usually with a satisfactory response. However, some cases will have a more aggressive nature or will show resistance to conventional therapy, and those potentially are connected to an infectious or underlying disease. In such cases, there is an increased risk of visual loss and severe systemic complications requiring intensive investigations and aggressive therapy. The diseases more commonly associated with these conditions, especially with scleritis, are the connective tissue disorders and systemic vasculitis, but systemic infections and malignancies also must be excluded. Management depends on the specific diagnosis, and every year a new list of potential associations or atypical presentations is reported. For a successful outcome, it is important that these presentations are recognized.
The quantiferon test is recommended in the evaluation of people with retinal vasculitis. Interpretation of a positive result can be challenging in a country nonendemic for TB. The majority of patients with quantiferon-positive retinal vasculitis were found to have latent TB.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
