Bilateral Occlusive Retinal Vasculitis in a Patient with Dermatomyositis.

ABSTRACT

A 48-year-old woman with a history of dermatomyositis (DMS) presented with 2 weeks of worsening myalgias, weakness, and diffuse edema following cessation of her systemic immunosuppression and subsequently developed severe bilateral vision loss consistent with bilateral frosted branch angiitis. Multimodal imaging was performed, and the patient was successfully treated with pulse-dose steroids and intravenous immunoglobulin, as well as intravitreal aflibercept. Ophthalmic involvement of DMS is typically limited to episcleritis, conjunctivitis, and uveitis. We present an uncommon case of bilateral occlusive retinal vasculitis with frosted branch angiitis in a patient with DMS. The significant improvement anatomically and in visual acuity in our patient suggests a role of combined anti-vascular endothelial growth factor and systemic immunosuppression in the management of DMS -related frosted branch angiitis. We suggest that retinal vasculitis should be considered in patients with known DMS and acute vision loss, with prompt referral for ophthalmologic evaluation.
