Asymmetric optic disc edema in a young patient with POEMS: A rare presentation of a rare disease

PURPOSE: To describe a case of asymmetric optic disc edema presenting as the initial ocular feature of POEMS (Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy, Skin changes) syndrome. OBSERVATIONS: A 29-year-old female patient presented with 3 weeks history of blurred vision, proptosis, and peripheral neuropathy as well as hypothyroidism. Fundoscopy revealed optic disc edema associated with visual loss in the left eye. Following a computed tomography (CT) scan and a positron emission tomography/CT (PET/CT) scan which respectively revealed hepatomegaly and multiple osteosclerotic lesions, as well as laboratory findings of monoclonal gammopathy and elevated vascular endothelial growth factor (VEGF) levels, she was diagnosed with POEMS syndrome. After treatment with an autologous stem cell transplant, the optic disc edema and blurred vision resolved. CONCLUSIONS AND IMPORTANCE: The most reported ocular manifestation of POEMS syndrome, a rare and complex multisystem disorder, is bilateral optic disc edema that typically occurs in older males. Therefore, this report presents an uncommon case of asymmetric optic disc edema in a younger, female patient.
