Severe Adult Still’s Disease Complicated by Purtscher-Like Retinopathy Treated with Intravenous Pulse Methylprednisolone and Tocilizumab

Abstract

Adult Still’s disease (ASD) is a rare systemic inflammatory disorder in which ocular manifestations have rarely been described. We report a 29-year-old Japanese woman with a rare case of refractory ASD complicated by Purtscher-like retinopathy. She was diagnosed with ASD and started on a high dose of oral prednisolone. Two days after the initiation of the treatment, she presented with blurred vision in the left eye, and the funduscopic examination revealed bilateral Purtscher-like retinopathy. Despite treatment with high-dose oral prednisolone for 2 weeks, she developed macrophage activation syndrome. Considering the severity of ASD, intravenous pulse methylprednisolone therapy and tocilizumab injection were administered. Although all the laboratory data and Purtscher-like retinopathy gradually improved, nerve fiber layer defect (NFLD) in both eyes appeared and visual field defect remained corresponding to the NFLD. In conclusion, Purtscher-like retinopathy might be useful as a poor prognostic factor of ASD, which needs appropriate systemic immunosuppressive treatment. Early detection and long-term follow-up of Purtscher-like retinopathy is important because it has the possibility of developing permanent visual field defect.
