Purtscher-like retinopathy associated with systemic lupus erythematosus treated with rituximab plus low-dose interleukin-2: A case report.

Purtscher-like retinopathy, an occlusive microvasculopathy, is a rare and severe ophthalmic complication of systemic lupus erythematosus (SLE) characterized by a sudden loss of vision with retinal whitening, cotton wool spots and minimal intraretinal hemorrhage. Recovery in visual acuity is usually poor even with prompt treatment. This case showed a patient with SLE concurrent Purtscher-like retinopathy treated with rituximab and interleukin-2 (IL-2) with good prognosis. A 16-year-old female with a 2-year history of SLE was admitted because of unrelieved disease activity of SLE when treated with a high dose of corticosteroids and immunosuppressants and she further suffered from reduced visual acuity in both eyes. She was diagnosed with Purtscher-like retinopathy secondary to SLE after ocular examination. Rituximab and low-dose IL-2 for systemic treatment and intravitreal injection of anti-vascular endothelial growth factor antibody to right eye were given. The SLE disease was completely relieved with the sight recovering and no recurrence of Purtscher-like retinopathy was reported during 6-year follow-up. Purtscher-like retinopathy associated with SLE should be treated early and promptly. Rituximab should be considered in SLE patients with Purtscher-like retinopathy who have an incomplete response to initial immunosuppressive therapy and low-dose IL-2 may help induction of clinical remission.
