The Application of Optical Coherence Tomography Angiography in a Patient with Systemic Lupus Erythematosus.

A 15-year-old girl presented to the emergency department with a history of bilateral blurred vision for one day, with greater severity in the right eye. Fundus examinations revealed cotton wool spots, dot hemorrhage, and hard exudate. She underwent optical coherence tomography angiography (OCTA), which showed the presence of macula ischemia, decreased vascular density, mild retinal fluid, severe ischemia, some macular edema, and vascular sheathing, indicating active vasculitis in the right eye. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect many organs in the body, including the eye. Ocular involvement is one of the most well-known features. Retinal vasculitis is a rare complication of SLE that is characterized by vascular sheathing that can progress to vaso-occlusion. We report the clinical features of SLE using OCTA.
