Bilateral Retinal Vasculitis as the First Presentation of Systemic Lupus Erythematosus

BACKGROUND Systemic lupus erythematosus (SLE) can involve any part of the eye. Keratoconjunctivitis sicca (dry eye) is the most common ocular manifestation, followed by scleritis, episcleritis, and retinitis. Retinal disease affects around 10% of patients with SLE. Mild retinopathy may be asymptomatic. However, severe cases can cause visual loss requiring urgent ophthalmic evaluation. CASE REPORT We present a case of bilateral retinal vasculitis as the presenting manifestation of SLE. A 14-year-old girl with a history of schizophrenia presented to the emergency department (ED) with generalized weakness. Four days before her presentation, she developed itching in her eyes and frontal headaches. In the ED, she reported blurry vision in her left eye only and diffuse arthralgia. The ophthalmic evaluation showed bilateral reduced visual acuity, worse in the left eye. Both eyes had diffuse hemorrhages, white retinal lesions, and blurred optic disc margins. She was diagnosed with panuveitis and retinal vasculitis. The patient was then found to have SLE, diagnosed by the presence of arthralgias, panuveitis, severe bilateral retinal vasculitis, positive ANA and anti-dsDNA, and normocytic anemia. The patient received intravenous methylprednisolone with subsequent oral prednisone upon discharge, hydroxychloroquine, and azathioprine. One year after her presentation, she had significant visual improvement and no other system involvement. CONCLUSIONS Retinal vasculitis, as the presenting symptom of SLE, has been overlooked in large studies. However, the number of case reports documenting this as a presenting symptom, often with minimal or no organ involvement, suggests that upon diagnosis, patients might benefit from a skilled ophthalmic evaluation.
