Elusive diagnosis of Behcet\u27s disease in setting of painless vision loss.

Behcet\u27s disease is a chronic, idiopathic vasculitis with multisystem involvement commonly characterized by the classic triad of oral lesions, genital ulcerations, and uveitis. We discuss the case of a 22-year-old woman with a long-standing history of oral ulcers and vulvovaginal burning who presented with acute painless uveitis. With this presentation, there was an initial concern for infectious retinitis for which she was started on systemic antiviral therapy. Subsequent infectious disease workup was ultimately negative. Given her medical history and current presentation, she was diagnosed and treated for an acute inflammatory episode of ocular Behcet\u27s disease. The patient\u27s vision returned to baseline prior to discharge after treatment with systemic glucocorticoids. The diagnosis of Behcet\u27s disease in the setting of painless vision loss can oftentimes be elusive. However, it is important for clinicians to keep this condition as a differential diagnosis in patients presenting with acute onset uveitis as the progression of Behcet\u27s disease can lead to severe vision loss and blindness without prompt and adequate treatment
