To report a case of uveitis in both eyes caused by Sweet's syndrome.

A 66-year-old male presented with decreased visual acuity in his left eye. Three years prior he was diagnosed with Sweet's syndrome, with symptoms such as chill, fever and, maculopapular rash on the chest. At initial physical examination, he had 3 or 4+ inflammatory cells and flare in the anterior chambers of both eyes, as well as hypopyon in his left eye. Under the suspicion of uveitis caused by Sweet's syndrome, he was rescribed an IV steroid injection and topical steroid agent. Three days later, his visual acuity improved to 0.3 in the right eye and 0.2 in the left eye. Hypopyon in the left eye disappeared and inflammatory cells decreased to 1~2+. He showed signs of recurrence in both eyes after 5 months and was treated with posterior subtenon triamcinolone injection in each eye. The patient showed no signs of recurrence for 10 months after injection.

We report a case of uveitis caused by Sweet's syndrome treated with a steroid agent resulting in good prognosis. To the best of our knowledge, this is first case of uveitis caused by Sweet's syndrome reported in Korea.
