The authors report a Tsutsugamushi patient who has intermediate uveitis and rhegmatogenous retinal detachment without a typical skin eschar, which may be rare.

The authors present a case of a 63-year-old man who complained of fever, chills, and headache, with lymphadenopathy, hepatomegaly, reticulonodular pneumonia, and blurred vision in the right eye after descending a mountain in autumn. Serological findings showed elevated titers for strains of Rickettsia tsutsugamushi , even though no eschar could be found on his body. In addition, the ophthalmologic examination disclosed vitreous opacity as uveitis in his right eye; thus, the patient was treated for Tsutsugamushi disease. However, retinal detachment was found in his right eye even after treatment. Thus, a vitrectomy and intravitreal silicone oil injection was performed, and the patient's best corrected visual acuity improved from hand motion to 0.04 on the 7th day after the operation.
