A 64-year-old male, working at a mountain site in Taitung County, suffered from primary open angle glaucoma (POAG) post trabeculectomy with well-controlled intraocular pressure (IOP) in both eyes (OU). He presented with headache accompanied by red eyes (OU) for 10 days. Physical examination revealed fever up to 38.2°C, neck stiffness, one eschar at the left forearm and another at the left ankle. Abnormal laboratory data indicated bacterial infection with central nervous system involvement. Ophthalmic examination showed elevated IOP, moderate conjunctival congestion, subconjunctival hemorrhage, anterior uveitis, cotton-wool spots on the retina and multiple white dots on the temporal retina (OU). Under the impression of uveitis in tsutsugamushi disease with atypical meningitis, oral doxycycline, anti-glaucoma and anti-inflammation eye drugs were prescribed. IOP returned to 12 mmHg and anterior uveitis subsided. The lesions of cotton-wool spots on the retina disappeared within 2 weeks, but multiple white dots remained persistently on the temporal retina.
