Introduction: Capnocytophaga species are rare keratitis-causing pathogens. We herein report a case of keratitis caused by a drug-resistant Capnocytophaga species in association with contact lenses.Case presentation: A 64-year-old female who wore a contact lens in her right eye to facilitate repair of the corneal epithelium complained of infection and discharge. Slit-lamp biomicroscopy showed corneal abscessation and hypopyon. Thus, infectious keratitis was diagnosed. Direct microscopy and bacterial culture of a corneal scraping were performed. Because direct microscopy demonstrated the presence of Gram-negative rods, we began treatment with topical 1.5 % levofloxacin and 0.3 % tobramycin every hour. The corneal infiltration increased 4 days after initiating the therapy. The culture report confirmed the presence of a Capnocytophaga species with fluoroquinolone and aminoglycoside resistance and susceptibility to cephalosporins and minocycline. We switched to topical 0.5 % cefmenoxime every hour and oral minocycline at 200 mg day 21. The corneal inflammation subsided within 2 weeks. The bacterial isolate was identified as Capnocytophaga sputigena using 16S rRNA sequencing. Conclusions:We encountered a case of keratitis caused by C. sputigena with reduced fluoroquinolone and aminoglycoside susceptibility.

【Purpose】We reported a case of pediatric cataract that required cataract surgery despite of no abnormalities detected by the Spot TM Vision Screener (SVS). 【Case】A 4-year-old boy was detected with poor vision in the right eye in a medical checkup for 3-year-old children. Although autorefractometry showed variation in the astigmatic power and a decline in the confidence coefficient, the SVS indicated normal finding. The right and left visual acuities were 0.2 and 1.0, respectively, without correctors. The right eye was diagnosed with posterior subcapsular cataract and posterior lenticonus. No abnormalities were found in the 別冊請求先(〒 431-3125) 静岡県浜松市東区半田山 1-20-1
