Plain-English summary
This case report discusses a rare eye infection caused by a bacteria called Capnocytophaga canimorsus, which is often found in the mouths of dogs and cats. The patient, who had surgery on their eye ten years earlier, developed symptoms like redness in the eye and a problem with the surgical site after being licked by a dog. They were treated with antibiotic eye drops and had another surgery to fix the issue, which resulted in a good improvement in their vision. The infection was confirmed through lab tests that grew the bacteria. Overall, the treatment was successful.
Abstract
BACKGROUND: Capnocytophaga canimorsus is a facultative anaerobic, slow-growing, capnophilic, Gram-negative bacillus, that is commonly found in the microflora of canine and feline oral cavities. Capnocytophaga infections are an emerging zoonotic disease that can cause fatal systemic infections in immunocompromised individuals. Localized ocular Capnocytophaga infections, including keratitis, blepharitis, and endophthalmitis, can lead to severe eye threatening situations. To our knowledge, there is currently no documented case of Capnocytophaga canimorsus blebitis with bleb perforation after trabeculectomy. CASE PRESENTATION: Our case report and literature review features a novel case of Capnocytophaga blebitis that occurred after trabeculectomy, associated with close dog contact (i.e. face licking). The patient had underwent trabeculectomy 10 years prior and presented with conjunctival injection, perforated bleb, and hypotony. Overall, patient was medically treated subconjunctival vancomycin, gentamicin and moxifloxacin drops. Trabeculectomy revision was performed with good visual outcome. Bacterial cultures grew Capnocytophaga canimorsus. CONCLUSIONS: We discuss the strategies for diagnosis, treatment, and common risk factors for ocular Capnocytophaga infections. At-risk patients with ocular infections should be asked about close contact with dogs and cats; and treated promptly with the proper antibiotic regimen.
